Yes, it's possible though some developers "delete" the record by changing a value in a field so that the record is no longer related to the parent record and thus disappears. That way you can find the record and undo your delete if that action was performed by mistake.
To Delete the record:
Since ths is 5.5, use Go To Related record to find the related record in the related file.
Write a script in the related file that deletes the record.
In your first file have your script use GTRR to isolate the record followed by a perform script step that performs the delete script in the related file.
You never cease to amaze me...thanks again for your advice and help! It works perfectly.
PS - On the note of "hiding" files...I think I may use that technique in other situations, but in this case it is just fine to "lose" the record. We have a more complete record of the update elsewhere. Thanks for the tip!
