Issue
Class doesn't allow us to process the distribution reinvestment for a platform/wrap account.
We receive the message:
"The Holding Account you have selected may not have reinvestments"

Cause
The platform/wrap account can only has one unit, so the system doesn't allow us to process the distribution reinvestment.
Resolution
- Process a normal distribution
Navigate to Fund Level > Transactions > Fund Income > Distribution - Cash

- Process a cash in transaction to increase the cost base of this platform asset
Navigate to Fund Level > Transactions > Browse Bank Statements

- Match the distribution transaction processed in Step 1 and the cash-in transaction processed in Step 2
