problem saving bill-to-party addrress in VA02

Hello,

when i change the address of the ship-to-party by adding another name or add other details, VA02 gives the status message that says that the document has been saved.

However if I open it again, i get a pop up about a message in my inbox. the detail of the message is the the address does not exist & & &.

and in the document, the address has not been saved.

I'm getting this since we moved to ECC6 from 4.6C

Anyone having an idea how to solve this problem?

THanks in adavance.
