Critical Issue: Availabilty check & alternative BOM selction issue

During the upgradation project I'm working facing the following critical issues:
1)While creating the sales order, system carries out the availability check in APO.In material master checking group Z5 is defined.
 Actually I want to know hw the system carries out the search in APO & what are the settings in R/3 or APO we have to make?
2)Suppose there are 3 alternative BOM's of a finished product.A requirement is while creating the sales order availabilty check should be carried out & system should check the availability of components on the required date.If the component is not avalable system should go & check the second alternative...third alternative until it gets the confirmation of component availability.
 How we can set this functionality & what are the prerequisites or customisation settings we needs to make?
 Would appreciate providing your inputs on this critical issue.
Thanks,
Nilesh

Before you understand how the APO Availability Checking concept works, I would suggest you understand about the regular R3 availability checking. As this is the core for the SD and APO GATP. Refer help.sap.com
Question 1:
Settings in R3: You have the ATP integration model in CFM1 transaction. You need to activate this just one time and never again. what this does is basically transfer all your availability checking customizing to APO.
All the settings for the Availability Checking group ( Z5, etc) are already maintained in R3 and they get transferred to APO by the integration model. You donot need to anything else.
Settings in APO:
If you are using Product Allocation Concept, You have to maintain the Check Instructions.... Otherwise there are no other settings in APO
Availability Check in APO :
( see the following blog for the requirements class( Name in R3) or check mode( Name in APO) determination http://solution-timezone-issue.blogspot.com/ )
The check mode and the business event( These are hardcode internally in R3 - For SD- A) are determined from the order and based on this in APO it follows the following order
(1) Reads the check instructions settings in APO
For example say the following have been determined from the SD Order : Check Mode 041 and Business Event A
Say we have maintained in APO that the first step is Availability Check and all the other two steps we havent maintained or left blank ( Product Allocation and Forecast)
Look for the customizing in APO
SPRO>APO>GATP>General Settings>Maintain Check Instructions ****
(2) Carries out availability Checking same as in R3 and no different
From the masterial master considers the availability checking group ( Ex: Z1) and the business event( SD transactions- A)
Very Important and the core of availability checking which is similar in R3 and APO***
Against these 2 combinations, the settings are checked which define what stock and in/outward movements are to be considered during the availability check
For customzing settings in APO
SPRO>APO>GATP>Maintain Check Control>
For Customizing in R3
SPRO>Sales and Distribution>Basic Functions>Availability Check and transfer of requirements>Availability check with ATP logic or planning>Carry out control for availability check
This is the answer to your first question.
Your second question would need some time and I will try to answer it as well.
Hope this helps you..

Subcontract PO item withdrawal issue when alternative BOM item used

Hi,
As title mentioned, when we issue alternative material for a subcontract PO in BOM, but it still shows the quantity from primary item.
(For example, we have a product, let's say it as Product-A, it's combined by material-B1 and Material-C1
And the BOM for Product-A for item material-B1 has an alternative item, material-B2
Now the issue is when we issue material-B2 instead B1, but the PO usage/withdrawal listed in B1)
Because we are making a list for China custom for material usage, the issue listed above makes our list not available for custom department.
Please let us know how we could make the withdrawal in PO shows B2.
thanks,
Steven

Dear Steven,
As explained by our forum friend maintain this data.
1.Create 2 different BOM for the same header material with the respective BOM components.
2.Create production version for the header material using T COde MM02--->MRP4 view and click on prod.version,enter the same
as 0001,text as prod version 1,default valid from date will be the current date and the valid to date will be 31.12.9999.
3.Enter the lot size for which this prod version is valid and then in the alternative BOM select the BOM and save the data.
4.Prdo.version can also be maintained through C223.
5.Assign this prod version in the sub-contracting purchase info record in ME11,under prod version under purch org data(not sure
check this alone).
6.Likewise assign the prod version that is linked to the BOM to be picked for each sub-contracting vendor.
Check the results after MRP and revert.

