  The SAP error message FDT_EXPRESSIONS850 indicates that there is an issue with a mapping parameter in your SAP system, specifically that a numeric parameter has been assigned an invalid value. This error typically occurs in the context of data transformation or mapping processes, such as those used in SAP Data Services or SAP Process Integration.
  Cause:
  The error can be caused by several factors:
  
  Invalid Data Type: The parameter is expected to be numeric, but the value provided is either non-numeric or out of the acceptable range.
  Incorrect Mapping: The mapping configuration may have been set up incorrectly, leading to the assignment of an invalid value.
  Parameter Positioning: The position of the parameter in the mapping may not correspond to the expected order, leading to confusion in value assignment.
  Data Source Issues: The source data may contain unexpected or malformed values that do not conform to the expected numeric format.
  
  Solution:
  To resolve the error, you can take the following steps:
  
  
  Check Parameter Values:

  Ensure that the values are within the acceptable range defined for those parameters.
  
  
  
  Validate Data Types:

  Review Mapping Configuration:
  
  Go through the mapping logic to ensure that the parameters are correctly positioned and that the mapping is set up as intended.
  If using a graphical mapping tool, check the connections and ensure that the correct fields are being mapped.
  
  
  
  Test with Sample Data:
  
  If possible, test the mapping with a small set of sample data to isolate the issue. This can help identify if the problem is with specific data entries.
