Inconsistent answers. BW system XXX returns ERROR BRAIN (629): Please enter a value for variable XXX
MSGV1: XXX

And also when i run webI report with 3 BW prompt (2 mandatory Prompt and 1 optional prompt) and 2 WebI  prompt it gives me Error in hyperlink.

Note : BEx filters are global variables so we cannot have the default values set for these filters

Please Refer the attached screenshot.

Can anyone help me.
