• What is the cause and solution for SAP error message CACSCHECK115 - The namespaces in function modules &1 and &2 overlap ?

  The SAP error message CACSCHECK115 indicates that there is a conflict between the namespaces of two function modules. This typically occurs when two function modules are defined in such a way that they share the same namespace, which can lead to ambiguity and potential issues in execution.
  Cause:
  The error arises when:
  
  Two function modules are created in the same namespace (e.g., both in the same package or with the same naming convention).
  There is an overlap in the naming conventions or the way the function modules are structured, leading to confusion in the system about which function module to call.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Identify the Function Modules: Check the names of the function modules mentioned in the error message (represented as &1 and &2). You can do this by looking at the transaction code SE37 (Function Builder) or SE80 (Object Navigator).
  
  
  Review Namespace Usage: Ensure that the function modules are defined in different namespaces. If they are in the same package, consider moving one of them to a different package or renaming one of the function modules to avoid the overlap.
  
  
  Rename Function Modules: If the function modules are indeed conflicting, you may need to rename one of them. This can be done in the Function Builder (SE37) by using the "Rename" option.
  
  
  Check for Dependencies: If other objects (like programs, classes, or other function modules) depend on the conflicting function modules, you will need to update those references accordingly after renaming.
  
  
  Transport Requests: If you are working in a development environment, ensure that any changes you make are included in a transport request for proper migration to other environments (like QA or Production).
  
  
  Testing: After making the necessary changes, thoroughly test the affected functionality to ensure that everything works as expected and that there are no further conflicts.
  
  
  Related Information:
  
  Namespace Management: Familiarize yourself with SAP's namespace management practices to avoid similar issues in the future. SAP recommends using a clear and consistent naming convention for function modules and other objects.
  Documentation: Always document any changes made to function modules, especially if they are part of a larger project or system.
  SAP Notes: Check the SAP Support Portal for any relevant SAP Notes that might provide additional guidance or solutions related to this error.
  
  By following these steps, you should be able to resolve the CACSCHECK115 error and prevent it from occurring in the future.
