• What is the cause and solution for SAP error message RTCMMD102 - Flag at least one hierarchy level as a category ?

  The SAP error message RTCMMD102, which states "Flag at least one hierarchy level as a category," typically occurs in the context of SAP Master Data Governance (MDG) or when working with hierarchical data structures in SAP. This error indicates that the system requires at least one level of the hierarchy to be designated as a category for proper data processing.
  Cause:
  The error is triggered when you are trying to create or modify a hierarchy structure, but none of the hierarchy levels have been marked as a category. In SAP, categories are essential for defining the nature of the data at different levels of the hierarchy, and without at least one level flagged as a category, the system cannot proceed with the operation.
  Solution:
  To resolve the RTCMMD102 error, follow these steps:
  
  
  Access the Hierarchy Structure: Navigate to the hierarchy structure you are working with in SAP.
  
  
  Edit Hierarchy Levels: Go to the specific hierarchy levels that you have defined.
  
  
  Flag a Level as a Category:
  
  Identify at least one level in the hierarchy that should be treated as a category.
  In the properties or settings for that level, look for an option to flag it as a category (this may be a checkbox or a dropdown selection).
  Ensure that this level is marked appropriately.
  
  
  
  Save Changes: After making the necessary changes, save the hierarchy structure.
  
  
  Re-attempt the Operation: Once you have flagged at least one level as a category, try to perform the operation that previously resulted in the error.
