  The SAP error message WRF_WLAY_XI_PROXY090 indicates that a supplemental field in a specific structure is not initialized when it is expected to be. This error typically occurs in the context of SAP's Advanced Planning and Optimization (APO) or related modules where data structures are being processed, particularly in the context of integration scenarios.
  Cause:
  The error message suggests that a required supplemental field (denoted as &1) in a structure (denoted as &2) is not empty (i.e., it contains some data) when the system expects it to be empty (or "initial"). This can happen due to several reasons:
  
  Data Integrity Issues: The data being processed may not conform to the expected format or rules, leading to unexpected values in the supplemental fields.
  Configuration Errors: There may be a misconfiguration in the system that causes the supplemental fields to be populated incorrectly.
  Custom Development: If there are custom enhancements or developments, they might be populating these fields incorrectly.
  Integration Issues: If data is being transferred from another system (e.g., through an interface), the data mapping might not be set up correctly.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check Data: Review the data being processed to ensure that the supplemental field is indeed supposed to be empty. If it should be empty, investigate why it is populated.

  Consult Documentation: Refer to SAP documentation or notes related to the specific structure and supplemental fields to understand their intended use and any known issues.
