An internal error occured while calling 'processDPCommandsEx' API (Error: ERR_WIS_30270)

Hi All,

We are facing issue  "An internal error occured while calling 'processDPCommandsEx' API (Error: ERR_WIS_30270)" while modifying a data provider of a report. We add a object to Select Clause, but while saving the data provider it gives this error.

We have also noticed few things -

1) This issue doesn't come on Web-I Rich Client or Java Report Panel. It only comes in Interactive Mode.

2) Even the Administrator user faces this issue, perhaps this error has nothing to do with Access, etc.

Technical Details -

1) BO4.0 SP7 Patch 7

2) DB: SAP BW / Connected through unv Universe.

3) OS Windows 2008 R2

The tracing showed below error in Web-I Processing Server logs -

**ERROR:C3_Calculator:CreateCalculator::unknown exception [kc3cdbCalc.cpp;2554]
