  The SAP error message PSB_API_MSGCL125 typically occurs in the context of project management and scheduling within the SAP system, particularly when using the Project System (PS) module. This error indicates that backward scheduling cannot be performed because a finish date has not been entered.
  Cause:
  The error arises when:
