What is your application release?
Is the issue with opening a form or with opening a report? From the title, you mentioned it's a form while in your post you are referring to an RDF file.
How To Determine Table and Column Name from a Field in a Form in 11i (Doc ID 259722.1) -- Applicable to R12 as well.
My Application Release is R12 and I am using the 10g builder.
The Issue is with the report and mentioned it to be Form in the heading by mistake.
Thanks for your time,
Thanks and regards,
Why can't you open the report using Reports Builder? I'm still not sure what layout you are looking for.
I think you should open the RDF with the report builder, in the report builder layout, it is easy to find out the formula column used to get the value of a column in the report.
