By default, SAP does not display the infotype name. But you can change it very easily.

Go to menu System => User Profile => Own data

The select last tab called "Parameters".

Then add User Parameter = HR_DISP_INFTY_NUM to the user profile with the parameter value set = X HR (note space between X and HR)

Now if you use transaction code PA20 or PA30, you can see the infotype number next to infotype name.

Hot keys are used for fast access to SAP functions.

• You can use T-code PPOME to delimit the position.
• There is also SAP delivered program for this purpose. T-code = RE_RHGRENZ4, program = RHGRENZ4

Program to delimit an object

T-code = S_AHR_61016380

Report = RPUAUD00
