ATP and reservation of material quantity

Dear Gurus,
I am trying to configure ATP and find that when i create a sales order using a material that is not batch managed the correct message fires to let me know how much material is present and how much i can have. If i accept the proposed quantity and then make a second sales order for the same material the system lets me know that i cannot have any of the material, this being because the material quanity would already be reserved by the previous sales order. this is how i would like it to work but when i use a batch managed material the reserved effect is lost, i get the message telling me how much of the product is available but the quantity once accepted in the order is not reserved.
How can i solve this problem and can anyone send detailed instructions giving an example?
regards,
Ottley

MRP and Reservation issue

Dear Gurus,
Our scenario for chemical industry is MTS with strategy 10.
After MRP run for material 15 Planned orders are generated. After converting planned orders to Process orders are generated on same day 05/01/2012.
But actual production starts earlier on 25/12/2011 when process order date changed to 25/12/2011 and try to do batch determination error occurs as Material not available on 25/12/2011,though enough stock exists.
After TECO (all other 14 process orders) this allow process order to do Batch determination.
Why this error occurs ?
Please guide.

Hi Pert,
The issue is in ATP logic. Please check of you have comsidered the reservation in ATP and also the pal orders and production orders as welll.

How to reserve the material ( Make to Stock) for selective customers?

Dear Friends,
I want to reserve the material which is a Make to Stock for selective customers i.e if the customer base is 100 I want to reserve the certain quantity for 3 customers.
It is a Make to Stock.
Thanks in advance.
Regards,
Shrikant

Dear Friend
First you have to create sales orders for these three customers
There are three ways of doing this
1. T code MB1B use movement type 412 E and input your sales order no
Stocks will be reserved for this order
Your item category should be marked E in special stock indicator
This is the perfect way of doiung it
Suppose if the order gets cancelled stocks can be moved back to unrestricted using T code MB1B use movement type 411 E
2.Create sales order and then delivery and save dont do picking and PGI
Stocks will be reserved for this delivery
3.In t code OVZ9 if you have ticked include sales requirements then for whatever sales orders created stocks will be reserved for them
But this is soft way of handling as thro backorder processing the stocks can be allocated to other orders

Hi all,
I am facing with and issue related to Reservation.
Problem Defination.
In the Material document List for a particualar MAterial i am able to see the Reservation no.
i.e a material has been issued against a reservation so material document is created and in mateiral document in reservation tab i am able to see the reservation no also.But when i am double clicking on that reservation ,it is taking me to display reservation where i am getting message
=================================================
Reservation 0000022986 does not exist
Message no. M7520
Diagnosis
The reservation you entered does not exist in the data base.
Procedure
Make sure your entries are correct.
Choose the input help in the "Reservation" field to search for a reservation for a material or an account assignment.
============================
It has to be noted that in the reservation tab in the material document .
The requirement quantiy is " 0 "
Withdrawal Quantity is " 0"
Whereas the Material document which has been posted against the reservation is for 10 quantity.
the requirement quantiy should have been 10 and withdrawal quantity should have been 10 because the reservation i have made is of 10 quantity.
I have checked the reservation list ,the reservation is not there too.
Please help me on this issue
Thanks and Regards

Inconsistency between ATP and ASCP

Thanks for looking at this message. Bit lengthy but will be interesting :-)
In our implementation we use ATP based on planning output and its a constrained ASCP plan (ECC) .
Assuming that sale sorders are available in the system and they have been entered say last month/ or even few months before with request date as the sale order entry date . We did nt have onhand at the time due to which the promise dates have been Sep-09.
Assume that we have made a receipt from supplier/or there is PO in receiving (considered as available date of today by ATP) . In this situation in case a new sales order is entered today with request date of today provided the onhand or expected receipt today is more than sales order qty , the promise date upon sales order entry is today. We do OM loopback and send back sch ship date from ASCP which gives correct dates (Sep or Oct based on lead times). But issue is in the promise date .
Issue 1: customer is questioning while there are so many existing sales orders which are already in arrears and their request dates are all in past months why does a new sales order get a promise date of today?
When ASCP runs overnight it plans based on request date and the onhand/exp receipt is pegged to earliest sales order and not the new one put in today(which is fine and as expected) , but due to the mismatch between ATP and ASCP always there is going to be mismatch in meeting promise date and Sales performance measures go for a task.
Also there all the customers are sent Order Acknowledgement (emailed upon booking order) based on the wrong promise date which causes lot of issues in explaining to each customer.
Issue 2:lets say onhand is 2 and there are 2 sales order lines one for qty 8 (req date 21-jul) and other for qty 2 (req date 23-jul) . I schedule order line 8 (req date 21-jul) first then ATP promises line after LT (say Sep-09) and the qty 2 line is promised today but when ASCP is scheduling it has ability to see request date due to which it can peg 2 onhand to earlier request date and then wait for new supply till Sep-09. The one with later request date will show ship date in Sep-09.
Have attached the screen shots explaining the issue 1 and 2
Best regards
Vinay

Hi Vinayak
Both of your observations are correct. As I managed ATP development for several years, let me help explain these things to you:
1. For 1st issue, where a new incoming sales order can get better date than earlier promised sales order, please understand that ATP is based on supply/demand picture at a point in time when SO was originally processed. If supply/demand picture has changed significantly, you need to use a tool like Oracle Backlog WB to manage and re-process currently scheduled SO to re-assess where they should be promised. Once Sales Order is promised, ATP uses schedule ship date to see when material is needed and uses a supply closes to ship date (JIT). If earlier supplies are available, they're up for grabs by new SO.
Thus, the behavior is working as designed and you need to develop your business process to ensure that backlog management is practiced on a regular basis to avoid such issues.
2. For 2nd issue where you see that ATP isn't using supply to satisfy smaller qty sales order, please understand that ATP is "First-come-First-Serve" and it is working on 1 specific order at a time. When initial order of qty=8 came in, it had no way to know what lies in future or if another SO with qty=2 will come later. Compare this with ASCP which is working a complete set of supplies and demands and can analyze this picture in totality.
I'm sure you'll like your ATP request to come back in few seconds (or may be a min or so) and not take a few hours while you enjoy the hourglass on your screen. No surprise that ASCP plan run takes few hours since it needs to go thru such hoops and try to optimize across these ideas while ATP is a quick answer as what can be done for this in-coming demand considering everything else in the system is frozen.
Please note ATP and ASCP plan serve very different purpose and business process needs to be enahnced to take advantage of best of both these tools.
Please feel free to contact me directly for any further issues in this respect.

Questions on Rules-Based ATP and Purchase Requisitions for STOs

Hello experts,
We are working on rules-based ATP configuration and have several questions about the functionality. Iu2019m hoping that some of you are using this functionality and can help give us direction.
In our environment we have multiple distribution centers and multiple manufacturing plants. We want to confirm sales orders against stock and production orders in any of those plants, depending on the locations that have stock or planned production. For example, we will place a sales order against plant A. If there is not enough stock in plant A then rules-based ATP will use location determination to check in plant B, then C. The scope of check on the ATP check will include stock and released production orders. We will configure plant A as the u201Cconsolidation locationu201D so if stock is found in plants B or C then stock transport orders will automatically be created to move the stock to plant A before shipping to the customer.
We have configured rules-based ATP and this functionality is working well in our Development system. The ATP check is executed and uses the rules-based ATP to find eligible stock in other plants. The system is also creating purchase requisitions to move the stock to the consolidation plant.
Our first concern is that there doesnu2019t appear to be any firm linkage between the sales order and the resulting purchase requisition. For example, if we create sales order 123 for plant A and the rules-based ATP finds stock in plant B it automatically creates a purchase requisition 987 to move the stock from plant B to plant A. However, there doesnu2019t appear to be a linkage between sales order 123 and purchase requisition 987. For instance, if we delete sales order 123 the purchase requisition doesnu2019t get deleted.
Our second concern is that the quantity on the purchase requisition can still be confirmed against later sales orders. For example, say the above scenario resulted in a purchase requisition 987 that consumed all the stock available in plant B. We then create a second sales order 456 for the same product. Plant A is out of stock so the rules-based ATP looks in plant B. We would expect that plant B would also not have any stock because itu2019s all been consumed by the purchase requisition. Instead, the system creates a second purchase requisition to move quantity from plant B to plant A. Itu2019s as if the system doesnu2019t realize that the purchase requisition 987 is already planning to move stock out of plant B.
Does anyone have any thoughts or suggestions on these two scenarios? Is there a way to configure the system so there is a hard linkage between the sales order and the purchase requisition so that if the sales order is deleted then the purchase requisition is also deleted? Should ATP realize that purchase orders are consuming inventory and not allow later sales orders to confirm against that same inventory? Any advice or experience would be greatly appreciated.
Thanks,

Hi,
The scheduling is done in SCM, and from there, whenever the RBA is triggered, the calculation is done always with the old route in SCM. Until you get back to R/3 this is when your route is determined. But the ATP check is always with the original route. So the idea would be that you change the values of the route while still in APO, this is possible via the user exit. Should be done in scheduling in APO.
Hope this information is helpful.

Batch determination issue in process order Material quantity calculation

Dear Gurus,
We are facing issue in auto batch determination in process order (Material quantity calculation ).
eg Material X is active material 200 KIA used in BOM as
10 X   200 KIA
20 Y   10           Filler
30 Z
40 X   200 KIA
50 Y
60 Z
We select line item 10 and 40 and do Batch determination system proposes 2 batches for line item 10 as Batch A and B
and for line 40 again Batch A (with 0.01 KIA) and batch B proposed which is wrong.
For line Item 10 Batch A and B
For line Item 40 Batch B and C or as per FIFO logic.
As Batch A should be consumed in Line item 10 then it proposed Batch B and so on....
We have already maintain data in COB1.
Can any body explain what is wrong in determination.

