Customer recon account change

Question

Hello Friends,
Our client had a requirement of changing the recon account for customer.
Customer A (recon account 100) already had line items posted from last 2 years, these line items are cleared also.
Now business wants the recon account for this customer A to be G/L#200. Along with that the reporting in balance sheet for this customer is required to be in recon GL 200.
In order to achieve this we did the following:
1. We made the balance of the customer account zero by transfereing the balance to temperory GL account. (Accounting document # 1200001 created)
2. Changed the recon account in customer master from 100 to 200.
3. Made reversal entry, i.e., transfered the balance from temperory GL account to customer account. (Accounting document # 1200002 created)
4. In balance sheet now the balance is transfered to recon account 200.
But now there is a problem, the customer statement has two open items (documents 1200001 & 1200002) when we are clearing these open items in the customer the impact created earlier with step 3 is getting reversed i.e., the balance from recon account 200 is getting nullified and its going back to recon account 100.
We just want to clear the customer open item how can we do this?
Please suggest.
Regards

Here is the official SAP help on the subject:- 
Hello,
You should run balance sheet adjustment program after any reconciliation account change. 
The system performs any adjustments required due to the change of reconciliation accounts or G/L accounts. The items from the old reconciliation accounts are allocated to the new accounts.  Since you cannot post to the reconciliation accounts directly, the postings are made to temporary adjustment accounts. 
These adjustment accounts should be displayed along with the relevant reconciliation account in the balance sheet. The postings are then reversed after the balance sheet has been created.  The program for sorting the payables and receivables makes the necessary adjustments automatically. This means that you have to define the adjustment account numbers and the posting keys for these postings in the system.  On the balance sheet key date the open items from the old reconciliation account are allocated to the new reconciliation account using adjustment accounts. This allocation is carried out automatically when you create a sorted list of receivables and payables using report SAPF101.
You should only run this program if your new reconciliation account is classified differently from the original in your FS. e.g.. AR to Intercompany accounts. It will just reclassify the existing balance. The line items will not be transferred. If not then no need to run the program at all.
