How to include STO PR availability check while DRP run?

Hello gurus,
I will explain my scenario by following ex.
1. Suppose i have a requirement in Plant A of quantity 500.
2. Plant B has stock of 800 Q
3. But there is a outbound STO PR of quantity 500 from PLANT B to Plant C.
4. So, now when i run DRP, it is creating STO PR of quantity 500 from plant B to Plant A (actually it should not happen as there is already outbound STO PR.... point 3)
My question is how i can take into consideration STO PR... Means actual available quantity in plant B should be 800-500 = 300.
Its not happening currently.
How can i activate this? Is there any customisation related to this in Availability check or in plant parameters.
Plz. help
Navin

Hello,
As explained in my earlier example.....
If there is a STO PR where
ex.
Supplying Plant is B - so for plant B it is outbound as stock is going out
Receiving Plant C - for plant C it is inbound as stock is coming in.....
so now look into my earlier example...u will understand it clearly....
and i m running DRP....BY Zprogram......to create STO pr and program is not considering the quantity of sto pr..
Please suggest...
thanks,
navin

Need to disable availability check while changing 'Reason For Order' Field in Retail Tab

While change of STO (Me22n) I want the availability check to be disabled when a change to 'Reason for Oder' is made in the Retail Tab in the item detail.
Let me know if there is any BADI/ User exit or enhancement available where i can do this customization.

Hi Reddy,
Try Transaction Variant, you can customize the screen using this tool.
Basically, you customize the screen (hide, make it required, visible etc) then
save it as screen variant and define a new transaction code to it.
So for your user, just give them this new transaction code (instead of SAP standard).
Detail about transaction variant can be checked on :

Longer time for Material Availability check while creation of prd order.

Hi guys,
I am facing a weird problem while creating production orders thru CO01.
I enter the component and plant and I am also using the forward scheduling option.
for some reason, SAP is taking a long time for material availability check when I hit the release button.
Sometimes its taking more than an hour. Its happening with few specific BOM's, and I have checked the master data but I could hardly find a problem in master data.
Can someone suggest me some tips ??
Thanks & Regards,
Sashivardhan

Hi,
Please check the Availability check control maintained for Components it should be 01 or 02. Also check the issue storage location maintained or not. You can maintain issue storage location in BOM in Status/lng text tab in Production Storage Location.
Hope this will help.

Navin

Delivery from projects not included in dynamic availability check

Problem:
In our client, we use deliveries for project (delivery type LP, delivery item type DLP) triggered from network reservations.
During delivery creation, we are finding that the existing deliveries are not being considered/cumulated into the ATP calculation. For example, for a given a material with an on hand balance of 22 units, individual deliveries for 4 units are created every day. The individual delivery passes the availability check test as it is always backed by the 22 units of stock. However, as a whole now the individual deliveries are totaling 80 units, exceeding the quantity on hand.
Is there any way to fine tune the availability check through customizing such that these deliveries for project created are included in CO09 and the delivery for project creation?
Or this should be an enhancement?. Client is in SAP R/3 version 4.7
Thanks,
Marco

STO Creation - Availability check

When you create an STO & if there is not enough stock in supplying plant, you got a WARNING message saying something like u201C of Material XXXXXX, only 49 EA are available on desired dateu201D. The STO is saved but the system put a date of 12/31/9999 into the COMMITTED DELIVERY DATE for that material/line item. Even when additional materials are available, since the COMMITTED DELIVERY DATE is 12/31/9999, SAP will not try to deliver them. Now the business is asking to change this warning message to error message (06 450 Message number). If I change this warning message to error message, I believe it will impact all other type of STO's, PO's & SO's also. We want this warning message to be changed to Error message only for a particular STO type. What are the options available to us.
Edited by: Csaba Szommer on Feb 2, 2012 8:33 AM

You can control document type by putting some logic in some user exit.Suppose If PO first line item has no stock available and other line items confirmed in this case if you make it error that message then you can not save the STO?.For smooth flow STO keep the message to warning and tell the Business to follow the process.If Business really insisted to stop creating the PO if any line item is not confirmed then you can try for user exit.

How much RAM should be in use while not running anything?

Just for the heck of it, I checked the Activity Monitor with nothing else open to see how much RAM was being used. Much to my surprise, nearly 900MB of my 2GB was being used with literally every application closed except for Activity Monitor. This can't be normal...

My Macbook Pro is also using about 1.3GB RAM with virtually everything shut down (mail, safari, ical, itunes, etc). Yet, my husbands uses only about 400-500MB with the nearly identical applications left running.
I have 4GB, he has 2GB.
We compared the running applications one-by-one, and mine uses nearly double his for the exact same application.
Does a laptop use more memory if it has more memory to use?
This really bothers me. There does not seem to be any reason for mine to be consuming more RAM when running the same small applications as his does yet I can't figure out why?
Ahhhhh!

What is availability check concept how it is used in SAP

hi friends,
i don't know what is availity check,how is it used and how it should be configured,please help me.

Availability Check in Sales and Distribution Processing
There are three types of availability check:
     Check on the basis of the ATP quantities
     Check against product allocation
     Check against planning
In Customizing, you determine whether an availability check is to be carried out against the ATP quanitity or against planning. The check against product allocations is controlled in the material master and elsewhere in the system.
Check on the Basis of the ATP Quantities
The ATP quantity (ATP = Available To Promise) is calculated from the warehouse stock, the planned inward movements of stock (production orders, purchase orders, planned orders) and the planned outward movements of stock (sales orders, deliveries, reservations). This type of check is performed dynamically for each transaction, taking into account the relevant stock and planned goods movements with or without replenishment lead time. Planned independent requirements are not taken into account here.
Check against Product Allocation
Product allocation facilitates period-based distribution of products for certain customers or regions. As of Release 3.0F, you can carry out an availability check against product allocation. This ensures, for example, that when production is low, the first customer does not get the full amount, resulting in following sales orders not being confirmed or being confirmed far too late.
Check against planning
The check against planning is performed against independent requirements which are usually created for an anonymous market rather than being customer-specific (for example, in the strategy Planning without assembly, when production occurs only up to the stocking level). The planned independent requirements result from demand program planning and are used for planning expected sales quantities independent of orders
Controlling the Availability Check in Sales and Distribution Processing
You control the availability check using general and SD-specific control features.
General Control Features
The following control elements need to be maintained in Customizing and in the material master record:
     Strategy group
The allowed planning strategies (main strategy and further possible strategies) are combined in the strategy group. As of Release 3.0, the strategy group is specified in the material master record in the MRP 1 Screen. In Customizing, strategy groups are assigned, dependent on plant, to MRP groups. If the strategy group is missing in the material master record, it is determined on the basis of the MRP group, if it has been maintained.
Up to Release 3.0, the strategy group is determined on the basis of the MRP group
     MRP group
The MRP group combines materials from the point of view of material requirements planning. This enables you to control planning for these materials in a particular way using, for example, the strategy group, consumption mode and planning period. You enter the MRP group in the material master in the MRP 1 screen. The strategy group is determined from the MRP group.
     Planning Strategy
The planning strategy specifies the requirements type for planning and customer requirements. This represents the decisive control feature for the interaction between Production Planning and Sales and Distribution.
     MRP type and item category
If no requirements type is found using the planning strategy, the system tries to determine a corresponding requirements type on the basis of the MRP type and the item category.
Until 3.0C, determination of the requirements type via planning strategy has taken priority. This is not always the best option, however, as the following example will show. A requirements type is determined for a material, which causes availability to be checked against planning. In consignment stock processing, however, availability should be checked against stock. Until 3.0C the availability check had to be deactivated in these cases. As of Release 3.0C, you can determine how the requirements type is to be determined for each transaction by maintaining the Source field in Determination of requirement types using transaction in Customizing.
     Requirements type
The various requirements are identified by their requirements type. The requirements type refers to the requirements class and its control features.
     Requirements Class
The requirements class contains all control features for planning such as relevance for planning, requirements planning strategy and requirements consumption strategy. In addition, it is specified at a global level whether an availability check is to take place for the material in the sales and distribution documents on the basis of the ATP quantity (ATP = available to promise) and whether requirements are to be passed on. A finer degree of control can be obtained for sales documents using the schedule line category.
Control Features Specific to Sales and Distribution
The following SD-specific control features need to be maintained in Customizing:
     Checking group
The checking group controls whether the system is to create indivdual or collective requirements in sales and shipping processing. In addition, a material block for the availability check with transfer of requirements can be set here. The checking group can also be used to deactivate the availability check. This option was created especially for the assembly order so that when the bill of material is exploded in the assembly order, the individual components, if necessary, can be classified as non-critical parts as far as procurement is concerned.
The checking group specifies in combination with the checking rule the scope of the availability check. It is proposed in the material master record on the basis of the material type and the plant, and copied into the sales and distribution documents.
     Checking Rule
You use the checking rule to control the scope of the availability check for each transaction in sales and distribution. You also specify whether the check should be carried out including or excluding replenishment lead time. The individual checking rules define by transaction, which stock and inward and outward movement of goods should be taken into account for the availability check.
     Schedule line category
You can control with the schedule line category whether an availability check and transfer of requirements should be carried out in the sales documents. The possible settings for this at schedule line level are dependent on the settings in the requirements class which is determined from the requirements type of the material.
     Delivery item category
The delivery item category can be used to control whether an availability check takes place in deliveries.
Prerequisites
An availability check can only be carried out if the following prerequisites have been fulfilled:
     The control elements described above for the availability check must be maintained in Customizing for Sales and the relevant assignments made to the sales transactions
     The availability check must be switched on at requirements class level and - for the availability check in the sales documents - at schedule line category level
