Hi Al,
We haven't any specific reports with IR, but in another situation, DataCare erroneously finds an error in AP if AP, JC, and PO are all checked together. The same database checks clean if AP is checked by itself. In fact, the database is OK in that circumstance.
My feeling is that those phase 2 'errors' are in fact false, and that your IR is OK. What other modules are you checking with the overnight check? Are there any outstanding batch files in IR that are waiting to be retrieved (IRxxBTCH.dat)?
If there were no details as to the errors, is there any indication on the DataCare verbose log which file the errors are in?
