• What is the cause and solution for SAP error message GMMASTERDATA220 - Relationship &1 &2 violates &3 cardinality of Relationship Type &1 ?

  The SAP error message GMMASTERDATA220 indicates that there is a violation of the cardinality rules for a specific relationship type in the context of the SAP General Ledger (GL) or the SAP Governance, Risk, and Compliance (GRC) module. This error typically arises when you are trying to create or modify a relationship between master data objects (such as funds centers, cost centers, or other organizational units) that does not comply with the defined cardinality constraints.
  Cause:
  The cardinality of a relationship type defines how many instances of one object can be associated with instances of another object. For example, a relationship might be defined such that:
  
  One funds center can be associated with multiple cost centers (1:N).
  A cost center can only be associated with one funds center (1:1).
  
  The error message GMMASTERDATA220 indicates that the relationship you are trying to establish violates these predefined rules. This could happen due to:
  
  Attempting to create a relationship that exceeds the allowed number of associations.
  Incorrectly configured relationship types in the system.
  Data inconsistencies or duplicates in the master data.
  
  Solution:
  To resolve the GMMASTERDATA220 error, you can take the following steps:
  
  
  Review the Relationship Type Configuration:
  
  Check the configuration of the relationship type in the SAP system. Ensure that the cardinality settings are correctly defined according to your business requirements.
  
  
  
  Validate Master Data:
  
  Review the master data objects involved in the relationship. Ensure that there are no duplicates or inconsistencies that could be causing the violation.
  
  
  
  Adjust the Relationship:
  
  If you are trying to create a new relationship, ensure that it adheres to the cardinality rules. You may need to modify or delete existing relationships to comply with the constraints.
  
  
  
  Consult Documentation:
  
  Refer to SAP documentation or help resources for specific details on the relationship types and their cardinality settings. This can provide insights into how to properly configure and manage relationships.
  
  
  
  Testing:
  
  After making adjustments, test the changes in a development or test environment before applying them to the production system to ensure that the error is resolved.