BOM deletion issue

Hello all,
I have an issue with BOM deletion.User has used alt.BOM 2 in a process order,with a production version of 0002.Next day he deleted the alt.BOM 2 and assigned Alt.BOM 1 to production version 0002.Now when i check the process order in master data tab,the BOM is given as alt.BOM 2.But it is not in the system .I tried to check through change number and tables,but could nt get it.
I know if the BOM is deleted with deletion indicator we can archieve that.I think in my case user deleted the same directly from header .
Is there any possibility i can view this deleted BOM 2 if the same has deleted without a deletion indictor?Any tables,transactions,programms available?
Thanks in advance

George

Hi George.
Since the 2nd alternative Bom has been deleted Directly from Header at Cs01, It is also got deleted in Bom table,.
So u cannot get details of deleted one.

Issues while processing the BOMs using fm ''CSAP_MAT_BOM_MAINTAIN'

Hi Group,
we are facing issues while processing the BOMs using the basic type(Z-idoc type) for standard type BOMMAT04.
thing is that the segment 'E1STPOM' is defined to contain 1 to 99999 records in it.
when an Idoc is run(say with 150/200 segments of 'E1STPOM'), there was a standard error with error message id PIC01(number : 004) when the Idoc is processed with the Standard function module 'CSAP_MAT_BOM_MAINTAIN'.
the error says 'Error reading material FING_005 . Exception: 0' and Check whether the material number is blocked. but when checked, the Material seems not blocked.
kindly advise how to overcome this error and proceed further.

Checj the material status, while its transfer from one server to another server the status should be different

Creating refunds in CR&B and issuing the check in Accounts Payable (ERP)

Hi experts-
I'm on an implementation project where ERP and CR&B are being put in place, both being on the same SAP instance/ box. The current refund process calls for generating refunds on the customers' contract accounts in CR&B and issuing the checks out of AP. The check memo field is to include the customer's name, Contract Account # ,and service address.
Is there a standard SAP process to accommodate for this requirement? If not, what custom program or interface could satisfy the requirement?
I'd like to hear if anyone has done anything similar and what successful approach was followed.
Thanks,
MD

1. Take List of all applied Invoices of the Payment
2. Check the status of those invoices. Each one of them should be in status 'Accounted'
3. If not,Identify the problem with the Invoice and Clear that. The problem may be Invoice adjustment(adj to Paid invoices allowed).
4. Try running Create Accounting again.
5. If the problem persists still, it conveys us that the Transactions were struck in loop and can be resolved only by using UPDATE command.

Issue with check generation in Automatic Payment Program

Hi experts,
I need your inputs for an issue with check generation in Automatic Payment Program. Trying to make a payment to a US vendor with payment method C. The due item is getting picked up and a clearing document is getting generated. But Check is not being generated, niether can I see an entry in PAYR table. However, if I try to generate a check manually in FCH5 for the same clearing document, it is working.

Have u checked the Variant created in F110 - Printout / data medium, whether the Hose bank details are correctly set or not.
If yes, check the Printer details
Let us know the results
Thanks

Re-issue voided checks with same check number

Hi All,
We accidentally voided a check which has already been received by the vendor. We want to re-issue the check in our system, but it wont reconcile as the check numbers are different. Is it possible to change the check number?
Regards,
Pooja

Hi Pooja
Lets assume that the cheque numbers that were voided were from 10001 to 10521. So create a payment document against the same bank account which was used earlier and assign the document numbers 10001 to 10521. Now again create a new payment batch with the same set of parameters as provided previously. Ensure that the same invoices are selected by the batch (no less or more). Now submit the batch. This way the system should assign the same cheque number to the supplier sites which were issued previously. So if a supplier was issued 10002 cheque number with an amount of $1000 previosuly, then this batch should also issue the same cheque number for the same amount against that supplier. Please ensure that the system is bahving in the same way as thought. Else you might have to generate manual payments for each of these 521 payments :(.
In this way, you will not be required to do any swapping or run any custom script. While reconciling, you will match the bank payments with this new payments.
Hope this clarifies.

How to solve the issue "CUV check user equivalence failed" ?

Folks,
Hello. I am installing Oracle 11gR2 RAC using 2 VMs (rac1 and rac2) whose OS are Oracle Linux 5.6 in VMPlayer according to the website http://appsdbaworkshop.blogspot.com/2011/10/11gr2-rac-on-linux-56-using-vmware.html
In order to install Grid Infrastructure, we need to run Cluster Utility Verification (CUV) at first by running the cammand below:
[ora11g@rac1 grid]$ ./runcluvfy.sh stage -pre crsinst -n rac1,rac2 -verbose
Its output:
Performing pre-checks for cluster services setup
Check: User equivalence for user “ora11g”

rac1 failed
rac2 failed
Result: PRVF-4007 : User equivalence check failed for user “ora11g”
ERROR:

Verification cannot proceed
Pre-check for cluster services setup was unsuccessful on all the nodes.
As you see above, check user equivalence failed. I have run the 4 commands to fix this error as below:
[ora11g@rac1 /]$ ssh-keygen
Its output:

Its output is the same:
PRVF-4007 : User equivalence check failed for user “ora11g”

I think the problem is "Broken pipe" and ssh cannot write authorized_keys to the machines.
My question is:
Do any folk understand how to solve the issue CUV "check user equivalence failed" for 2 VMs ?
Thanks.

Folks,
Hello. Thanks a lot for replying.
I have installed Grid Infrastructure a few times. Each time, on step 7 of 9, the installer fixes and checks 2 machines correctly. The entire installation has 3 parts as below:
1) Install Grid Infrastructure for a Cluster
2) Execute Root Scripts for Install Grid Infrastructure for a Cluster (script is root.sh)
3) Configure Oracle Grid Infrastructure for a Cluster that includes NCA, ASMCA, PICA and CVU.
Each time, on step 8 of 9, the Installer installs Grid Infrastructure for a Cluster successfully that includes "Prepare, Copy files, Link binaries, Setup files and Perform remote operations".
But when the Installer get to part 3 CVU, it fails and then the Database cannot be installed.
Deinstall Grid is a very complicated process to do. Because of this reason, we need to run CVU at first to make sure everything is correct for 2 machines before install Grid.
Even we ignore "user equivalence (ssh)", we don't know whether other items can be passed or not because CVU cannot proceed to check the machines.
My question is:
How to have the script "runcluvfy.sh" continue to check the machines while confronting "user equivalence failed" ?

10.4.10 Audio Popping Issues: Information Check with Internal Speakers

For people with internal speakers, or those without subwoofers: Please read all the way to the bottom to find a test that will determine whether you are also having audio problems, even if you can't hear pops.
We've had a lot of discussion about audio popping due to 10.4.10, and the evidence indicates that the audio circuitry is going to sleep to conserve power, even on AC-only computers like the iMac, Mac Mini, and (at least one) Mac Pro. Some people claim to not have this problem, but I'm wondering if they just aren't noticing it.
Having external speakers with a subwoofer, set to high amplification, are key to obvious detection of the problem. Let the sound subsystem go idle for 30+ seconds (wait a minute with no audio, just to be safe), turn up your external speakers really loud, and cause the computer to make a sound. You should hear a burst before the sound plays. If you repeat the sound, you won't hear the burst. This is the sound of the audio circuitry powering on, and the speakers are amplifying it.
About 30 seconds after the sound finishes playing, if you leave the volume of your speakers turned way up, you should hear a "pop" as the circuitry is powered off. Then, playing another sound will recreate the burst.
I haven't been able to hear these sounds with internal speakers, either on the Mini or iMac. But the problem still exists, and it is detectable... if you know what you are looking for.
The burst of the audio circuitry turning on also causes a delay in the audio. The delay is a noticeable fraction of a second, an it can easily be detected if you have a repeatable source of sound. I like Terminal.app, because I use that application all day, every day. Here is how you can check to see if you are also subject to the audio problems:
1. Start Terminal.app (in the /Applications/Utilities directory).
2. Wait one minute for the audio circuitry to shut down.
3. Without typing anything else, very quickly strike and release the Backspace key.
4. If you pressed the key all the way, the program should have caused a beep. However, if the audio circuitry goes to sleep, the beep should occur after you have moved your hand off the key. This is because the circuitry takes time to power itself on before playing the sound.
5. Now, quickly strike the Backspace key again. You should notice that the sound is produced immediately as you hit the key, without the delay you just witnessed.
6. Strike the Backspace key repeatedly, to confirm that there is no audio delay. Do this about once every second or two. If you press the key too rapidly, not all of the presses will produce sounds... this behavior is not related to the issue we are testing.
7. Wait another minute for the audio circuitry to shut down, and strike the Backspace key once more. You should again observe a delay between your strike and the sound production.
If you witness delays like this, your audio circuitry is also going to sleep, and you are having the same audio problems as the rest of us. However, either because you are using internal speakers, or because your external speakers don't have the appropriate response, you aren't hearing the same bursts and pops as the rest of us.
Please try this test, and report here. I want to build a list of people who previously couldn't hear the sounds, but still have the delay. This might give us a better picture of the scope of the problem.

