IT31 is used to link sap numbers to each other in cases when an employee has been working for Organisation in two different countries, for example has worked in Norway (20xxxxxx) and then moves to Denmark (90xxxxxx). The purpose is to get history data in place from old pers no for the new pers no also.
Now it seems that when trying to use Create function in IT31 through PA30, it does not work - nothing is being saved.
Here's an example person who used to work in Norway but is now working in Denmark:
old sap no 20xxxxxx
new sap no 90xxxxxx
We are not able to link sap numbers
The reference link between the personnel numbers has not been created.
