• What is the cause and solution for SAP error message MDC_SANITY_MODEL_SET003 - There must be exactly one root table (currently &1) ?

  The SAP error message MDC_SANITY_MODEL_SET003 indicates that there is an issue with the data model configuration in the SAP system, specifically related to the root table in a multi-dimensional model (MDC). The error message states that there must be exactly one root table defined, but the system has detected that there is currently more than one root table (indicated by &1).
  Cause:
  
  Multiple Root Tables: The primary cause of this error is that the data model has been configured with more than one root table. In a multi-dimensional model, there should only be one root table that serves as the starting point for the data hierarchy.
  Incorrect Model Configuration: The model may have been incorrectly set up, leading to multiple tables being designated as root tables.
  Data Model Changes: Recent changes to the data model, such as adding or modifying tables, may have inadvertently created multiple root tables.
  
  Solution:
  To resolve this error, you need to ensure that there is exactly one root table in your data model. Here are the steps to do that:
  
  Review the Data Model: Open the data model in the SAP system and review the configuration of the tables. Identify all the tables that are currently set as root tables.
  Identify the Correct Root Table: Determine which table should be the single root table based on your data model's design and requirements.
  Remove Extra Root Tables: For any additional tables that are incorrectly set as root tables, change their configuration to remove the root designation. This may involve adjusting the relationships or hierarchies in the model.
  Validate the Model: After making the necessary changes, validate the data model to ensure that it meets the requirements and that there is now only one root table.
  Test the Model: Once the changes are made, test the data model to ensure that it functions correctly without any errors.
  
  Related Information:
  
  Documentation: Refer to the SAP documentation for multi-dimensional models and data modeling best practices to understand the requirements for root tables and data hierarchies.
  SAP Notes: Check for any relevant SAP Notes that may provide additional insights or solutions related to this error message.
  Support: If you are unable to resolve the issue, consider reaching out to SAP support or consulting with a technical expert who specializes in SAP data modeling.