     A requirements type must exist by which the requirements class can be found
     A plant must be defined. It can either be proposed from the customer or material master record or can be entered manually in the document.
     A checking group must be defined in the material master record on the Sales/plant data screen in the Availability check field
Timing of the Availability Check in Sales and Distribution Processing
When you create an order, the system determines the required materail availability date on the basis of the customers requested delivery date. On this date, you must begin picking, packing, labeling, and loading the goods. Therefore, this is the date of significance for requirements planning on which the availability should be checked.
The following data is required for determining this date:
     Route from the shipping point to the ship-to party location
     Shipping point from which the goods are issued
     Loading group from the material master record
     Weight group determined from the order using the order quantity
Scheduling
This data, which you have already entered in the system, means that scheduling can occur automatically. Since scheduling is carried out backwards from the requested delivery date, it is also called backward scheduling. If backward scheduling determines that the preparation for the shipping activities should have been started already to meet the customer's requested delivery date, the system then starts forward scheduling automatically from the current date.
Scope of the Availability Check in Sales and Distribution Processing
The following elements can be included in the availability check:
     Stock
o     safety stock
o     stock in transfer
o     quality inspection
o     blocked stock
     Inward/Outward movement of goods
o     purchase orders
o     purchase requisitions
o     planned orders
o     production orders
o     reservations
o     dependent reservations
o     dependent requirements
o     sales requirements
o     delivery requirements
Requirements in sales and distribution (sales requirements and delivery requirements) result from all transactions which forward a requirement to Materials Management (MM) or to Production Planning (PP). For example, this could include sales orders or deliveries and quotations as well. Sales and distribution requirements reduce existing stock or inward movements of stock on the material availability date to ensure that other outward movement of stock elements cannot access the quantity reserved in this way.
Requirements relevant for Sales and distribution are created in Sales and Distribution, whereas other elements in this list are created in Materials Management or in Production Planning.
Defining the Elements to be Included in Check
A checking rule is assigned to each transaction. This rule in combination with the checking group controls the scope of the availability check. You can use the checking rules in Customizing for Sales to specify for the various transactions which of the elements listed above should be included in the availability check.
For trading goods it does not make sense to include planned or production orders, for example, in the availability check. However, for products manufactured by your company these orders should be included in the check.
For transactions such as make-to-order production, consignment or returnable packaging processing that create special stock, the availability check is performed against special stock.
If it is defined by the checking rules that both sales and delivery requirements are taken into account in the availability check in sales documents but only delivery requirements are taken into account in the availability check in deliveries, there is a danger that quantities reserved in the sales documents are considered to be available by the availability check in the deliveries. This can lead to sales documents becoming backlogged.
Reactions to the Availability Check in Sales Documents
If the goods ordered by the customer are not available on the requested date, the system branches automatically during sales document processing to a further screen where delivery proposals are offered for selection. The system determines these proposals on the basis of the availability situation. This screen also provides you with information on the scope of the check, the current ATP quantity, and the availability situation across all plants.
Availability Control
On the Availability Control screen, you can choose between the following delivery proposals:
     One-time delivery on the requested delivery date
In this section, the system checks whether the requested delivery date can be kept to. If stock of the material is available to make a delivery on the requested delivery date, the stock quantity is confirmed here. If there is no stock available, confirmed quantity zero is displayed.
To copy this data into the sales document, select Edit One-time delivery.
     Complete delivery
In this section, the system checks whether there will be sufficient stock for complete delivery at a later date:
o     If there is sufficient stock available at a later date to cover the required quantity in the sales document, the system proposes the date here.
o     If the system determines that complete delivery cannot be made at a later date, no date is proposed in this section.
When availability is checked including replenishment lead time, the date which is proposed in this section is the date on which the replenishment lead time period ends if the stock before the end of replenishment lead time does not cover the order quantity.
When availability is checked excluding replenishment lead time, the system bases its calculations on the stock and the planned inward movements of stock.
To copy this data into the sales document, select Edit Complete delivery
     Delivery proposal
In this section, the system checks whether and for which dates partial deliveries can be made. Partial deliveries are displayed for different dates. These dates are based on the planned inward and outward movements of stock.
During an availability check which takes replenishment lead time into account, the date on which replenishment lead time ends is displayed if insufficient stock means that no partial deliveries can be made before replenishment lead time ends.
During an availability check which does not take replenishment lead time into account, the system displays the dates on which partial deliveries can be made with the available stock.
To copy this proposal into the sales document, select Edit Delivery proposal
The dates displayed in the sections complete delivery and delivery proposal are determined from the material availability date using forward scheduling and represent actual delivery dates.
Availability Across Plants
You can display the availability situation in the various plants for which a material is maintained. To do this, proceed as follows:
1.     Select Goto Other plants on the availability control screen.
The dialog box Plant Selection appears. All plants for which the material is maintained are displayed.
2.     Mark the plants in which you want to check availability and select Check plants.
