SO user exit
Iam trying to create user exit using <b>MV45AFZB</b> for SO.
When user tries to create new sales order using VA01,
i want to check whether the <b>MATERIAL</b> is within the warranty. If the material is within the warranty, i want to give the message.Can any one tell me, for this requirement which subroutine i have to use?
FORM USEREXIT_CHECK_VBAK USING US_DIALOG
FORM USEREXIT_CHECK_VBAP USING US_DIALOG
or any other?
I want to check in the <b>creation mode</b>(VA01)