Re: 10.4.10 Audio Popping Issues: Information Check with Internal Speakers
Your analysis of what is happening is right on.
The problem on my Intel Mac mini with external Klipsch speakers (two mid-range/high and a subwoofer) is REAL obvious as the system emits a hum like a Spinal Tap amplifier turned up to #11 when 10.4.10 powers down the audio circuitry
Then, if I play a song in iTunes, it first pops and the hum disappears right before playing.
Quite annoying.
Here's what I sent to Apple tech support:
Guys/Gals (OS X Engineers):
Concerning the Snap, Crackle Pop Audio problem in the 10.4.10 update:
Please. Just do the right thing and fix the audio.
There is no need to power cycle the audio subsystem to save .0005 amps on your laptops.
And then to make your Mac mini/iMac/other desktop users have to put up with it when using AC power is ridiculous.
Put the audio subsystem back like it was in 10.4.9 and let the laptop battery freaks looking for mini-amp savings get a "work-a-round".
Crikey!

Is there a Pages for MAC OS 10.7.x? If not, what is the alternative? Concrete issue is that I have received a .pages document and need to edit. Many thanks

Is there a Pages for MAC OS 10.7.x?
If not, what is the alternative?
Concrete issue is that I have received a ".pages" document and need to edit. I am running Mac Pro with OS X 10.7.
Many thanks

It is important that you determine if the .pages document originated from Pages ’08, Pages ’09, Pages v1.7.2 (IOS 6), or was exported as Pages ’09 from Pages v5+ on OS X Mavericks. If it meets one of these criteria, then you can edit the .pages document on your Lion machine with Pages ’09 from the iWork ’09 DVD. Pages documents can not be opened with TextEdit, but can be viewed with Preview.
On the otherhand, if the .pages document was created with Pages for iCloud beta, Pages v2.2.1 (IOS 7), or Pages v5+ on Mavericks, then your only recourse is to edit the document with Pages for iCloud beta. Since Fall 2013, Apple changed the .pages document format into something even more malevolently proprietary. Apple word processing products since this timeframe, are subsets of the Pages ’09 features/functionality, and will filter out content they do not support.
A Pages ’09 document is usually a compressed (zip) folder archive that looks like a regular file to the Finder. The newer Pages family of products only write out a package that to the Finder, also appears to be a regular file, but in reality it is a folder. The newer Pages documents must be zipped before placed on non-Apple filesystems.

In Tr-CD:ltr , how can I check the datail of issue ?

Hi expert,
I want to know how can I check the datail of issue in Tr-CD:ltr ?
When I click the bottun "check status" , some messages are appeared .
But that messages does not show the datail of issue.
For example ;
"Issues detected regarding statistical information" .
"Issues detected regarding the load jobs"
"Issues detected in schema XXXXXX"
How can I check the datail of issue?
Thanks in advance .

