  The SAP error message SIW048 indicates that there is a problem with the uniqueness of an intermediate data type name within a mapping in SAP Process Integration (PI) or SAP Process Orchestration (PO). This error typically arises when you have defined multiple intermediate data types with the same name in a mapping, which can lead to confusion and errors during the execution of the mapping.
  Cause:
  
  Duplicate Data Type Names: The most common cause of this error is that you have defined two or more intermediate data types with the same name in the same mapping.
  Namespace Issues: If you are using different namespaces, it is possible that the same name is being used in different contexts, leading to ambiguity.
  Incorrect Mapping Configuration: Sometimes, the mapping configuration might not be set up correctly, leading to conflicts in data type definitions.
  
  Solution:
  
  Check Intermediate Data Types: Review the mapping configuration and check all the intermediate data types defined. Ensure that each intermediate data type has a unique name.
  Rename Duplicate Data Types: If you find duplicate names, rename them to ensure uniqueness. This can be done in the mapping editor where the data types are defined.
  Review Namespaces: If you are using namespaces, ensure that the data types are correctly defined within their respective namespaces to avoid conflicts.
  Revalidate the Mapping: After making changes, revalidate the mapping to ensure that the error is resolved.
  Check for Inherited Types: If you are using inherited types, ensure that the base types do not have conflicting names.
