I have a Cashbook transaction linked to multiple invoices. How can I view the individual dissections?

Handy Hint 

Cashbook transactions linked to multiple debtor invoices will show the dissections as a summary rather than each dissection individually.
 It will also prevent the transaction from being edited.

To show each dissection:

Step 1

Go to Debtors

Step 2

Click on the Setup Tab and at the bottom untick "Show paid invoices as summary in cashbook".