Hi Raj,
Thank you for reply.
And thank you for your advice.
I have one more question.
When the message's status is warning in ltr , are no masseges appeared in sm21 & st22 ?
I clicked the bottun "check status" in ltr , some messages were appeared.

Goods issue quantity check

Hi Friends
Scenario: There are 2 components with quanity of 100 each for header material (10 qty) .Both teh components have backflush indicator.
User iwants option of doing Goods issue through MB1A also.Suppose 20 qty each is issued through MB1a by using Mvmt type 261 ,the reamining qty that needs to be issued is 90 each.(reservation is not reduced )
When user does confirmation of order by CORK for 10 quantites the quanity that comes in Goods movement overview is 100 qty.
Why the quantity that si already issued is not taken into account.?

Sachin,
As you said you have set the backflush indicators for both the components. Then if you try to issue the components with MIGO or etc system will issue error message 'Documents contain no selectable items.' if the order contains these two components only.
So it's clear that the GI against the order with t code MB1A is not against the reservation created by the system & will be treated as unplanned goods issue.
That is the reason system proposes the whole quantity while confirmation.
Also if you set BF indicator then you can not issue & you are not supposed to issue the component without confirmation. There is no exception
Hope this helps you.

1. Get BOM number from MAST
2. Get alternative BOMs for above BOM nos from STKO
3. For all above alternatives fetch item details from STPO.
The issue is when I try fetching BOM details, though i fetch details for alternative 1, I can not fetch details for altenatives 2 , 3 and so on. I could not find link in STPO to fetch details for other alternative as alternate BOM field not available in STPO.
Can anyone help on this issue. Thanks in advance.

Availabilty check & tor

Hi sd gurus,
can anyone plz send me screen shots for availabilty check and tor in sd point of view ,plz help me am having the theory part idea but am not geting complete picture plz send me

