AR Invoice - Multiple lines for Receivables Account

When creating customer invoice in AR, we create multiple revenue lines, each having its own CCID depending on the memo line used.

Our requirement is to create receivables distribution also at CCID level in same ratio as revenue. We have tried to create SLA rule as well, but it is still creating only 1 receivable line.

Please advise why. We are on Oracle 12.1.3

Our business wants to report aging by line of business and we are unable to do that since we have 1 cost center at receivable account level. We cannot create separate invoices for each customer for each business line
