Invoice Corection : Subaccount Credit Memo is different from Subaccount original Invoice

I've noticed that when reversing an Invoice, the system creates a Credit Memo, and the subaccount on the Credit Memo is the same as the original Invoice. This is automatic and doesn't require any further configuration except for editing the subaccount on the Credit Memo.

Dear ​@nhatnghetinh , thanks for the answer. in my case, FA team using Screen Correction : Correct Invoice. It will be generate one invoice and one Credit Memo.   
 

Hi ​@Johanes 

I observed that when using the "Correct Invoice" feature, the system creates a Credit Memo and a New Invoice, and the sub-account on the Credit Memo and New Invoice is the same as the original invoice.

​@nhatnghetinh , Many thanks for u. 

I just found a new correlation (maybe). The different subaccount appears only on invoice lines that have an SO relationship. 
this is my INvoice