Hello Srinu,
I cant provide you any screen shots for the topics you have asked. But pls go through the following notes. Its really good and you'll have a clear Picture on the topics.
 Availability check is considered as a pre-sale activity, where as TOR and MRP are post sale activities.
Materials Requirements Planning (MRP) and Transfer of Requirements (TOR).
1. A schedule line in a sales order represents the customers intended delivery date and quantity to be delivered. In a standard sales order processing, the system transfers requirements (TOR) to Material Requirement Planning (MRP).
2. MRP - then determines if there is enough quantity of stock available for the scheduled delivery date. The TOR aims to ensure that the materials ordered are ready for the requested delivery date.
3. The TOR is closely integrated to Materials Management and Production Planning modules thus it must be configured in association with the respective teams.
4. The TOR can be set either for individual requirements or for collective requirements in MMR (Sales: general/plant and MRP3 views).
5. Individual requirements are the transference of requirement to MRP for each schedule line of the sales order. An advantage of this is that the availability overview (CO09 logistics material management environment stock availability overview) will show the order quantity, sales document number, item number and requirements class for each schedule line for which a demand has been created.
6. Collective requirements are a collective grouping of requirements created either daily or weekly that are transferred to MRP; but the documents processed in collective requirements cannot be individually identified from the availability overview (CO09). Collective requirements are useful to a business that deals with a large volume of sales orders per day, as it allows the business to have a clearer view of the availability overview and speeds up the response time within the system as well.
7. The system will automatically create individual requirements (irrespective of the collective requirements indicated in MMR) in case of special stock items such as consignment, returnable packaging, make to order stock etc.
8. The control elements that are used for Transfer of Requirements (TOR) and Availability Check are
 the requirements class
 the requirements type
 the checking group
 the schedule line category
9. The requirements class is the controlling factor for TOR and the availability check for all sales document types. It determines if the system has to perform TOR, Availability check and product allocation to any particular sales order.
10. The requirements class is determined from the requirements type of the material.
11. The checking group in general is the criterion that groups together all the checking rules from all application areas for a material. In conjunction with the checking rule, it defines the scope of the availability check for each business event; that is, which stocks, goods receipts and goods issues are taken into account in the availability check, and whether replenishment lead time is checked. The checking group must be defined and allocated to the material master record in the sales: general/plant view in the availability check field.
12. for TOR to be carried out, you need to ensure the following criteria are met
 The TOR must be switched on at the requirements class level.
 The schedule line category must be switched on for the TOR (fine tuning).
 A plant must be assigned to the sales document line item level.
 A checking group must be defined and allocated to the material master record in the sales: general/plant view in the availability check field.
Planning materials
 It is possible to create a common planning material and assign similar materials to it (MRP 3).Independent requirements are created for the planning material to cover the requirements that are expected for the materials assigned to the planning material. This means that you do not have to create independent requirements for each material. Instead create a material and assign the same to the planning material already created with similar properties.
 A valid material master record must exist for the planning material in the planning plant. The material master record of the planning material cannot contain a planning material as this procedure can only be carried out at single-level.
 An appropriate strategy group must also be entered in the MRP 3 screen for planning with planning materials. The strategy group groups all the planning strategies that can be used for a particular material. The planning strategy represents the procedure used for planning a material and is (technically speaking) controlled by the MRP types.
 Consumption mode defines whether and in which direction on the time axis from the requirements date (corresponds to the date when the sales order items were created) the consumption of customer requirements with planned independent requirements should occur. Consumption period must exit between 1 and 999 days.
 Backward consumption only: starting from the requirements date, backward consumption is carried out within the relevant consumption period specified in MMR i.e. the system reduces the planned independent requirements that lie in the past. Likewise forward consumption only represents starting from the requirements date, the system reduces the independent requirements that lie in the future within the consumption period.
 Backward/forward consumption: in this case backward consumption is performed first and forward consumption is performed later depending on the availability of the independent requirements in the past. Forward/backward consumption is vice-versa of the above.
Stock requirements list
1. Stock requirements list is the central table for planning and stock control. It is invaluable to the interpretation of the available stock and the situation of stock levels in a plant.
2. Menu path: MD04 logistics material management inventory management environment stock stock requirements list. Here you can see the order number or delivery number as well as the line item and schedule line placing the demand on the given plant. It also shows the required and available quantity of material per order.
3. Another view of the stock situation in plant can be obtained from MMBE (stock overview). This view will show you total stock per company code, then at the plant, storage location and at batch level.
4. A useful tool in MMBE is material movements, which can be viewed by selecting stock line and proceeding to environment, material movements.
Configuring Transfer of Requirements 
1. IMG sales & distribution basic functions availability check & TOR transfer of requirements define requirements classes.
2. Requirements class (OVZG) is the controlling factor for the availability check and TOR for all sales documents. It determines whether the system should perform the transfer of requirements, availability check and product allocation when a sales order is created.
3. The system uses the entries used at this level as default and brings the data into the sales order. The same entries made at the schedule line category level (VOV6) are only used to fine tune the entries previously made at the requirements class level. The standard requirement class is 041 (order/delivery requirement).
4. Requirements type (OVZH) (displayed in the sales order beside schedule line category) requirements types identify the different requirements, such as sales order requirements, delivery requirements or individual customer requirements. The requirements types can be changed, for example, in order to represent customer-specific terms.
5. The first step in the process of configuring TOR is to define a requirements class (041 standard) by copying the standard one. It contains the preconditions for performing availability check, TOR and product allocation.
6. Next step is to create a requirements type, which is based on item category and MRP type of the material and allocate the previously defined requirements class to it. A requirements class can be allocated to more than one requirements type. It is possible to change the requirements type manually at the time of creating the sales order.
7. MRP type in the MMR determines how a material is planned for requirements i.e. automatic reorder point planning, manual reorder point planning or forecast based planning.
8. Determination of requirements types using transaction: when a sales order is created, the system looks for a relevant requirement type by using its own search strategy. Either it uses the following search strategy or you can make the system skip this entire process and straight away search for item category and MRP type by selecting 1 in the Q field while configuring determination of requirements types using transaction.
9. First attempt is to find the requirements type using strategy group in MMR.
10. If strategy group is not found, it will look for MRP group (MRP group groups together material with similar planning requirements and allocates special control parameters for planning such as strategy group, planning horizon and the creation indicator for planning run.
11. If MRP group is not found, it will try to access MRP type.
12. If no requirements type is found using MRP type, the system will use material type when accessing the corresponding tables.
13. Failing to find the requirements type even at this stage, it will try to get the requirements type using the item category and MRP type.
14. If this doesnt work either, then it will try to determine requirements type using only item category.
15. If the last attempt fails, the system determines the transaction is not relevant for availability check or transfer of requirements.
16. As discussed earlier TOR and availability check are fine tuned at the item category level. This is done at this stage i.e. define procedure for each schedule line category as a next step.
17. Block quantity confirmation in delivery blocks (linked to VD05 customer block): in the standard sales order processing, the system transfers the requirements to MRP, but in some cases you may need to block a transaction due to a bad result of the credit check.
18. When requirements are transferred to MRP, the confirmed quantity is also reserved for confirmed sales documents . If a transaction is blocked for delivery, the required stock will be blocked so it cannot be used elsewhere. To prevent this, you can block the transfer of requirements for a delivery block in this step.
19. You can set a limit on the number of days you would want the system to postpone this block on confirmation of requirements. This can be done by setting the number of days to the block in the Def. period column.
20. Maintain requirements for TOR: can be used to determine that the TOR to MRP is not carried out unless a number of conditions are met. For example in a standard sales order processing, a purchase order may need to be created in order to meet the demands of the customer. This purchase order is used to purchase new stock in order to meet the demand on MRP for particular customers sales order. Here you define requirements that must be met in order for the purchase order or assembly order to be created.
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 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) planned issues (outgoing stock). to examine stock on hand (CO09) proceed to logistics sales & distribution sales environment 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
 Check on basis of ATP quantities.
 Check against product allocation.
 Check against planning.
Configuring Availability check through Checking Groups
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 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
 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
 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
 Checking groups are introduced into the sales order based on the setting in the material master record.
 SAP standard checking groups are 01 summarized requirements and 02 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 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 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
 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 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.

