Use the Valid P/O Numbers Selection window to create parameters to use to validate purchase order numbers entered on a sales order. When a purchase order (P/O) number is entered for a customer in Sales Order Entry, the number is validated against the number you enter here.
To create parameters for validating a customer P/O number:
From the Maintenance menu, select Customer to display the Customer Maintenance window.
In the Customer field, enter the customer' name to display the customer record.
Select Orders > Valid P/O Numbers to display the Valid P/O Numbers Selection dialog box.
Enter one or more of the following:
A P/O number.
A string of characters followed by a right square bracket, for example, ABC]. The P/O number must start with this string of characters.
A string of characters preceded by a left square bracket, for example, [ABC. The P/O number must end with this string of characters.
A string of characters proceeded by a left square bracket and followed by a right square bracket, for example, [ABC]. The P/O number must contain this string of characters somewhere in the number.
Note: Purchase order numbers cannot contain a tilde (~).
Repeat the process to add additional P/O numbers or parameters.
To delete an item from the list, select the item and press Alt-Delete.
When you have finished adding P/O numbers or parameters, save your changes and exit the dialog box.
