Install OATS in your machine. Open Openscript. You can find record button in OpenScirpt. When you start recording a browser will popup. Do navigations on that browser.
For recording forms select Oracle EBS/Forms for creating new script
OATS is installed.
When I recording oracle web forms in brouser I don't have any problems.
But when opens "Applications", OpenScript does not react to my actions.
Before start recording the script, make sure to use "Oracle EBS/Forms" as an accelerator. Without this, OpenScript will not able to record Forms.
