How To Fix 5M051 - CPR no. is incorrect according to modulus check

SAP Error Message - Details

• Message type: E = Error

• Message class: 5M - Error Messages for Denmark

• Message number: 051

• Message text: CPR no. is incorrect according to modulus check

What causes this issue?

The specified CPR number is invalid. The modulus check routine for the
CPR number fails.
This can happen if, for example, you try to enter a temporary CPR
number for an employee who has recently immigrated.

System Response

The system rejects further processing until a suitable entry has been
made.

How to fix this error?

Enter a valid CPR number. Under certain circumstances, the employee is
unable to submit a CPR number that the check routines will accept (as
in the above example).
In this case, you can use special CPR numbers which, like the official
numbers, start with a 6-digit date of birth, and end with the following
4 digits: 0000, 9991, or 9992. If you need a temporary CPR number for
male employees, enter 9991. If you need a temporary CPR number for
female employees, enter 9992. These are also accepted during payroll
runs. 0000 is mainly used for reasons of compatibility.
