VA03 -> Document flow -> select sales order and press "Display document" button
System displays VA03 screen.
ZVA03 -> Document flow -> select sales order and press "Display document" button
System displays ZVA03 screen. Not VA03!!
ZVA03 = a new transaction for customer based on VA03 with a transaction variant screen.
I have debagged and found system calls 'VA03' when pressing "Display document".
But system seems to hold the transaction variant screen and shows ZVA03.
I don't know the reason why system doesn't show 'VA03' screen despite of a standard function of Document flow.
How can system hold the transaction variant of ZVA03? (SAP memory? or anything else?)
Our customer nervously wants to get the reason for this symptom.
I have checked SAPMV45A / 4001 in SM51 and not been able to specify the coding about this transaction variant.
Could anyone advice me?
