Which field can identify that a line item of a SO is been deleting in Exit.

Hi guys,

When we delete a line item in a sales order in VA01 or VA02, the system will call the user exit USEREXIT_CHECK_XVBAP_FOR_DELET. But the deleted line item will not be removed from XVBAP at once and XVBAP-UPDKZ still is 'I', anybody can tell me which field can identify that the processing line item was deleted or not?

Thanks in advance!

Tim
