You can generate mail merge letters from Oracle HRMS using Web ADI.
Web ADI retrieves the data and downloads it directly into a template letter (which you can also store in the Oracle applications database) to form the mail merge.
When you create a document for a mail merge, ensure that you select Word as the viewer, and check the Reporting check box.
Your system administrator must set up integrators to enable the letter generation to take place.
In addition, the layout associated with the letter generation process must have the same name as the letter created in the Letter window in the Oracle HRMS application. This associates a letter with an assignment status in Oracle HRMS or an enrollment status in OLM, and links the letter to the layout.
