Check Table Values.

[amit_khare]

While going through this standard SAP program 'BCALV_GRID_EDIT'. I came through this interesting piece of code for populating field catalog of an OO ALV.

<b>clear gs_fieldcat.

gs_fieldcat-fieldname = 'CURRENCY'.

gs_fieldcat-ref_table = 'SFLIGHT'.

gs_fieldcat-edit = 'X'.

gs_fieldcat-checktable = '!'.

gs_fieldcat-auto_value = 'X'.

append gs_fieldcat to gt_fieldcat.</b>Can Somebody please explain me the use of this EXCLAIMATION MARK , in the checktable value in details?

Amit,

gs_fieldcat-checktable will check checktable value for table SFLIGHT.

Hi

I think it will give the check table for SFLIGHT.

Hi Amit.

Welcome to SDN.

The answer is quite simple.

The domain of the field 'checktable' contains a value table DD02L for checking the valid tables.

The value '!' is used to check whether a valid entry exists in the value table DD02L.

I mean here we are checking whether the table SFLIGHT exists in DD02L.

Abdul
