Update Marketing Attributes via FB CRM_MKTBP_ASSIGN_ATTRIBUT_TAB

Hello SDN Members,

I have written a BSP where I try to update Marketing Attributes via the function module CRM_MKTBP_ASSIGN_ATTRIBUT_TAB. Unfortunately the update via the BSP does not save the data. When I call the function module in Transaction SE37 it works perfect. Any suggestions?

Regards

Gregor
