Our scenario is during MIGO GR we are creating batches with a custom number range based on the unit of entry on the PO. For example if we are procuring and receiving material A as Pallets with the unit of entry PAL then the batch number to be generated will be PAL0000123. If for the same material A we are receiving as Drums then the batch number is DR00000123. Each batch is required as all have a specific characteristic value that must be maintained.
The next step in our process is to transfer these materials from one storage location to another using batch determination based on FIFO from MB1B. The batch determination is only at the material level and not the Unit of Entry such as PAL or DR and so the system will transfer whatever material was received first irregardless of the unit of entry in MB1B.
What we're looking for is a user exit during the MB1B transaction prior to the batch determination that will only select batches according to the value in the Unit of Entry field in MB1B. This will allow us to apply the FIFO strategy to only PAL or DR batches separately based on the batch number assigned during GR.
