WM/IM Stock mismatch

[kathryn_hoyne2]

Hi,

I've got a problem as we have a stock mismatch between WM & IM as a result of an issue with stock write on for Go Live.

When the stock was written into the live box via a 561 mvt, the WM functionality didn't run.

Config had to be tweaked to activate the WM piece.

We then cancelled the 561, but this created a negative entry in the storage type 998 - Aufnahme.

When the stock was re-entered on IM, the WM side didn't match due to this entry.

Have tried every trick I know to correct the WM stock.

Does anyone know how to correct/amend WM bin stock without adjusting IM stock???

Thanks,

Kathryn

HI,

Can u explain one material stock status in IM & WM.Whether quantity negative in WM is double the qty in IM.

I have 0 stock of 1 component in WM but a qty in IM.

The 562 generated a negative qty in the stock status 998.

When the stock was 561'd again, the total stock in WM is 0.

If I view the stock in Storage Type 002 - Shelf Storage, I can see it's correct.

But it still appears as 0 on LX23.

I think the only thing I can do is run LX23 to bring the IM & WM stocks in line, and then re-enter the stock.

Thanks,

Kathryn

you loaded the stock in MM as the warehouse was not assigned to the location in table T320, hence only MM was updated with quantity, WM not.

Then you assigned the warhouse to the location.

then you cancelled your initial stock load, which in turn removed quantity from MM AND from WM as WM was active at this point of time.

Result was 0 stock in MM and negative stock in 998 WM

Then you load stock again, so stock in MM became positive while in WM it became just zero.

This was a wrong cycle, you should not have activated the WM link before cancelling the initial stock.

You should have done this activation after cancellation of initial load, and before doing the new load.

To correct the situation you have to cancel your load again and redo you load.

this time, start with removing the assignmen.

then cancel you material documents.

this will result in zero stock in MM and zero stock in WM.

Then switch on the assignement.

then load your stock again.

Here you can read alternative options for datam migration with WM.

Will all WM records be wiped if I switch off the WM assignment in config??

The stock will go to 0 in the Warehouse yes?

nothing will happen to exsting warehouse stock if you remove the assignment.

without this assignment, MM movements will not interface to WM.
