User exist at loading start for shipment txn (VT02N)
May I know is there any user exist at loading start button for shipment transaction (VT02N)? As we need to include some logic to auto generate the value then populate that value into standard SAP fields ( external id field VTTK/EXTI1).
And can we direct update the output value from that user exist to standard SAP fields ( external id field VTTK/EXTI1) in VT02n transaction?
Pls help and advise.
