In SAP CRM, the SAP User ID has to be created as a business partner if the user id needs to be used as a partner in the transactions. For example, if there is an employee responsible field in a sales order/quotation, then the user id which is used to create the sales transaction should have an associated BP created in the system.
User Name (SAP User ID) can be created as a BP using the standard BP transaction, selecting the “Identification” tab, going to the “Employee Data” section. The trick is to select the BP role “Employee”.
Step 1 : Create the BP using tcode [ BP ]
Step 2 : Select the BP Role of “Employee” and go to “Identification” tab
Step 3 : Enter the user id for which the BP is being created.
