Search Help in Webdynpro For ABAP

[Former Member]

Hi Experts,

In my application I want to attach search help to a field. My problem is that table field for which I am creating search help contains duplicate values. I dont want those duplicate values. How can I achieve this?

I am using trfgr field of table T510.

Please help.

Thanks & Regards,

Hi Experts,

I have used Search Help Exit which is a function module . The exit is running correctly but the search help is not showing any entries in the hit list. I am not getting where is the problem. Please help.

Thanks,

Hi

You need to write your code under line if callcontrol-step = 'SELECT'

once you have done the data selection fill the result table using function module F4UT_RESULTS_MAP.

in parameters: source_structure = 'the table/view name in caps used as selection method in search help

shlp_tab = shlp_tab

record_tab = record_tab

source_tab = internal table which contains the data selected by you, without duplicate entries

shlp = shlp

callcontrol = callcontrol

This FM call will fill your search help with data in right manner

Hello,

The problem is with the structure name u passed to function module. Structure must be same as the line type of your internal table. in your case create a global structure 'ZTRFGR' in dictionary with only one field TRFGR and pass it to the function module instead of T510. It should be fixed,

Hi Experts,

Can Anybody tell me how to achieve search help exit to achieve my functionality?

Thanks in advance.

Have you read the online help for search help exit:

http://help.sap.com/saphelp_nw70ehp1/helpdata/en/cf/21ee52446011d189700000e8322d00/frameset.htm

A search help exit is basically a search help implemented via a function module instead of a single table or join data read. You write the logic in the Function Module to retrieve the data.

Another alternative is to use a freely programmed value help. Here you control both the data logic and visualization of the value help.
