The Accounts Receivable Payments selection uses the standard "browse" window found throughout the Rx-Universe system. 
From the browse screen the user can "Add", "Edit", "Delete" or "View" a payment. There are some restrictions for the "Edit" and "Delete" functions. If the selected payment record is for a past period (the payment date is equal or older than the last completed month), it cannot be modified or deleted.
Adding a new payment
Enter the account number for the payment. You can browse the account master database by pressing the search button next to the entry field.
Enter the Payment number. A Payment number will be automatically generated if the field is left empty. This is controlled via the "Special Numbers" database within Rx-Universe. There are several Special Numbering sequences that can be used to automatically generate a payment number, select the one best suited to your labs operation. The special numbers that will be checked to generate a payment number are as follows and will be searched in sequence for a potential match; "ARPMT", "CREDIT" and "INVCE".
Note that the Payment number needs to be unique. It is the key of reference that is used in the invoice database for the customer orders, therefore it cannot be a duplicate of an order number, or a debit note or credit note.
Enter the payment date. Note that a warning will be displayed if the date is in the future. Older dates are allowed, if they are within the current period (date is not older than or equal to the last completed month).
Enter the payment reference, this field automatically defaults to "Payment", but can be changed by the user.
Enter the document number. This would normally be the check number, deposit number, etc.
