Start condition for PPF Action (Start Condition Parameter)

Hello all,

I have created the Start Condition (BAdI EVAL_STARTCOND_PPF) for the PPF Action. It works rightly: the PPF Action is executed if the Start Condition is met.

But now the button 'Start Condition Parameter' appears in the business transaction (Tab: PPF Actions) for my PPF Action. I didn't define any Condition Parameter for the PPF Action in SPPFCADM.

By pressing on this button the business transaction terminates with runtime error (Runtime Error: OBJECTS_OBJREF_NOT_ASSIGNED_NO, Except.: CX_SY_REF_IS_INITIAL).

Do anyone have ideas how I can get out this button or how to make the button execution correct (maybe set any settings)?

Thanks in advance
