  The SAP error message FDT_EXPRESSIONS129 indicates that there is an issue with the configuration of a data object in the context of using the "multiple match" mode in the SAP FDT (Form Data Tool). This error typically arises when the result data object is not defined as a table, which is a requirement for using the "multiple match" mode.
  Cause:
  The error occurs because:
  
  The result data object you are trying to use in your expression is not defined as a table type.
  The "multiple match" mode is designed to handle multiple entries, which necessitates that the result data object be a table to accommodate multiple rows of data.
  
  Solution:

  Review Expression Logic:
  
  Review the logic of your expression to ensure that it is appropriate for the "multiple match" mode. If you do not need to handle multiple entries, consider using a different mode that is suitable for single matches.
  
  
  
  Test Changes:
  
  After making the necessary changes, test the configuration to ensure that the error no longer occurs and that the desired functionality is achieved.
