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

Hi there,

My current environment is 4.2 sp3 - since two weeks , few of the reports built out of a unv universe are throwing the error “An internal error occured while calling 'processDPCommandsEx' API. (Error: ERR_WIS_30270)“

The error is across all users, I have tried refreshing the report on rich client, applet and html interfaces. Republished the universe, revoked access and granted access to the universe but nothing worked.

However, If I remove ANY object in the data provider and add it back the report refreshes just fine.

This has affected only few of the reports for that particular universe.

Could you please help me resolve this?
