Problems with adding account to existing user

[Janine Hannibal]

Hi,

I have an existing user (batchko) who has come back to use SNF with a 
new company. I first added the new account and project (9VAV550) into 
the system. Then I tried to replace his existing account 1WXA676 with 
the new account 9VAV550, but it said that the account 1WXA676 did not 
exist. So, I then tried to just add the account 9VAV550 to the user's 
list of accounts but it also said that 9VAV550 did not exist when I had 
just entered it.

Any ideas on how I can replace the old account (1WXA676) with the new 
account (9VAV550)? Any assistance you can provide is greatly appreciated.

Thanks,
Janine
