Special G.L Recon Account

Hi

I have a business case where requirement is as follows:

1. Customer normal Item (Recon Account Say ABC) is posted at time of billing.

2. Users need to track open items in customer normal items (say Post dated cheque recd from customers).

However, normal items should remain as open (SAP standard process for PDC is not applicable in this scenario).

I am proposing using a special G.L where Recon A/c (ABC) and Special G.L Account (also ABC) will be same for the Special G.L Indicator (Both will be customer recon account).

Just wanted to confirm if any issue will be there in this process or any better method is available.

Thanks in advance
