Value Check for ALV fields

[Former Member]

Hi,

I have a modifiable ALV for a name-value table. The ABAP types are strings respectively. In the name column the field names of a DDIC structure are displayed. In the value column a value can be entered. I also implemented a f4 help depending on the value of the name field. Now I also would like to have a value check, which is essentially working as the ALV value check for DDIC fields, i.e. if the user enters a wrong value for the DDIC field a little pop-up appears and the ALV cell is marked through red text.

Thanks a lot,

Thomas

Hi

Are you using OO ALV?

In this case see the demo program BCALV_EDIT_03.

FIELDCAT-FIELDNAME = 'BUKRS'.

<b>FIELDCAT-CHECKTABLE = 'T001'.</b>

You can use Checktable option in the fieldcatalog.

Hi,

If you are using OO ALV then Check this example <b>BCALV_EDIT_04</b>

here they have used some thing differently. if you use Checktable if you give wrong input then it will give Dump.

so they used

fieldcat-checktable = '!'. "this avoids check table check

and then they used their own checking.

just see the code.
