• What is the cause and solution for SAP error message WGDS_PROCESS201 - &1 is not a valid string boolean value. ( See type WGDS_BOOLEAN_STRING ) ?

  The SAP error message:
  WGDS_PROCESS201 &1 is not a valid string boolean value. (See type WGDS_BOOLEAN_STRING)
  
  Cause:
  This error occurs when a value passed to a parameter or field expected to be a string boolean (i.e., a string representing a boolean value) does not conform to the allowed values defined by the data type WGDS_BOOLEAN_STRING.
  In SAP, the data type WGDS_BOOLEAN_STRING typically expects a string that represents a boolean value, such as:
  
  'X' or 'x' for TRUE
  '' (empty string) or ' ' (space) for FALSE
  
  If the input value is anything other than these expected values, the system raises this error.
  This often happens in scenarios involving SAP Gateway Data Services (GDS) or when processing OData services where boolean values are passed as strings.
  Where it happens:
  
  When processing or mapping boolean values in string format.
  During data import/export or service calls where boolean parameters are passed as strings.
  In custom code or standard SAP code that uses the WGDS_BOOLEAN_STRING type
