• What is the cause and solution for SAP error message RSCRM179 - Callback module not found ?

  The SAP error message RSCRM179: Callback module not found typically occurs in the context of SAP BW (Business Warehouse) or SAP BI (Business Intelligence) when there is an issue with the data extraction process, particularly when using the SAP CRM (Customer Relationship Management) system as a source.
  Cause:
  The error usually indicates that the system is unable to find the specified callback function or module that is required for the data extraction process. This can happen due to several reasons:
  
  Missing or Incorrect Function Module: The function module that is supposed to handle the callback is either missing or incorrectly defined in the system.
  Transport Issues: If the function module was recently transported from another system, it may not have been transported correctly or completely.
  Configuration Issues: There may be configuration issues in the data source or in the extraction settings that prevent the callback from being recognized.
  Authorization Issues: The user executing the extraction may not have the necessary authorizations to access the callback function.
  
  Solution:
  To resolve the RSCRM179 error, you can follow these steps:
  
  
  Check Function Module:
  
  Go to transaction SE37 (Function Builder) and check if the required function module exists.
  If it does not exist, you may need to create it or transport it from another system.
  
  
  
  Review Data Source Configuration:
  
  Check the configuration of the data source in transaction RSA1 (Data Warehousing Workbench).
  Ensure that the data source is correctly set up and that the callback function is properly assigned.
  
  
  
  Transport Check:
  
  If the function module was recently transported, verify that the transport request was completed successfully and that all necessary objects were included.
  
  
  
  Authorization Check:
  
  Ensure that the user has the necessary authorizations to execute the function module. You can check this in transaction SU53 (Authorization Check) after the error occurs.
  
  
  
  Debugging:
  
  If the issue persists, you may need to debug the extraction process to identify where the callback is failing. Use transaction SE80 or SE37 to analyze the code.
  
  
  
  Consult SAP Notes:
  
  Check the SAP Support Portal for any relevant SAP Notes that may address this specific error. There may be patches or updates available that resolve the issue.
