Error description
A data mapping and validation issue was identified in how system identifiers were handled for Db2 Data Sharing Groups. The identifier was incorrectly derived from the Data Sharing Group name instead of the individual member attach names, resulting in invalid values being used. In addition, this issue was not consistently detected because identifier validation was conditionally enforced based on the deployment mode. As a result, errors were allowed to pass in CI environments but were blocked in CD environments. Based on feedback from SMEs, the logic has been updated to ensure accuracy and consistency. The system identifier is now sourced from the correct member-level attach name for Data Sharing Groups, and validation is applied uniformly across all deployment types without conditional exceptions.
