Employee group key & contradicts SI attribute &

What causes this issue?

A contradiction between infotypes 0013 (Social Insurance) and 0020
(DEUEV) was detected in period &V3&.
Person group key &V1& is not allowed in combination with SI attribute
&V2& from infotype 0013.
Example:
Person group key 118 (irregular employees) must have the appropriate
value for the SI primary attribute, 06 (irregular employees).
If secondary attribute 24 (low-income employees) is set in infotype
0013, then the person group key must be 102 (trainees) or 105 (student
employees).

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

How to fix this error?

Use a permissible value for the person group key or correct the
corresponding SI attribute in infotype 0013.
