F4 help before save - ALV Grid in Module Pool

poornimal_nathan — Mon, 22 Aug 2011 13:10:50 GMT

Hi,

I am calling an ALV Grid using CL_GUI_A;V_GRID. When I create a new record, I need F4 help for a particular field based on the entries in 2 other fields. Thing is I can't use DATA_CHANGED event coz then I won't be able to display the F4 button. And F4 option doesn't pass the data that has been changed(ER_CHANGED_DATA table). So frustrating. Can anyone help me plz???

Thanks in advance,

Poornima L Nathan

Why dont you try method CL_GUI_ALV_GRID's CHECK_CHANGED_DATA.

This method refreshes the data in the internal table of the GRID.

Hi ,

i think you are missing one params while registering your F4 fields..

ls_f4-register = 'X'.

ls_f4-getbefore = 'X'.

ls_f4-chngeafter = 'X'.


Documentatin of SAP program *BCALV_EDIT_08*
*   1b. If the value range in your f4 help depends on other
*       values of cells that are input enabled, set the
*       GETBEFORE parameter.

now you can use row_indx no to read your internal table
