• What is the cause and solution for SAP error message MDC_GW003 - Match group contains only two records, must be rejected on group level ?

  The SAP error message MDC_GW003, which states "Match group contains only two records, must be rejected on group level," typically occurs in the context of data matching processes, particularly in the SAP Master Data Governance (MDG) module. This error indicates that the system has identified a match group containing only two records, which does not meet the criteria for further processing or approval.
  Cause:
  
  Insufficient Records: The error arises because the matching logic requires a minimum number of records in a match group to perform a valid comparison or decision-making process. When only two records are present, the system cannot determine a clear match or conflict.
  Configuration Settings: The matching rules or thresholds may be configured in such a way that they do not allow for groups with only two records to be processed.
  Data Quality Issues: There may be issues with the data quality or completeness, leading to only two records being identified as a match group.
  
  Solution:
  
  Review Match Group Criteria: Check the configuration settings for the match group criteria in the MDG system. Ensure that the settings allow for processing of groups with more than two records.
  Data Quality Improvement: Investigate the records involved in the match group. Ensure that the data is complete and accurate, which may help in generating larger match groups.
  Adjust Matching Logic: If applicable, consider adjusting the matching logic or thresholds to allow for processing of smaller match groups, if that aligns with your business requirements.
  Manual Intervention: If the records are critical, consider manually reviewing the two records to determine if they can be processed individually or if further action is needed.
  
  Related Information:
  
  MDG Configuration: Familiarize yourself with the configuration settings in the MDG application, particularly those related to data matching and validation.
  Data Governance Best Practices: Implement best practices for data governance to ensure high-quality master data, which can help reduce the occurrence of such errors.
