Custom Cash basis Accounting SLAM for Secondary Ledger

Summary:

Hi, We have a client requirement where in we need to create a Custom Cash basis Accounting SLAM for the Secondary ledger as the out of the box seeded Cash Basis SLAM has multiple pre-requisites which cannot be enabled in the Client instance.
The Client does not want Multifund accounting enabled

To use the Cash Basis Secondary Accounting Method for Receivables, the following conditions must be met:

• The Receivables Business Units must have the Enable multifund accounting option enabled in Receivables System Options.

Hence we have referred the Revenue Journal line in Receipts, but it is not populating the Revenue account as well as the amount from AR invoice.
