Understanding Changes to a Business Unit
You can change the business unit portion of the account number on many accounts at once by globally changing the business units. For example, you can change business unit 3 to business unit 4 for all object and object.subsidiary accounts.
To change the business unit on multiple accounts, the current business unit and the future business unit must exist in the F0006 table and must belong to the same company. If they do not, the system displays the company for the old business unit and for the new one, but it does not update them.
Accounts that already exist in the new business unit are not updated with the new business unit number because this action would cause duplicate accounts. For example, if you are renumbering business unit 1 to business unit 10, and account 10.1110.BEAR already exists in the F0901 table, the system does not update account 1.1110.BEAR to business unit 10.
The Change Business Units program (P09812) updates the F0901 table with each account.