You reach the Availability Check: Overview screen. The requirements quantity and the quantity which could be confirmed as well as some additional information is displayed in a separate line for each plant you selected.
3.     If you require detailed information on the availability check for a particular line, select the relevant line and select Edit Check availability.
You reach the Date proposals dialog box where the detailed data is displayed.
4.     You can select a plant with sufficient quantity for confirmation to be copied automatically into the Overview screen. Select the appropriate line and select Edit Copy plant.
Using the user exit USEREXIT_PLANT_SELECTION in the Include LV03VFZZ you can make a preselection of the allowed plants. If you use this option, the Plant selection dialog box does not appear and the availability check is performed immediately for the allowed plants. If, on the basis of information resulting from the availability check, you want to deliver from a plant other than the one specified in the item, you must at present enter this plant manually in the item. In a later release, however, you will be able to select the plant directly from the list of plants.
Displaying the ATP Quantities
If you want to display the current ATP situation on the availability control screen, select Goto Availability overview.
Displaying the Scope of the Check
If you want to display the scope of the check (stock and inward/outward movements of goods taken into account during the availability check) from the availability control screen, select Goto Scope of check.
Delivery Agreements in the Customer Master Record
A customer may react in different ways to the fact that a complete delivery can not be provided for the required delivery date. You can define in the customer master record, the way a customer reacts to the inability to meet the requirements represented by the key data.
     The customer wants complete delivery of all items by the requested delivery date or at a later date.
The complete delivery indicator is copied into the sales document from the customer master record. To find it, select Header Business data on an overview screen or a header screen. You find the indicator in the Shipping section.
If the complete delivery indicator is set in the sales document, the individual items are automatically correlated when the document is saved if the schedule lines exist for various dates (that is, a delivery group is automatically created for the sales document items and the latest delivery date within this group becomes the group delivery date). For further information on delivery groups, see Combining Sales Document Items for Delivery.
     The customer only allows a certain number of partial deliveries for each item.
The partial delivery indicator and the number of partial deliveries are copied into the sales document item from the customer master record. To find the indicators:
1.     Go to the Business Data screen for this item.
2.     Select Edit Shipping details.
The indicators are found in the Shipping section.
Performing the Availability Check Again
Usually, an availability check is only performed when a sales document is created. If quantities or dates are changed in the document and availability needs to be checked again, the check is performed again automatically . However, you can also initiate an availability check manually.
Automatic Checks
In the following situations, a new availability check is automatically carried out:
     Quantity change
     Date change (requested delivery date, material availability date)
     Change to the fixed data
     After new delivery scheduling (for example, the route or shipping point has been changed)
     Change of plant
     Change of storage location or batch
     Removal of blocks which affect requirements
     Removal of reasons for rejection
Initiating a Check Manually
In the sales document, you can initiate a new availability check manually. If you want to perform an availability check for all items in a sales document, select Sales document Check availability on the header screen. If you want to check availability for an individual item, select Edit Item availability.
Fixing Quantities and Dates in Sales Documents
If the availability check for an item determines that the item cannot be delivered fully on the requested delivery date, and, as a result one or more schedule lines have to be created for later delivery dates, the customer can decide whether to accept these delivery dates and quantities.
You can record the customer's decision either by setting an indicator in the Fixed date and qty field or by leaving this field blank. The field is displayed both on the schedule line overview screen and on the availability screen.
Customer Accepts the Schedule Line Proposal
If the customer accepts the schedule lines which are proposed by the system, mark the Fixed date and qty field. The system then transfers the requirements for the schedule lines to material requirements planning.
Customer Requires Goods Earlier
If the customer requires the goods earlier than the date that the system can confirm after the availability check, leave the Fixed date and qty field blank. The system then only passes on the requirements for the requested delivery date and does not take the quantities and dates confirmed by the system after the availability check into account. In this case, it is assumed that the requested delivery date can be kept to because, for example, additional production capacity may become free. The system only confirms the sales order once the entire order quantity can be delivered on the requested delivery date. In the subsequent delivery processing, the sales order is only considered to be completed when the entire order quantity has been delivered or when all partial delivery agreements have been fulfilled.
A fixed item is considered to be completed once the entire confirmed quantity (which can be smaller than the originally requested order quantity)has been delivered. Therefore, it does not make sense to fix the confirmed quantity to 0 as the item is considered to be completed from the start.
During rescheduling, the fixed quantities and dates are no longer taken into account.
Blocking Confirmation of Quantities in Sales Documents
In Customizing, using Block transfer of requirements by delivery block, you can specify that certain delivery blocks in the sales document header also block the confirmation of order quantities.
If you enter such a delivery block in a sales order header, the system confirms the available quantity to show you the delivery options. If you save the document, however, the confirmed quantities are not saved. Your company could block confirmation for a customer if this customer's credit worthiness was questionable. The sales order in this case is not only classed as unconfirmed, it is also blocked for delivery.
Thus, no stock is reserved. The stock is still available for other customers. Although the order quantities are not confirmed, the system still transfers the requirements to material requirements planning. It is assumed that the delivery block will be removed at some point. The automatic transfer of requirements means that the order quantity can be confirmed at a later point in time

