SAP consultants and developers often have to meet custom business requirements for which there is no standard SAP functionality. In the search for a suitable user exit, they may find one that is close, but lacks one or more essential parameters. This article shows you a simple method for accessing data fields in the main program other than those formally provided as parameters to a user exit function module. By using field symbols and a few lines of code shown in the article, you can access fields, structures, and internal tables from within a user exit function module. Find out how field symbols can help you navigate around the problem of missing parameters and get extra mileage from user exits.
