Service Contract Invoice Date to be 1st of every month

Hi Team,

We have implemented Service contract for one of our client and facing the issues in implementing the below business process.

The client wants the Invoice Date for all the Billing Schedule to be First of every month and the same Invoice date should be printed on the AR Invoice after we run the SCMB program and interface to AR. For example

Contract duration is 3 months and is monthly billing contract ( Total value $1200 ) , so the billing schedule should look like this ( below )

Start Date of Contract - 01-NOV-2016

End Date - 31-JAN-2016

Billing schedule:       Seq       Invoice Date             Bill From                    Bill To                                Interface Date
