DG filling with an identifier
I try to fill the field Special Provision (DTMD - SPPRO) with an identifier maintained at LS_UN_SUB level (NAM SYM identifier)
But I don't know if I can do this at customizing level or if I need to modify the DG Filling program.
In fact, I want to use the same process that currently exist for the filling of the UN number field (DGTMD - DGNU) in order to fill the field SPPRO.
Did somebody already done this? Can you help me to understand how I can do the assignment between a field in the DG Master and an identifier at LS_UN_SUB level?
Thanks in advance for your help
