Many thanks for this Yawa...I think you pointed me to the right path. Just two more things, if you don't mind.
1.) Which BTE to use?
I can see BTE 1060 (Dunning check MHND) and BTE 1061 (Delete indicator MHND). In BTE1060, I can see that there's a check on the field MHND-XZALB. But I would need BTE1061 to actually change the value? Can I actually go directly to BTE1061 instead of checking it first?
2.) If I use the BTE, how would the dunning program pick up the BTE?
BR,
Tess
