• What is the cause and solution for SAP error message MDG_HDB_SEARCH014 - Multiple active data models exist for the object type code ?

  The SAP error message MDG_HDB_SEARCH014 indicates that there are multiple active data models for a specific object type code in the Master Data Governance (MDG) system. This situation can lead to confusion in data processing and retrieval, as the system does not know which data model to use.
  Cause:
  The error typically arises due to one of the following reasons:
  
  Multiple Active Data Models: There are multiple data models defined for the same object type, and they are all marked as active. This can happen during configuration changes or when new data models are created without deactivating the old ones.
  Configuration Issues: Incorrect configuration or setup in the MDG system can lead to multiple active data models being unintentionally created.
  Transport Issues: If data models are transported from one system to another (e.g., from development to production), it may lead to inconsistencies if not managed properly.
  
  Solution:
  To resolve the error, you can follow these steps:
  
  
  Identify Active Data Models:
  
  Go to the MDG configuration transaction (usually MDGIMG or SPRO).
  Navigate to the relevant section for data model configuration.
  Check the list of active data models for the specific object type code that is causing the error.
  
  
  
  Deactivate Unnecessary Data Models:
  
  Determine which data models are necessary and which can be deactivated.
  Deactivate the redundant or outdated data models to ensure that only one active data model exists for the object type.
  
  
  
  Review Configuration:
  
  Ensure that the configuration for the data models is correct and that there are no unintended duplications.
  If necessary, consult with your SAP Basis or MDG team to ensure that the configuration aligns with best practices.
  
  
  
  Testing:
  
  After making changes, test the system to ensure that the error no longer occurs and that the correct data model is being used.
  
  
  
  Documentation:
  
  Document the changes made to the data models for future reference and to prevent similar issues from occurring.
  
  
  
  Related Information:
