This error typically occurs when the record contains an invalid combination of Course Group State and Content Course Area Subcategory.  

Resolution:  If Course Content Area Subcategory is populated, then it must be a valid combination per the CrsGrpSt-ContentSubctgy combinations in the CALPADS Valid Code Combinations.

Reference (CrsGrpSt-ContentSubctgy, Valid Code Combinations)

Below is the Courses page, California Specific Fields tab.  The State Course Code (CRS.C3) and the Course Content Subcategory (CRS.CSC) fields must follow the valid code combinations.
