ALV - refresh data after value is selected from input help

Question

Hello,
I have input ALV where after I enter material number and press enter, the logic goes ahead and populates description column by utilizing ON_DATA_CHECK event.
Is is possible to trigger some kind of event after the value is selected from search help without hitting enter key?
When the user done with using search help and clicks on material number that he needs, the value is populated in ALV cell, and this is where I need some event trigger to fire the logic to get description without pressing enter.
Thanks,
Alex

Answer 1

Alex, in that case, the alternative you have is to:
- Create a Z structure where you have all the table fields
- Bind the Standard DDIC search help to the Material ID (Importing) and the Description (Exporting)
- Create the whole context node in WD referencing that DDIC structure.
The important thing here is that the context node as a whole must reference the structure in order for this to work, not just the fields affected. This may not be possible or desirable in certain cases.
If you do this, the Description will be populated by the SH through its returning parameter, so you wont have to do anything in WD to retrieve it as for the manual input + Enter cases.
Here you have some help on SHs parameters:

Hope this helps.