How to make material availability check work during Work Order creation

Hi Experts,
Kindly advice about these matters:
1. How to make material availability check work during Work Order creation?
My requirement is Work Order can not be created when it has missing parts. I have set the config to '3' can not created when is has missing parts, but it still does not work.
I have implemented SAP Notes 1148139 on my system (SAP ECC 6 Ehp 5) also, but still does not have any effect.
I must not set the config Res./Purch Doc creation to 'immediately', because it does not fit to my user requirement. Is there anyone knows how to solve this requirement?
2. How to make information message/ Availability check screen appear when sparepart is missing, without clicking Availability Check button? for example: appear when clicking Save button.
Thank you
-amoonra-

Hi Maheswaran,
I have implement the prerequisite notes. (Notes 790219 and 1034962). Do you know why it is still does not work?
Thanks

Ability to include Batch determination within Availability Check

Hi All,
My client has a requirement where the availability check must be driven based on the batches selected from the batch determination. This works fine when the line item is initially entered. However if the item gets backordered, there is no way to carry out batch determination again.
Has someone encountered this or a similar scenario. For clarity, here are the steps :
1. Sales order creation
- Enter line item
- Batch determination executed
- Availability Check carried out based on batch found
- Schedule line gets created with quantity determined.
2. Backorder processing
- Order is accessed
- Schedule line is accessed
- Availability Check carried out ( no batch determination executed ).
- Schedule line gets updated with the quantity determined.
If anyone has ideas or has worked on getting the batch determination triggered within the availability check or backorder processing, it would be great if you can share your experience here.

My requirement is as follows:
At the time of sales order creation system should check the availability check against the batch which is derived by the automatic batch determination.
Can you please tell me how to configure this senario (availability check on batch level)
Regards
J.Srivastava

Availability check

Dear All
We have a requirement that if a material say stock is 10 in unrestricted then we create a STO for 10 units then in MMBE say in a plant 1000 still unrestricted will be 10 but in that details there will be 10 units STCK TRPSTORDER REL (under this heading) 10 units is appearing
STO happening from plant 1000 to plant 1001
When an incoming sales order comes for that same material in the same plant then system allocates these 10 units to that order which we dont want to happen in the plant 1000
But when we initially make a sales order instead of STO if the unrestriced is 10 then it shows in sales order stocks (under this heading) 10 units is appearing in the plant 1000
When an incoming sales order comes then system does not allocate these 10 units to that order and says no stock which is our requirement
*In Simple stocks are getting reserved for open sales orders but not for open STOs with availability check in a plant*
This we want it for STO after creating PO itself
Note if the delivery is generated for STO then system says no stock for the incoming order which is fine
In OVZ9
1.include sales requirements is ticked
2. include rel ordd requirements (for STO is consideration is marked as X)
3.Include stock in transfer is ticked
Friends Expecting your valuable comments and suggestions
Stocks should be reserved for STO how do i control this in OVZ9?
Hope i am clear about my Requirement Any clarifications needed?
Regards
Raja

