The mandatory variable " " has not been given a value. (WIS 00000)

We just upgraded our BO system to SP6P5 because we had to wait on the tracelog desktop fix which originated in SP6P4. I have come across a new error which relates to BEx prompts via WEBI consumption.

I have a report based off of one BICS, Within the BEx, I have InfoObjects restricted by variables via customer exit and manual input/default value. The objects are in the Character Restrictions section of the BEx. The only variable which is based off of a customer exit is giving me an error when I try to execute it in SP6P5. I receive the following errors below:

I noticed when I turned off auto-refresh from the WEBI document properties then I received a new error: "The mandatory variable " " has not been given a value. (WIS 00000)".

Anyone have any ideas?

Thanks!
