Parent-Student Relationship File Error Messages

Could not find Parent with ID 'XX' or Student with ID 'YY', as this parent/student was not imported 
 This error indicates that the  ParentID   or  StudentID   listed in the Parent-Student Relationship File does not match any record in the imported Parent File or Student File . 
 Example : 
 
 If the ParentID in the relationship file is  12345  but no parent with this ID exists in the Parent File, the system will flag this error. 
 Similarly, if the StudentID is  67890  and it doesn’t exist in the Student File, this error will appear. 
 
 How to Fix 
 
 Verify the Parent File  - open the Parent File and confirm the ParentID  XX  exists and was correctly imported. 
 Verify the Student File  - open the Student File and ensure the StudentID  YY  exists and was correctly imported. 
 Update the Relationship File  - correct any mismatched or missing ParentIDs or StudentIDs in the Parent-Student Relationship File. 
 Re-import the corrected files  - import the Parent File and Student File first, followed by the Parent-Student Relationship File.
