Locating BAPI Functions
You can explore the list of BAPI's in the SAP system targeted by that Destination through the Service Object Designer Object Explorer.
In the Rfc/Bapi Explorer section, you can define filters to limit the list of BAPIs returned. This is a good idea if you work with a particular set of BAPIs often or if you have a large set of BAPIs. When declaring a filter, use a * character as a wildcard, like the example below where we return all the "EMPLOYEE" BAPIs.
