Hello,
The reason that this error is coming out is that the system is looking for the work schedule in 01.01.1990 and it's not finding it.
The system searches for the valid work schedule using four main things:
- Personnel Subarea Grouping, you can check this by going to TCode SM30 and check view V_001P_N
- Employee Subgroup Grouping, you can check this by going to TCode SM30 and check view V_503_D
- Public holiday calendar, you can this by going to Tcode SM30 and check view V_001P_M
- The start and end dates of the work schedule rules in view V_T508A should be within the start and end dates when creating a record of IT0007.
check this configuration and your issue should be solved.
Hope that helps,
For more information please contact.
Thanks and regards,
Sally
