I have added standard Batch class characteristic LOBM_UDCODE that is provided by SAP for Usage decision code.
I am creating inspection lot against Material and Batch no. I see that UD code is correctly updating in my Batch class whenever I take a UD from QA32.
At times, I have to reset UD code from QA12 Tcode. Whenever I do this, I see that SAP is raising an error message as shown below,
Question: Has anyone added this standard characteristic to Batch class and tried to reverse UD? Is there a reason SAP will not write an empty UD code to Batch class whenever UD has been reset?
