Hi Brad,
many thanks for your quick reply.
I am not sure whether my code base is using that interface method. I could not find it.
My Gateway system is based on:
SAP_BASIS 702 0009
and all GW add-ons are on SP-Level 0006
I assume that I am not allowed to follow your approach.
My solution just depends on Gateway and not on SUP.
Regards,
Andreas
