Smart SAP Assistant

• What is the cause and solution for SAP error message RSO_RES_QMSGS143 - Target object is already used in other mapping definition. &1 ?

  The SAP error message RSO_RES_QMSGS143 indicates that a target object (such as a data target or InfoObject) is already being used in another mapping definition within the SAP BW (Business Warehouse) environment. This typically occurs when you attempt to create or modify a transformation or data flow that references a target object that is already in use elsewhere.
  Cause:
  
  Concurrent Usage: The target object is already assigned to another transformation or data flow, which prevents it from being reused in the current context.
  Incorrect Mapping: There may be an attempt to map the same target object in multiple transformations, which is not allowed.
  Object Locking: The target object might be locked due to ongoing processes or transactions.
  
  Solution:
  
  
  Check Existing Mappings: Review the existing transformations and data flows to identify where the target object is currently being used. You can do this by:
  
  Navigating to the relevant InfoProvider or transformation in the SAP BW modeling tools.
  Checking the mappings and transformations associated with the target object.
  
  
  
  Modify or Remove Conflicting Mappings: If you find that the target object is being used in another mapping that is not needed, consider modifying or removing that mapping to free up the target object.
  
  
  Use a Different Target Object: If the target object must remain in use in its current mapping, consider using a different target object for your new mapping definition.
  
  
  Check for Locks: Ensure that there are no locks on the target object. You can check for locks in the SAP system using transaction codes like SM12 (to view and manage locks).
  
  
  Consult Documentation: Refer to SAP documentation or help resources for more detailed guidance on managing transformations and mappings in BW.
  
  
  Related Information:
  
  SAP BW Modeling: Understanding how transformations and data flows work in SAP BW is crucial. Familiarize yourself with the concepts of InfoProviders, transformations, and data targets.

  RSA1: Data Warehousing Workbench
  RSO1: Create Transformation
  RSO2: Change Transformation
  
  
  SAP Notes: Check for any relevant SAP Notes that might address specific issues related to this error message or provide updates and patches.
