contrat date of item with billing plan changed after credit release ,why

[Former Member]

one item of a sale order is a special item with billing plan ,when i use VKM3 to release this order , just the special item 's contract date changed ,why ?

how does a item with billing plan cause the contract date change . why the other's haven't changed?

Thank you !

I find that all the items with billing plan are in the same situation, the contract date of them will be changed after credit release