Dear Lakshmipathi
Thanks for the reply But that doesnt solve.Already checked there
But we have to control SD settings only in OVZ9 as the requirement is to check availability for sales order creation only
Scenario 1
In MMBE Plant is 1000 Material is A unrestricted stock is 10
We create a sales order no 1 for material A for 10 units in this plant and saved
Now in MMBE unrestricted also 10 in that details Sales reqirements also 10
When we create a next sales order no 2 system tells no stock and gives confirmed qty as zero which is fine (in OVZ9 include sales requiremts is ticked and hence system reserves stocks for order no 1 and says 0 stocks for order no 2)
Scenario 2
Plant is 1000 Material is A unrestricted stock is 10
We create a STO for material A for 10 units from this plant 1000 to be sent to another plant 1001
STO created and saved
Now in MMBE unrestricted also 10 in that details Stock trnasport resevation also 10
So as of now the stocks are reserved for that STO
Now if an incoming sales order if comes system allocates these stocks to that sales order which we dont want to happen
In Simple stocks are getting reserved for open sales orders but not for open STOs with availability check in a plant
In OVZ9 in the inward and outward movements tab there is a control box called incl.rel.order.reqs which is set to X and the F1 explanation tells that it will take to STO also into consideration
But actually it is not happening
Include sales requirements is working but not this one
Has anyone undergone this scenario ?
Regards
Raja

Availability check - sales order

Hi experts,
I've gone through the relevant info, but still hit the issue below. Pls help. Thx.
Issue: How to include the created order (not delivered ) when running availability check?
Example:
Stock (storage location C) - 1pc
sales order A - 1pc (confirmed in schedule line)
sales order B - 2pcs (1pc confirmed, 1pc unconfirmed)
Those two orders are created agaisnt storage location C. No other stocks against storage location C are available, such as on-order stock.
In my understanding, order B cannot be confirmed as order A has been created firstly.
Background: As the customer just sells the purchased product, he places PO firstly, then sales order following. Thus, he requests new sales order creation to be based on the stock qty, created sales order qty, PO qty to be received & delivered sales order qty.
For this sales scenario, availability check with ATP is activated, but not against product allocation. And the check boxes "incl.purchase orders", "include sales reqmts", "include deliveries" are checked in OVZ9 only.
ps. "Check sales requirements" has been checked in Availability check control while "No storage location inspection" has not been checked.

Dear Cathy
Can you please reconfirm that the combination of availability check and checking rule in OVZ9 in which, you have selected the box "Include sales reqmts" is the same value what you have maintained in material master MRP3 view for availability check ??
If the availability check is same in both the cases, then try to create a fresh order and post the outcome.
thanks

Sales Order - Availability check for components

Hi All,
I have 2 parts to my qns.
1. When a sales order is created for a component, with a req date, the system checks & informs if the mtl can be provided on the req date & if not proposes a new date - May i know which checking rule is used & also what all does the system check for?
2. A component say 'ABC' is used internally for production purpose & also sold as a spare part. A sales order for this component is created with a req dt. say 1.3.2008. The system commits the stock to the sales order. A production order is created later with a req. dt for 'ABC' say 1.2.2008. So when i carry out a collective availability check for the plant with ATP checking rule & with availability check reset indicator ticked, i believe the system should reset the commitments made to the sales order & assign the stock to the production order, but it is not happening so. Once the commitment is made to the sales order, it is not resetting, how can i change this behaviour?
Await inputs.
Anyone to help on this?
Edited by: Vivek on Jan 15, 2008 10:56 AM

As we know, availability check is controlled by the combination of checking rule and the checking grp.
U can see this at OVZ9 Screen. checking grp is proposed from material master Sales org 2 view or MRP2 views.
In the OVZ9 screen itself, we are setting what are all the stocks the system has to include when doing availability check.
The checking rule specifies the scope of the availability check for the respective transactions in sales and distribution by specifying precisely which stocks, receipt and issue elements should be taken into account during the availability check.
Every checking rule is allocated to a checking group: together these two elements determine the final inspection requirements. In addition, the checking rule includes a specification whether or not an availability check should take into account the replenishment lead time.
Currently, the checking rule is predefined in SD.
while answering to the second question, i think the system carries out the availability check again at the time of delivery, provided u need to maintain the availabililty check indicator at req. class level.
Hope i answers.

Availability check for Make to stock and Make to Order

Dear All,
Client is selling Make to stock and make to Order material.
How and what settings need to do for Avaialbility check.or we can use standard one.
I hope in case of Make to Order availability check may not happen.
Please correct me.
Thanks in advance.
Regards,
Shrikant

