• What is the cause and solution for SAP error message RSB4HANA118 - BW CMOD exits are implemented and not supported in BW/4HANA ?

  The SAP error message RSB4HANA118 indicates that you are trying to use Customer Modifications (CMOD) exits in a BW/4HANA environment, which are not supported. This is a common issue when migrating from older versions of SAP BW to BW/4HANA, as BW/4HANA has a different architecture and does not support certain legacy features, including CMOD exits.
  Cause:
  The primary cause of this error is the use of customer enhancements (CMOD) that were available in previous versions of SAP BW but are not compatible with BW/4HANA. BW/4HANA has moved towards a more streamlined and simplified architecture, which does not include support for these types of enhancements.
  Solution:
  To resolve this error, you can consider the following approaches:
  
  
  Remove CMOD Exits: Identify the CMOD exits that are causing the issue and remove them from your BW/4HANA environment. This may involve refactoring your data flows or transformations to eliminate the dependency on these exits.
  
  
  Use Alternative Enhancements: Instead of CMOD exits, you can use other enhancement techniques that are supported in BW/4HANA, such as:
  
  ABAP Exits: Use ABAP code to implement enhancements in a way that is compatible with BW/4HANA.
  BAdIs (Business Add-Ins): These are the preferred method for implementing custom logic in BW/4HANA.
  HANA Calculation Views: If applicable, you can leverage HANA's capabilities to perform calculations and transformations directly in the database layer.
  
  
  
  Review Documentation: Consult the official SAP documentation for BW/4HANA to understand the supported enhancement techniques and best practices for migrating from older BW versions.
  
  
  Testing: After making changes, thoroughly test your data flows and reports to ensure that they function correctly without the CMOD exits.
  
  
  Related Information:
  
  SAP Notes: Check for any relevant SAP Notes that may provide additional guidance or updates regarding the transition from BW to BW/4HANA.
  SAP Community: Engage with the SAP Community forums to seek advice from other users who may have faced similar issues.
  Training and Resources: Consider SAP training courses or resources that focus on BW/4HANA to better understand the new architecture and capabilities.
  
  By following these steps, you should be able to address the RSB4HANA118 error and successfully adapt your BW environment to BW/4HANA.
