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.

1. If we see in PA30, the standard screen for 0023 (Other/Previous Employers) is:

2. Let us hide the field “Work Contract” & “Job” from the standard Infotype screen.

Go to SM30 & enter view name as “V_T588M”. Click on “Maintain”.

3. Enter the module pool program & click Ok. In our case it is MP002300.

4. Now click on ‘New Entries’ button.

5. Now enter the “Module Pool” (mandatory) “Standard screen” (mandatory).Press “Enter”.

6. After we press “Enter”, all the screen fields of the Infotype are shown along with their attributes.

7. Now, we can change the attributes according to our requirements by selecting the desired radio button. After that press Save.

8. Then Go to PA30 and check the changes done to the standard Infotype (here Infotype 0023). The fields we chose to hide gets hidden.
