eGrace AIM invoice form is failing with FRM-92101

I had a form named AIM invoice form; it shows all AIM invoices. In the form there are five different sub forms called “Header, Items, Texes, Terms, and Messages”.

When ever I search a specific invoice it will shows the header details of invoice. Then when I press the ‘next tab’ it will show invoice details in all sub forms like:  Items, texes, Terms …

 

But I had an issue when I query invoice and directly to go Items form without press ‘next tab’ getting the following error:

“FRM-92101: There was a failure in the forms server during start up. This could happen due to invalid configuration. Please look into the web-server log file for details.”
