A/R Transaction File Rebuild

	This routine will sort and reconnect transactions (payments,
	invoices, etc) to each customer. In addition, the current
	balance of each customer is zeroed and re-added based on the 
	total of the activity for each customer.

			Removing Transactions

	Optionally you may choose to purge (remove) paid up activity
	prior to a cutoff date.

	Usually you would want to keep at least a years worth of
	activity. Base this on your needs for accessing prior sales or
	payment records of customers.

	In this day of large hard drives and fast computers, you may
	choose to keep years of activity with few consequences. So 
	normally use this option only if you have been advised to do so.

	You may remove unpaid activity, by using the master password to get
	here, then another option to purge ALL activity (paid or not) will
	appear on screen. This is useful for starting up another company using a
	copy of another A/R files.

			Re-calc YTD Billing

	Another option that is useful is to recalculate the YTD Billing
	for each customer. You can do this every January to start the
	year again. Or temporarily set it to a date range (ie 3 months)
	to examine paid sales in that period.

	NOTE - IF the Re-calc option is NOT there, you are on the YTD Ship to
	basis and must use AR menu option #7, then #3 to recalc the YTD Ship $.
