Hello Ratnesh,
Is it a regular input field?
You can use Fiddler to trace the resulting submit in a regular web browser.
You can also set the ICM trace level to 3, so you can have a dump of the HTML code that is received by the backend (before the ICM handover the content to a work process, that will call the ITS code from the kernel). Thus, you can check whether the content is being received by the SAP system.
Kind regards,
Cris
