Incorrect call: different usage of update

What causes this issue?

The system updates entries in database table DFKKMD_ALTROLE. The data
can be updated directly as well as by using the SAP update program. Both
types are used within a logical unit of work (LUW). Therefore the data
inconsistency cannot be allowed.

System Response

The program terminates.

How to fix this error?

Check the posting program. Within an LUW, the data is only allowed to be
updated either directly only, or only by the SAP update program.
