Diagnosis
The structure of the Reference Personnel Number Infotype (0031) hasbeen enhanced.

System Response
In this release, the reference personnel number data is removed frominfotype 0031. In the future, the references will be stored as a linkto a new person object (CP). Infotype 0031 is deleted.
Since we assume from your DDIC information that you have enhanced theinfotype with your own fields, the employees were not converted.

Procedure
You must put your additional data in another infotype.
Create the additional fields in another infotype. It may be better tocreate the additional fields in their own infotype.
Then copy the relevant data from infotype 0031 to the relevant newinfotype (conversion report).
Then start conversion for the employee manually (ProgramRPU46CX_CENTRAL_PERSON_ONLINE)
