• What is the cause and solution for SAP error message CNV_PE_IF_RT043 - For receiver-like fields only sender-like fields allowed ?

  The SAP error message CNV_PE_IF_RT043 indicates that there is a mismatch in the data mapping between sender-like fields and receiver-like fields during a data transfer or conversion process. This error typically occurs in the context of data migration or transformation scenarios, particularly when using SAP's data migration tools or conversion programs.
  Cause:
  The error arises when the system encounters a situation where it expects a sender-like field (a field that is being read from the source system) but instead finds a receiver-like field (a field that is intended to be written to the target system). This can happen due to:
  
  Incorrect Mapping: The mapping configuration between the source and target fields is not set up correctly.
  Data Type Mismatch: The data types of the fields do not match, leading to confusion in the mapping process.
  Field Compatibility: The fields may not be compatible in terms of their characteristics (e.g., length, format).
  Configuration Errors: There may be issues in the configuration of the data migration tool or program being used.
  
  Solution:
  To resolve the CNV_PE_IF_RT043 error, you can take the following steps:
  
  
  Check Mapping Configuration:
  
  Review the mapping between the sender and receiver fields in your data migration tool or program.
  Ensure that sender-like fields are correctly mapped to corresponding receiver-like fields.
  
  
  
  Verify Data Types:
  
  Check the data types of the fields involved. Ensure that they are compatible and that any necessary conversions are handled appropriately.
  
  
  
  Field Characteristics:
  
  Ensure that the characteristics of the fields (length, format, etc.) are compatible. Adjust the field definitions if necessary.
  
  
  
  Review Transformation Logic:
  
  If you are using transformation logic (e.g., ABAP code or transformation rules), review the logic to ensure it correctly handles the data types and mappings.
  
  
  
  Consult Documentation:
  
  Refer to the SAP documentation for the specific data migration tool or program you are using. There may be specific guidelines or requirements for field mappings.
  
  
  
  Testing:
  
  After making adjustments, perform a test run of the data migration or conversion process to ensure that the error is resolved.
