The SAP error message SV759, which states "You are not authorized to maintain this field value," typically indicates that the user does not have the necessary authorization to modify a specific field in the SAP system. This can occur in various contexts, such as when trying to change data in a transaction, maintain master data, or update configuration settings.
Cause: Authorization Issues: The user’s role or profile does not include the necessary authorizations for the specific field or transaction. Field Status Group: The field may be set to "Display" only in the field status group configuration, preventing any changes. Custom Authorization Objects: There may be custom authorization checks implemented in the system that restrict access to certain fields based on user roles. Transaction-Specific Restrictions: Certain transactions may have additional restrictions based on the user's organizational unit or other criteria.
Solution: Check User Authorizations: Use transaction code SU53 immediately after encountering the error to see which authorization check failed. Review
