  The SAP error message FDT_EXPRESSIONS630: Unnamed parameter not supported typically occurs in the context of using expressions in SAP's Form Data Technology (FDT) or when working with Smart Forms or Adobe Forms. This error indicates that there is an issue with how parameters are being defined or used in the expressions.

  Check Parameter Naming: Ensure that all parameters in your expressions are named correctly. Instead of using unnamed parameters, explicitly define each parameter with a name.

  Instead of using:
  (param1, param2)
  Use:
  (name1 = param1, name2 = param2)
