Batch determination along with WM pick strategy

[Former Member]

Hi,

     I came across this statement on SAP help.

"If batch determination has already been carried out in Sales & Distribution or in Production, you cannot run batch determination again in the Warehouse Management System. The system only searches for stock for batches determined in the sales order or delivery, and removes them from storage using WM stock removal strategies such as FIFO or LIFO."

I am trying to figure what this means. Maybe its a simple thing I cannot see.

I have 2 batches. Material has a FIFO search strategy in the mtl master

Batch X --> GR date 11/15/2013 and SLED 11/29/2013. Located in bin 01-01-01

Batch Y --> GR date 11/14/2013 and SLED 11/30/2013. Located in bin 01-01-02

When I run batch determination, which batch will the system pick. Will it be X (due to more SLED) or will it be batch Y due to FIFO strategy?  Is it that only when I have the same batch in multiple bins then the system will pick as per the FIFO after batch determination has chosen the batch expiring first ?

I am trying to find out how FIFO in WM works with batch determination via SLED.

Thanks

Hi,

"When I run batch determination, which batch will the system pick. Will it be X (due to more SLED) or will it be batch Y due to FIFO strategy?"

Well, depends on your batch determination strategy...

The batch determination first of all ist not about the SLED or FIFO, but about other characteristic you want to select your batch from, like purity, or something like that. One characteristic might also be that a certain miminum number of days for the SLED must still be.

Then from the batches possible for your criteria you can sort the batches, that is still part of the batch determination. Here you can sort according to SLED if it is part of the batch information. So FIFO usually does not play any role at that moment.

FIFO only comes into game if you have more then one bin with the same batch determined by the batch strategy. Then the piciking strategy will pick the quant with the oldest GR date. If all bins with the batch have the same GR date, it will take the quant with the lowest number. The warehouse will not consider any other batch.

Does help?
