Hi Itzíar Armentia Arroniz,
Thanks a lot for your suggestions. I have come across your post while searched this changing the Sender ID for dunning. It really meant a lot. Then I copied this function module and did the changes. Then where do we need to give this copied function module(Z_PRINT_DUNNING_NOTICE_SF) in configuration settings? Because my changes are not triggering. Did i miss anything? Could you pls help on this?. Thanks in advance!!!
