Problem with update rules

Hi,

I encountered a problem with Update Rules.

The infosource 8PPROCWPH is connected to two cupes PPROCWP1 and PPROCWP2. The implemented ABAP logic in both Update Rules are working fine, when i try to upload one data target at a time

The problems occurrs, when I try to update both data target at once,update rules are not been used.

Reagrds,

Anita
