• What is the cause and solution for SAP error message OPP_CORE013 - Conversion of XML response to ABAP structure failed ?

  The SAP error message OPP_CORE013, which states "Conversion of XML response to ABAP structure failed," typically occurs during the processing of XML data in an ABAP program. This error can arise in various scenarios, such as when interfacing with web services, handling XML data, or processing responses from external systems.
  Causes:
  
  Schema Mismatch: The XML response does not conform to the expected structure defined in the ABAP program. This can happen if the XML schema has changed or if the response is not formatted correctly.
  Data Type Issues: There may be data type mismatches between the XML elements and the corresponding ABAP data types. For example, if an XML element is expected to be a string but contains numeric data, this can lead to conversion errors.
  Malformed XML: The XML response might be malformed or contain invalid characters, which can prevent successful parsing and conversion.
  Encoding Issues: If the XML response uses a different character encoding than expected, it can lead to conversion failures.
  Missing Fields: Required fields in the XML response may be missing, leading to incomplete data structures in ABAP.
  
  Solutions:
  
  Check XML Structure: Validate the XML response against the expected schema. Ensure that the structure, data types, and required fields match what the ABAP program expects.
  Debugging: Use debugging tools in SAP to inspect the XML response and the corresponding ABAP structures. This can help identify where the conversion is failing.
  Error Handling: Implement error handling in your ABAP code to gracefully manage unexpected XML responses. This can include logging the raw XML response for further analysis.
  Adjust ABAP Structures: If the XML response has changed, update the ABAP structures to match the new format. This may involve modifying data types or adding new fields.
  XML Parsing Tools: Utilize SAP's built-in XML parsing tools (like SXML or SXML_DOCUMENT) to handle XML data more robustly.
  Encoding Verification: Ensure that the character encoding of the XML response matches what your ABAP program expects (usually UTF-8).
