ALV - Validate Data after User-Command (SAVE)

Former Member — Mon, 28 Jul 2008 11:37:27 GMT

Hi Everbody !

I created a quite nice editable ALV-Grid, that works almost fine.

The only problem I have and don't understand is the valditation in the PAI-Module of my dynpro, e.g. at the 'SAVE'-Command, if the 'ENTER'-Button wasn't pushed before.

In case of an error, the protocol shows up, but the false entry in alv is overwritten by the old content.

I call the method MY_ALV->CHECK_CHANGED_DATA.

What have i to do then?

Can anybody explain this to me?

Thanks a lot!

Sabrina

You need to Make use of the DATA_CHANGED event.

Check the sample program : BCALV_EDIT_03

It is for Verification of modified cells

Hi!

Thanks for the immediate reply!

The Data-Changed-event is not the problem:

i registered it that way and implemented the handling inclusive error-protocoll.

CALL METHOD my_ALV_->REGISTER_EDIT_EVENT

EXPORTING

I_EVENT_ID = CL_GUI_ALV_GRID=>MC_EVT_ENTER.

the user has to push 'ENTER' to check the changed data on one rush.

But if the user only pushes 'SAVE' or something beyond the alv-toolbar, the pai-module will be processed.

So, i get the method alv->CHECK_CHANGED_DATA, to check the entries.

That works well, the protocoll is displayed, but the wrong entry in Alv (which is normally marked as error) is overwritten by the old, correct content.
