Here for our client we have implemented SAP 5 years back. At that time for Batch issue FIFO is followed. For that at that time just in SU01 for user ids using parameter FIFO they have made system to follow FIFO.
So during MB1A user will just enter the material code, qty and just enters * in the place of batch. System sorts the batch with respect to batch creation date and issues the batch
Now the issue is where there are 2 batches which is been created on the same date....First time system issues batch A and the second time while trying to issue system is picking the batch B.before Batch A qty becomes 0.
Now my question is
!. How to rectify it? Do i need to create characteristics? Please let me know the procedure?
2. I have n number of batches as of now in system.