SFG alternative BOM in Different BOM

Hi all ,
I have one SFG which is having two alternative bom .
This SFG is used in 2 finished material BOM .
In FG material- 1 i want use SFG alternative -1 and
in FG material -2 i want to use SFG alternative -2 ,
when I RUN mrp system should select the relevant boms.
Is it possible , If yes how to do?
Thanks ,
Regards ,
Ganesh

Dear ,
Are you running MRP at a time for FG1 and FG2 ?
Basically , I am looking for an work around like this :
1.FG1 BOM Alternative : SFG1 as Component -Keep BOM Status -1 Active , SFG1 BOM Alternative 1 : X, Y as component -Keep BOM Status -1 -Active
2.Keep FG2 and SFG2 BOM In -active -2 in CS02
3.Create Routing of FG1 and SFG1 with the same manner .
4.Run MRP-MD02-FG1-Check MD4C-Convert SFG1 planned Order to Production Ordre and also FG1 -Planned Oder to Production Order .
5.Repeate the the Same for FG2 and SFG2 keeping FG1 and SFG2 as inactive BOM status -2 and susequently convert the same .
This is may the work around .
But standard procedure is that , you need to go for Aleter native BOM selection in two fold (FG and SFG for both ) based on the Following set up
1.MRP4 -BOM Selction Method -Keep 2/3 SELECTION by PV
2.Maintain two different PV1/PV2 with a lot size and validity in FG and SFG
Now , when MRP will run in FG and explode the BOM at FG, SFG level , it will chek the MRP4 view indicator frist , if it 2 then it will go to PV 1 and PV2 check the Lot size and Validity and select the alternaitve BOM in two fold
Lastly , Implement the BAdI MD_MODIFY_PRODVERS.
Use the method MODIFY_PRODUCTION_VERSION to write your logic (for checking the stocks) and change the production version to
Hope it clarifies your doubt
