Cut off period for sales order settlement

Question

Dear Expert,
Client using SAP from last  13 years. Client implemented MTO with valuated stock and activated the COPA.
Now we are re implementing the COPA. since go live(from last 13 years ) they are not doing any sales order settlements and not using COPA.
In sales order RA key(Requirement class) is assigned and Settlement type is 'FUL'.
Now client has decided to use COPA and going to live with new structure on September 1 2014.
I have do the below changes
1. Removed RA key(Not required as per business requirement)
2. Changed settlement type from 'FUL' to PER., here i am having some questions. Client don't want to settle previous orders(before September). as per business requirement they will use one sales order for long time (3 to 4 months). after going live client will settle the sales orders at that time system will consider all sales orders. How can i avoid selection of all sales orders. i want to settle only sales orders having transactions during one month (September)
To avoid this problem now its self i am moving this changes to Production client (RA key removed and Settlement type change), still i am not confident i will get as expected, because at the time of Sales order settlement system will consider all old sales orders.
Can anyone please suggest beat way to handle this issue...
Thanks.

Hi Chandra,
Check the Below SAP Note
174815
- Selection parameter in VA88 or RKO7VA88
Symptom
During the settlement of sales and distribution documents with Transaction
VA88 or report RKO7VA88, you can only select according to the SD document number
or the sales organization.
For example, you cannot select by plant or SD
document type.
Other Terms
VA88
Reason and Prerequisites
The problem occurs due to a previous program design.
Solution
With the attached advance correction, you can also select according to the
plant or the SD document type in report RKO7VA88.The previous restrictions apply
for Transaction VA88.
To correct the error in advance, proceed as
follows:
1. First implement Notes 174502 and 182735.
2. Using Transaction SE11, add field VBAUART (data element AUART) to
structures LKO74 and RKASS. Activate the structures.
3. Add the following parameter to the interface of function module
SD_DOCUMENT_OBJNR_GET (Transaction SE37):
a) Import parameter:I_WERKS (reference field VBAP-WERKS) and I_AUART
(reference field VBAK-AUART). Both parameters should be indicated as
'optional'.
b) Export parameter:E_WERKS (reference field VBAP-WERKS) and E_AUART
(reference field VBAK-AUART).
4. Implement the source code corrections.
5. Maintain the text elements for report RKO7VA88 (Transaction SE38, Goto
--> Text elements --> Selection texts):Text 'Sales document type' for
VBAUART and 'Plant' for WERKS.
Afterwards, also implement Note 210011.
