Hi Narendra,

I hope your value is not updating into the Table and if this is the case then try using this systax for updating,

UPDATE dbtab FROM TABLE itab or

UPDATE dbtab FROM wa.

This works successfully only if there are value which you need to update. Its always better to use Modiffy statement since it inserts if no values were found or updates if there is a Match.

MODIFY dbtab FROM wa or

MODIFY dbtab FROM TABLE itab.

Hope this works.

Thanks and Regards,

Prashanth
