Hello, experts! I'm new to enhancement in ABAP.
My purpose is to calculate the value of EAN/UPC field automatically when a new alternate UOM (AUn) added to the list by selecting one UOM group from the drop-down box 'Units of measure grp'. Please refer to the picture below.
But I have no idea where to add my code. Could you tell me what the BADI or User Exit is? I will be appreciate it!
