Please clarify exactly which product(s) you are using and which versions. I am going to guess and say that you are likely using BI Publisher. If so, you should post your question in that forum. This area is for Oracle Forms.
Answer : I solved the issue above using the following steps.
The publish part of the log file was missing. Once this was noted the OPP service log gave more details. There was a certain ref that was failing.
So went back to look at the RTF since this was the point of failure and it was identified.
There the item details were not visible without loading an XML. When I double clicked without loading the XML file I got an error "Compile error. Hidden module Module_EditFF...."
Upon Googling the answer was more clear : Oracle Applications: Compile error in Hidden module: Module_editFF in Oracle BI Publisher
My BI publisher had caused me troubles over the past few days and upon clean up and re-install it works like a charm.
Problem solved. Loaded my RTF using the new set-up. Double clicked on the field item and set the details I wanted using the "Add Help Text.." button and using both the tabs "Status bar" and the "Help Key(F1)".
Reloaded the Template, ran the concurrent program ==> Excel output obtained.
