I have number of forms having many free tables in their dataenviroments.

If error occurs on form dataenvironment opening, VFP 5 displays general error message, for example

Error loading file - record number 27. DOCLIST .Loading form or the data environment : File access is denied
This message is written to users logfiles.

How I can determine which table causes this error ?

Record 27 is a form dataenvironment record, not a cursor record.
I tried aerror(), dataenvironment error event, message(), sys(2018)
but none of them will not give an error.

At runtime, I want to know exactly which table causes this error in users computer. So it seems that it is not possible to use VFP dataenvironments at all.
Removing all dataenvironments from all of my forms and creating them manually is a lot of work.
