Earlier, I was assuming that the fund sources for all products would be the same, so consolidated transactions like 

• Scenario 1) Disburse loan to a savings

Loan should: Debit Loan Portfolio
Savings should: Credit Savings Control

• Scenario 2) Transfer from savings to Loan

Savings should: Debit Savings Control
Loan Should: Credit Income from interest, income from fees, loan portfolio, income from penalty

• Scenario 3) Transfer from savings(a) to savings(b) where A is a withdrawal and B is a deposit

savings (a) : Debit a' Savings Control
savings (b) : Credit b's Savings Control

...

Also, such concerns may be purely developer issues and not a valid use case? Can somebody please have a look at the suggested consolidated postings and comment?
