As we already know it is hard to debug VL10 transactions in general. Therefore SAP has introduced a user friendly way of jumping in to debug mode for VL10X transactions. It is done via a hardcoded breakpoint in the ABAP program. But can be activated via a user parameter. If you want to activate the debug mode for VL10 transaction, please add the user parameter “LEDSP_DEBUG_MODE” in transaction SU3.
