1. I have create Characteristics with assign table MCH1 and field HSDAT. I want to batch determination with FIFO based batch production date. Then I have create a class and assign that characteristics. 2. Create a sort rule with ascending order. 3. Create selection criteria in MBC1. 4. Tick on OMCG with 261 movement type. But when I am going to confirmation in COR6 then during batch determination the first batch that is showing in MMBE (Alphabetically) that is picking. WHY???
