Diagnosis
The HR_FR_GET_CONTRACT function module deflects the employee's contracttype. This module searches for this information in infotype "Contract elements" (0016) or "Assignment" (0001) depending onthe settings of the CONTR constant given in table 511K.
The system has not been able to use these settings to identify thecontract type in either of these infotypes.

Procedure
Check the coherency of the information entered in table T511K for theCONTR constant.
