  The SAP error message /SAPAPO/CURTO085 typically occurs in the context of Advanced Planning and Optimization (APO) when there is an issue with the relationships defined between operations in a production or planning process. The message indicates that the system has detected an invalid relationship between operations, specifically that only an "End-Start" relationship is valid for the specified operation.

  Review the relationships between the operations. Ensure that they are set correctly, and that only End-Start relationships are used where required.

  Check the definitions of the operations involved. Ensure that they are correctly defined and that all necessary parameters are set.
