Availability check for the inbound process

[Former Member]

Hello Experts,

We have implemented Decentralized warehouse management in spare parts

warehouse.As a part of the process, we need to transfer the material

stock within the warehouse from Non-DWM S. Loc-N002 to DWM S. Loc-N001 in T-code MB1B with

mov.type-311.below are the steps being followed and issue details.

1) Initially there is stock of 10 qtys in Non DWM S.loc-N002

2) Go to T-code-MB1B. Put the input, movement type-311, plant-XXXX,

S.Loc-0002, Receiving S.loc-0001 and material with qty=10.

3) Press enter and save the document, system will create one inbound

delivery for qty=10.This delivery will get distributed to DWM

automatically.

4) Before confirmation of the transfer order of the first inbound

delivery,user can repeat the step 2 & 3 n number of times for

quantities 10 or less than 10 as there is no check for the material

available in 0002.

5) This has created the stock mismatch in central SAP and DWM system.

Is availability check possible for such inbound movement within the warehouse. If yes, please provide the steps to follow.

Here while executing MB1B only , system should check if the inbound deliveries are already created for the unrestricted stock material.

Hi,

I know and understand your error (frustration?). We've got the same scenario and it doesn't matter how good the training or workshops were, the people just post the transaction more than once.

So here's my idea:

1. make use of std reservations

2. use the user exit on delivery create and create a reservation (with delivery number referenced in the reservation) for the stock in the background when the delivery is created.

3. so when the next delivery is created, check against available stock (unrestricted less reserved) to determine if you can create a new delivery

4. once the delivery in the dwm system is completed and the idoc is send back to erp, the reservation created in step 2 must be cleared

It would definitely add value to a DWM scenario.

Hi,

We have two 2 alternative solutions for this issue.

1) we can use stock transfer betwwen two Slocs with Mov.types-313 and 315

2) & using user exit.

can't we not achieve this using availability check as we do in case of outbound deliveries.

Sandeep.

Hi,

Using mvnt 313/315 will not solve this....just tested it. I could have transfer more stock from my sloc in 2 seperate deliveries.

I tried the avail check as well, but nou luck. Will check some more and let you know.

Hi Sandeep,

Sorry...My mistake...313 could work, but it still leaves the door open for 311 mvnts.

Hi Sandeep

You want availability check for picking..

Is negative stocks allowed for your plant??

All the problem you have is from Issuing Storage Location end..dont allow negative stocks this should solve your problem of issuing the same stock..even when you have booked allready the stock..

Please let me know if my understanding is wrong..

Cheers