hi,
yes for make to order we dont have AvChk. for make to stock items u need to follow the
below configuration.
Availability check
1. Availability check is an integral part of the business process that determines if the required delivery quantity can be met on a required delivery date. For this purpose the system takes into account pre-delivery activities such as scheduling for picking or packing times and the time taken to produce or obtain the material. It also performs several background functions such as Backorder processing, rescheduling and ATP quantities.
2. Backorder processing: processing of a sales order that has not been fully confirmed or not confirmed at a certain delivery date.
3. Rescheduling: is a proposal of how u2013 confirmed quantities already assigned to a sales order can be reassigned to other sales orders that have a higher priority.
4. Available to promise (ATP): is a process of checking the available quantities of a material. The ATP quantity consists of warehouse stock + planned receipts (incoming stock) u2013 planned issues (outgoing stock). to examine stock on hand (CO09) proceed to logistics u2013 sales & distribution u2013 sales u2013 environment u2013 availability overview.
5. Replenishment lead time (RLT): is the time taken for the material to become available either internally (in house production) or externally (from a vendor). The most important things to consider during an external procurement are purchasing and MRP 2 (procurement) views of MMR where the processing time for purchasing, planned delivery time and goods receipt processing time are taken into account. On the other hand internal procurement is based on in house production time (MRP 2 view) goods receipt processing time or alternatively RLT time, which is found on MRP 3 view.
6. RLT (Replenishment Lead Time) is the time taken for the material to become available. RLT is only used when doing an ATP check (Available To Promise). The value of RLT for a material is specified on material master record.
7. There are three types of availability checks u2013
Check on basis of ATP quantities.
Check against product allocation.
Check against planning.
Configuring Availability check through Checking Groups u2013
1. The checking group + checking rule determine how the availability check is to be performed.
2. The checking group determines whether and how the system checks the stock availability and generates requirements for material planning. The checking group defines what type of requirements will be passed on i.e. summarized requirements (daily/weekly) or individual requirements for each sales order.
3. The checking rule applies to how the availability check is to be carried out at the transaction level. Note that you must define checking rules for each individual application such as for production orders for example. In Sales and Distribution, the checking rule is specified internally within the system and cannot be changed.
4. The checking rule, in conjunction with the checking group, determines the scope of the availability check for every business operation; that is, which stocks, receipts and issues are to be included in the availability check and whether the check is to be carried out with or without the replenishment lead time.
5. Briefly explaining the above u2013 checking group determines which type of requirement to be passed on to MRP whether it be individual or summarized and checking rule which is at the transaction level and can be configured independently for each application module, determines which stocks, receipts and issues to be taken into account. For performing an availability check checking group has to work in conjunction with checking rule.
6. Advantages of individual processing over summarized processing u2013
Backorder processing is possible.
You can access (MD04) order, line and schedule line individually which gives a greater control on available stock and requirements placed on stock.
The system automatically uses individual requirements in case of special stock items.
7. Required data for the Availability check to be carried out u2013
The Availability check must be switched on at the requirement class level.
The Availability check must be set at the schedule line level.
A requirements type must exist by which the requirements class can be found.
A plant must be defined in the sales order for each schedule line item (in other words plant must be defined for every material in MMR).
A checking group must be defined in the material master record in the MRP3 screen in the availability check field.
8. Configuring Availability check and defining Checking Groups u2013
Checking groups are introduced into the sales order based on the setting in the material master record.
SAP standard checking groups are 01 u2013 summarized requirements and 02 u2013 individual requirements or you can create your own by copying the standard ones.
Total sales and total deliveries columns are there to configure a checking rule to sum up requirements to post to MRP either individually or by day or week.
Block quantity required can be set if you want several users to be able to process the material simultaneously in different transactions without blocking each other.
The no check indicator is CHECKED when you DO NOT want the system to carry out ATP check.
9. Defining material block for other users u2013 the block check box is an indicator that enables you to block material master records of a particular material during the availability check and restrict other users from accessing same master record and reserve the material. If the block is not set, two users can confirm the same material at the same time for two different orders, not knowing if the stock is available or not. If you select this field, the material is blocked during the availability check and other users cannot: a) Make changes in the material master record. b) Create purchase orders for the material. C) Create orders for the material.
10. Defining default values for checking groups - Checking groups are introduced into the sales order based on the setting in the material master record.
However if there is no entry present in the material master record for the checking group, a default value can be set here, depending on material type and plant.
This default value will be used by the system depending on the material type mentioned in MMR and plant in sales order.
If an entry exists, this default value is over written by MMR.
11. Controlling Availability Check u2013 in this section, you tell the system what stock on hand and what inward and outward movements of stock it must take into account when performing the availability check in addition to whether or not to consider the replenishment lead time.
12. These settings are based on the checking group that is assigned to the material master record and the checking rule that is predefined and assigned to the sales and distribution transaction.
13. These settings carry out control both for sales order and delivery as well. This is due to the fact that you may want to include specific stock or incoming stock for the sales order, yet at the time of the delivery only include physical stock on hand waiting to be shipped.
14. It is possible to indicate to the system that you would like the availability check NOT TO CHECK the stock at the storage location level. This indicator is used to set the scope of the availability check.
15. It is used to switch off the check at storage location level. You create a reservation for a particular storage location. However, the scope of the availability check is set in such a way as to exclude the storage location. In this case, the system carries out the check at plant level only and does not take the storage location into account that is specified in the reservation.
16. Should you not want the system to automatically check RLT, you may indicate so here. RLT is the time taken for a material to become available. It is only used when doing an ATP check and is taken from MMR.
17. Defining the elements in the availability check entirely depends on the business needs, but a few tips are given under u2013
When controlling the Availability check at the time of the sales order, a purchase requisition does not necessarily indicate by it is going to come into the plant.
A shipping notification on the other hand - a confirmed purchase order u2013 is a good indicator of receiving stock on a specified date.
It is always recommended not to select the shipping notifications for the delivery requirements type as you may not actually receive the stock into plant or warehouse for which you are creating a delivery.

