Petty Cash and Custody Process

Hello Dears,

I have a question regarding the Petty Cash and Custody Process. Currently, some custodial funds are released via check payments, and we need to allocate these to specific employee custodies. At present, we use bank account transfers, with each employee identified as a separate bank account and a unified GL Account Segment to track the balance of each custody. However, the bank account transfer process does not include the check serial numbers defined for the payables payment documents.

Is there a solution to control the check serial numbers, or can the process be amended to meet our requirements?
