• What is the cause and solution for SAP error message E0635 - Basic IDoc type & and extension & have not yet been combined ?

  The SAP error message E0635 indicates that there is an issue with the IDoc (Intermediate Document) configuration, specifically that the basic IDoc type and its associated extension have not been properly combined. This error typically arises when you are trying to process an IDoc that requires a specific extension but the system cannot find the necessary combination of the basic type and the extension.
  Cause:
  
  Missing Extension: The extension for the specified basic IDoc type has not been created or activated in the system.
  Incorrect Configuration: The basic IDoc type and extension may not be correctly linked in the IDoc configuration settings.
  Transport Issues: If the IDoc type and extension were transported from another system, there may have been issues during the transport process that caused the extension to not be available.
  Development Environment: If you are working in a development environment, the extension may not have been created yet.
  
  Solution:
  
  Check IDoc Types: Verify that the basic IDoc type and its extension exist in the system. You can do this by using transaction code WE30 (IDoc Type Development) to check the definitions.
  Create/Activate Extension: If the extension does not exist, you will need to create it. If it exists but is not activated, activate it.
  Link Basic Type and Extension: Ensure that the basic IDoc type is correctly linked to its extension. This can be done in transaction WE30 by selecting the basic type and checking the extension settings.
  Transport Requests: If the IDoc type and extension were transported, check the transport logs for any errors. You may need to re-transport the objects or manually create them in the target system.
  Testing: After making the necessary changes, test the IDoc processing again to ensure that the error is resolved.