Work Order Material Availability Check Customizing

Hi,
I am currently trying to set up material availability check in the work order before saving. I am testing it by entering a material in the work order for which there is zero stock. Then clicking on ORDER > FUNCTIONS > AVAILABILITY > CHECK STOCK MATERIAL. However SAP would return 'All checked materials in order 100000317 are available' in status bar.
My customizing is as follows:
Define Checking Rules (SPRO):
PM     Checking rule for plant maintenance
Define Scope of Check (OPJJ):
   Availability Check: 01 (Daily Requirements)
   Checking Rule: PM (Checking rule for plant maintenance)
   Availability check: 2 (Check availability during order release)
    Stocks
    Include safety stock: X
    StockIn Transfer: X
    Incl. quality insp. stock: X
    Replenishment lead time
    Check without RLT: X
    In/outward movement
    Incl. purchase orders: X
    Incl. purchase requisitions: X
    Incl. dependant reqs: X
    Include reservations: X
    Include sales reqmts: X
    Include deliveries: X
    Incl. planned orders: X (check all planned o)
    Incl. production orders: X (take all production)
Define Scope of Check (OIOI):
   Plant: (Corresponds to Work Order)
   Order Type: (Corresponds to Work Order)
   Check material availability when saving order: X
   Check rule: 02 (Corresponds to material being used)
   Release Material: 3 (No release if parts are missing)
   PRT Availability: No check
   Capacity Availability: No check
I would appreciate if you could indicate if I am missing something in the customizing or if there is some sort of error. I would like SAP to display a system message on the status bar stating that this material is not available once the user enters this material.
Regards,
Nikolai

I'am facing the almost the same problem. Could anyone tell me:
1. How to make material availability check work during Work Order creation?
My requirement is Work Order can not be created when it has missing parts. I have set the config to '3' can not created when is has missing parts, but it still does not work.
I have implemented SAP Notes 1148139 on my system (SAP ECC 6 Ehp 5) also, but still does not have any effect.
I must not set the config Res./Purch Doc creation to 'immediately', because it does not fit to my user requirement. Is there anyone knows how to solve this requirement?
2. How to make information message/ Availability check screen appear when sparepart is missing, without clicking Availability Check button? for example: appear when clicking Save button.
Thank you

Availability check of sales order in planning strategy 40

Dear friends,
Kindly help me this query:
From online SAP help in Demand Management, it said in planning strategy 40:
"An accurate availability check is performed according to ATP (available to promise) logic during sales order processing. The system checks whether sufficient planned independent requirements have been planned to cover the sales order.... If there is insufficient coverage of components (the sales order quantities exceed the planned independent requirement quantities), the sales orders cannot be confirmed"
According to above paragraph, I think that availability check of sales order is carried out against PIR, if PIR quantity cannot cover sales order quantity then order will not be confirmed, it also means stock on-hand will not be included in availability check. However, my testing reveal a different conclusion: sales order is confirmed against stock on-hand, not PIR. My questions are:
1/ in planning strategy 40, how does system carry out availability check for sales order?
2/ how to interpret above help from SAP?
I got that help from this link: http://help.sap.com/saphelp_erp60_sp/helpdata/en/cb/7f9b7043b711d189410000e829fbbd/frameset.htm
Many thanks for your clear answers.
Regards,
Duc.

Dear duc pb ,
In 40 its only ATP that works.
you can do another test ,
Create PIR 15 quantity.
Create a stock of 10 quantity.
and now create a sales order firszt of quantity 30, as both of the above after combining cant fullfill this demand, save order run MRP.
system will create orders against PIR (15) and remainibnbg quantity of sales order (5)
run one more test, by creating PIR 15 quantity , no stock and a sales order of with quantity 10.
share your findings.
Thanks
Ritesh
