The linking between Personnel No and the SAP Userid is pretty useful when we are required to map both of these ( as in case of SAP Employee Self Service). The mapping is available in the infotype 0105. This information can be maintained as shown below:
1. Go to transaction PA30. Enter the infotype 0105 in the “Direct selection” and 0001 in the subtype. Click on Create.
2. Following screen appears:
Enter the start date and the end date as required. Also enter the SAP User-id to which this personnel number has to be mapped.
Click on Save to update your records.
