regarding an input field

Former Member — Tue, 01 Jul 2008 12:58:31 GMT

Hi,

AT SELECTION-SCREEN ON VALUE-REQUEST FOR

xxxxx

and

PROCESS ON VALUE-REQUEST

are not possible to use in a search help exit.

Which alternatives do we have if I need to e.g.

to call a function module regarding an input field

on the search help window ?

Regards

ertas

Hello Ilhan Ertas ,

You can check the below report logic :

Hello Ilhan Ertas ,

Sorry for the wrong posting . We have the Seach hep exit when we create Search help in SE11. Use that for your logic. Check the below documentation from SAP :

Search help exit

A search help exit is a function module for making the input help process described by the search help more flexible than possible with the standard version.

This function module must have the same interface as function module F4IF_SHLP_EXIT_EXAMPLE. The search help exit may also have further optional parameters (in particular any EXPORTING parameters).

A search help exit is called at certain timepoints in the input help process.

Note: The source text and long documentation of the above-specified function module (including the long documentation about the parameters) contain information about using search help exits.

Function modules are provided in the function library for operations that are frequently executed in search help exits. The names of these function modules begin with the prefix F4UT_. These function modules can either be used directly as search help exits or used within other search help exits. You can find precise instructions for use in the long documentation for the corresponding function module.

Hope this answers your question.

Thanks,

Greetson
