• What is the cause and solution for SAP error message CNV_PE_IF_RT044 - For structured receiver only structured sender allowed ?

  The SAP error message CNV_PE_IF_RT044 indicates that there is a mismatch in the data structure between the sender and receiver in a data transfer process, specifically when using structured data. The error message states that for a structured receiver, only a structured sender is allowed. This typically occurs in the context of data migration or data transfer scenarios, such as using the SAP Data Services or SAP Landscape Transformation (SLT).
  Cause:
  
  Mismatch in Data Structure: The sender is not structured (e.g., it could be a flat file or a simple data format), while the receiver expects a structured format (e.g., a hierarchical or nested data structure).
  Configuration Issues: The configuration settings for the data transfer may not be correctly set up to handle structured data.
  Data Mapping Errors: There may be issues in the mapping of fields between the sender and receiver, leading to incompatibility.
  
  Solution:
  
  Check Data Structure: Ensure that the data being sent from the sender is indeed structured. If the sender is a flat file, consider converting it to a structured format that matches the receiver's expectations.
  Review Configuration: Go through the configuration settings in the data transfer tool you are using (e.g., SAP Data Services, SLT) to ensure that both the sender and receiver are set up to handle structured data.
  Adjust Mapping: If you are using a mapping tool, verify that the mapping between the sender and receiver is correctly defined. Ensure that all required fields are mapped appropriately.
  Test with Sample Data: Create a small sample of structured data and test the transfer to see if the error persists. This can help isolate the issue.
