ABAP code example for Function Module F4IF_FIELD_VALUE_REQUEST

The ABAP code below is a full code listing to execute function module F4IF_FIELD_VALUE_REQUEST including all data declarations. The code uses the latest in-line data declaration syntax but I have included an abap code snipet at the end to show how declarations would look using the original method of declaring data variables up front. This will allow you to compare and fully understand the new inline method. Please note some of the newer syntax such as the @DATA is not available until a later 4.70 service pack (SP8).

The below ABAP code uses the older none in-line data declarations. This allows you to see the coding differences/benefits of the later inline syntax. It may also be useful if you are using an older version of SAP as some of the newer syntax above, such as the @DATA is not available until 4.70 EHP 8.
