Reversed Note Item(Down Payment) but still appear as open item

Question

Hello experts,
we were having trouble with reversed down payment.
we have 2 system in our landscape: one dv1 other dv2
in dv1 :
1. create dp request from so resulting(VF01) :
_______________________Doc No.   Type  ............................ Clearing Doc
___-- fbl5n : 1 open item      : xxxxxx1 RV      .............................
2. cancel dp request with VF11
_______________________ Doc No.   Type  ............................ Clearing Doc
___-- fbl5n : 1 cleared item : xxxxxx1 RV      .............................yyyyyyyyy
in dv2 :
1. create dp request from so resulting(VF01) :
_____________________Doc No.   Type  ............................ Clearing Doc
___-- fbl5n : 1 open item : xxxxxx1 RV      .............................
2. cancel dp request with VF11 :
______________________Doc No.   Type  ............................ Clearing Doc
__ -- fbl5n : 1 open     item : xxxxxx1 RV      .............................
__________1 cleared item : yyyyyy   ZB     ............................. yyyyyyyyy
the billing type(VOVA) and posting key(OB41) setting on both system have similar value. Can anyone point to us where the setting went wrong in second system? Because of that anomaly the system show the dp request as open item on fbl5n or sales document flow.
thanks in advance.
Best regards,
Henry

Answer 1

further investigation, when we checked the clearing document found in dv2(clearing document which is not referenced by the billing), we found out the document type is 'S' so it was still noted item. so the conclusion is when we cancelled a billing which corresponding accounting document's type is S(noted item) , system created a "clearing" accounting document which type still is S(noted item) too but with negative amount.
but in dv1, it works normally, when billing cancelled system created clearing document which type is C(clearing document).
can someone advise us on this? thank you.
