Help needed with F4 input selection

Former Member — Tue, 15 Apr 2014 06:34:12 GMT

I am working on a dynpro in which there is an input field and the F4 selection dialog displays all entries including delimited entries from a Z table. There is no search help object specified in the screen painter layout for the field. I have no idea how the list is populated and where to find the code. I need to stop delimited value being primed for input selection. How should I go about troubleshooting this? Thanks in anticipation.

Hello Ramprasad.

Simple. Just debug and see the flow.

If no search help is in screen painter, then a module would have been written under PROCESS ON VALUE-REQUEST.

Regards.

Hi Arun

I tried that. The code just passes through FM 'DD_SHLP_CALL_FROM_DYNP' and exits, displaying the selection window.

Check the values passed on to structure help_infos.

They look OK to me. Moreover there are no date fields in the structure for me to try and pass on so that delimited entries could be filtered out.

I am not sure about this FM's full functionality.

But using FM F4IF_INT_TABLE_VALUE_REQUEST, we can prepare an internal table filtered based on our requirements and then displayed.

Hi,

Please check on whether a search help is attached to the data element of the input field.

The system use a simple hierarchy to attach search-help to a dynpro field, look at this picture

(Source Hierarchy of Search Help Calls at help.sap.com)

So there may be no code to find, and the PROCESS ON VALUE-REQUEST (or POV) allows you to change the standard behavior.

Raymond
