  The SAP error message GMMASTERDATA127, which indicates that "IDC rate periods overlap," typically occurs in the context of the Grants Management (GM) module when there are overlapping periods defined for Indirect Cost (IDC) rates. This can happen when you try to create or modify IDC rate records that have conflicting date ranges.
  Cause:
  The error is caused by the following scenarios:

  Incorrect Data Entry: During the creation or modification of IDC rates, incorrect date entries may lead to overlaps.

  Solution:
  To resolve the GMMASTERDATA127 error, you can take the following steps:

  Delete or Archive Conflicting Rates:
  
  If certain IDC rates are no longer needed, consider deleting or archiving them to eliminate the overlap.
  
  
  
  Consult Documentation:
  
  Review SAP documentation or guidelines related to Grants Management and IDC rates for best practices in managing rate periods.
  
  
  
  Testing:
