Hello Christopher
The beginning issue is, that my customer was suddenly faced with pop-ups. And nobody changed anything in the system. ( ?)
I didn't find out the reason yet of the changed behaviour.
My customer uses the SAP BI 7.0.
Actually I am working with another customer, where the pop-ups doesnt appear, if the paramater is "I_SYNCHRONOUS" = ABAP_FALSE. But it is Version SAP BW 7.3
I will test neyt week your input.
Best regards
Christian