Material Quantity difference document line item for HU

Dear Experts,
When I try to clear differences in LI21, i get the error message as above.
Error Message : 'Material Quantity difference document line item for HU'
Any idea why this error occurs?
Regards,
Shetty

Hello Shetty,
It may be due to some stock inconsistency. You may try iin case of a non HU managed storage location HU to run LX23 and it can fix discrepancy overwrting MM-IM with LE-WM data. But if it is a HU managed then you can run HUDIFF transaction but only to see if there is stock differences not to fix anything, usually SAP Support (Development Support) does that job.
Have a nice day !!

Tcode-mb24 - Reservations by Material

1) In standard transaction "mb24 - Reservations by Material" .
2) on selection of all the options in the scope of list- open reservations, cancellable reservations, goods mvnt not possible, issues and receipts.
In this report, even if the reservation does not have material it picks the material description from previous line.
Example
Reservation- 907741
item- 1 to 13
it is observed that items numbered 7,8 and 9 have no material, but the description is same as item 6.
I have debugged and found that the problem maybe caused because of the absence of a clear statement in standard program .
Please confirm.
your time and answers will be rewarded with points.

Hi
You are absolutely correct. You do clear the work area or particular field. It will solve your problem.

Contract updation for Delivered material quantity

Hi All,
I have a problem related, contract and release order updating with reference to delivered material quantity.
for example let's say contract is created for 1000 units of material A, after that sales order with reference to contract is created for 500 units and delivery is created for 300 units then remaining order quantity cannot be delivered as customer master is maintained so.
Now I want to create sales order for 700 units of 'A' but system is not allowing to do so saying the 500 units are already referenced.
If i use rejection reason in sales order still system is not allowing to create a new sales order with 700 units.
How to solve this issue?
Please Help
Thanks and regards
Amit

Hi Manam,
thank you very much for your immediate reply.
But the issue is a sales order will have only one delivery as the sales order contains freight amount at header level which helps calculate the excise duties as the prices quoted to customer include freight and duties.
So now is that possible to update the delivered quantity at contract level so that undelivered quantity can be referenced to create another sales order and can be delivered.
To describe the process:
A contract will be created, a sales order will be created for required delivery quantity then delivery will be created. In case due to some problems if delivery quantity is less than sales order then the undelivered quantity will be getting updated in sales order. and the sales order undelivered quantity will be rejected and the contract will get updated.
Please help.
Regards
Amit

Consignment and Reservations

Hi,
I need help with the following:
If you draw a reservation intended to consume cosigned material, but this material# has a balance as standard stock as well, when is the material identified as consigned in the reservation/GI process? In other words, how will the system know to subtract this material from a special stock balance? And what if it has more than one special stock balance, ie more than one vendor code? Are these balances created in the stock system when Info Records for consignment are created?
Thanks to anyone that can help.

hi,
Please help me on how to view consignment stock using tcode MB54, when i run this report the message is no stock exists for specified data.
here the process of consignment in our company
1. create reservation tcode MB21 with movement type Z11
2. Printing of Picklist then turned over to warehouse for pick and pack.
3. confirmation of reservation using tcode MB1B with movement type 311 click the reservation and encode the reservation #. then confirm and get the material doc.
4. Printing of stock transfer slip form with reference of material doc. base on good issue for consignment..then delivered the consignment outlet.
we have many consignment outlet here in our storage location.
in one storage location we have many outlet like sample
Storage location = ZS01 for Supervalue
Outlet                = Megamall
                         = Nort Edsa

Funds reservation with material reservation

Hello all,
The matter I need help with is funds reservation with material reservation, as the title says.
I have done some research about this and although [this thread|Material Reservation; and [this note|https://websmp230.sap-ag.de/sap(bD1lbiZjPTAwMQ==)/bc/bsp/spn/sapnotes/index2.htm?numm=91036] say it is not possible, [this SAP Library page|http://help.sap.com/saphelp_erp60_sp/helpdata/en/17/aea93769928b7fe10000009b38f8cf/content.htm] and [this enhancement package overview|http://www.id.uzh.ch/dl/sw/sap/upgrade/EHP3_Overview.pdf] (p. 194) state explicitly that it is possible. I am going to be optimistic and assume the latter are valid, what still lacks however is information about where this configuration is to be made and how.
How can I enable the creation of commitments upon material reservation?
Any help will be appreciated.
Thanks in advance.

Hi,
There is no automatic linkage/iteractions between the two, at least not up to release 6.02 (for more recent packages I'm not sure).
