F-90 acquisition error

Question

I use transaction type 100 for F-90, if I enter inter-company vendor, it pops up below message:
Transaction type not possible (Posting to affiliated company)
Message no. AA390
Diagnosis
For the current document, you specified either implicitly (via the customer/vendor), or explicitly (with a manual entry), that this posting is to an affiliated company. In this case, Asset Accounting requires you to use special transaction types.  This enables the system to separately identify such transactions.
Procedure
Check the line items that you have already entered, and the transaction type you entered.
if third party vendor, it is ok, so what's the t-code I use to copy  transtion type 100 and made change, thanks

Answer 1

Hi,
please check the following:                                                                               
A transaction type is used which post against affiliated company      
although no affiliated company has been indicated.                    
  Solution: Please use another transaction type or enter a            
  affiliated company.                                                                               
A transaction type is used which doesn't post against affiliated      
company although a affiliated company has been indicated.             
  Solution: Please use another transaction type or don't enter a      
  affiliated company.
