Please have a look at this,
When I create new slip like this:
The result is:

The above result is absolutely correct but It will be very useful if the new payment page after creating payslip contains all the data be it description, tracking code and number of line item same as was in Payslip except Qty & Rate intead in Unit Price put the Total of Amount of Payslip.
All the items Only under Earnings tab will be replicated against Employee Clearing Account in Payment Page while deductions and contribution figures shall be ignored.
