• What is the cause and solution for SAP error message RSRV102 - Master data table &1 exists in the database ?

  The SAP error message RSRV102 indicates that a master data table already exists in the database. This typically occurs during the process of data modeling or when trying to activate a data source or InfoObject in SAP BW (Business Warehouse). The error suggests that there is a conflict because the system is attempting to create a table that already exists.
  Cause:
  
  Existing Table: The master data table for the InfoObject you are trying to activate already exists in the database.
  Incomplete Deletion: Previous attempts to delete or deactivate the InfoObject may not have been completed successfully, leaving remnants in the database.
  Transport Issues: If you are transporting objects from one system to another, there may be inconsistencies between the source and target systems.
  
  Solution:
  
  
  Check Existing Tables: Use transaction code SE11 (Data Dictionary) to check if the master data table exists. If it does, you may need to decide whether to delete it or modify your activation process.
  
  
  Delete the Table: If the table is not needed, you can delete it using transaction code SE14 (Database Utility). Be cautious with this step, as it may lead to data loss if the table contains important information.
  
  
  Re-activate the InfoObject: After ensuring that the table is either deleted or confirmed to be correct, try reactivating the InfoObject or data source again.
  
  
  Check for Inconsistencies: Use transaction RSRV (Data Warehousing Workbench) to check for inconsistencies in the InfoObject or data source. This transaction can help identify issues that may be causing the error.
  
  
  Transport Consistency: If the issue is related to transport, ensure that all relevant objects are correctly transported and activated in the target system.
  
  
  Consult SAP Notes: Check the SAP Support Portal for any relevant SAP Notes that may address this specific error or provide additional guidance.
