An internal error while calling the 'process variable' API. I'm getting this error while creating a variable in Webi

Hi Guys,

We have recently upgraded our service pack for BOBJ XI 3.1 SP3 to SP6. After the upgrade some variables are missing and we are getting =????? in the place of variable.

I facing two issues with variables in Webi.

1. While trying to create a variable in webi and saving it i'm getting "An Internal Error while calling the "processVariable" API" error.

2. Even after some how creating the Variable and saving the webi, when we reopen the webi the variable is gone and it is displaying #SYNTAX in place of variable.

Please advise on resolving this issue.

Regards,

Anil
