Use patterns to require product and serial numbers adhere to a specific sequence and number of characters. For example, serial numbers from a particular vendor may always begin with the same letters, or have a hyphen in the middle. By specifying a pattern for these specific letters and hyphens, you can accept only serial numbers that adhere to the pattern during entry; others are rejected.
Note
Patterns are also used for Customer P/O numbers using the same method as below. See Specify a pattern for default customer P/O numbers

For Serial Numbers
- Serial Number Patterns may be set at any time using the procedure below in Assign a pattern
For Product Numbers
- Go to File > Company > Master.
- Click the Pricing/Costing tab.
- Set the New Product Number Patterns based on (V)endor or (P)roduct Line:
- V prompts you for a vendor prior to creating a new product.
- P prompts you for a product line before creating a new product.
Inform ERP will validate product code patterns; only products that match pattern requirements will be accepted.

- On the Setup page, click the Patterns tab.

- Click Add Matching Pattern.
- In the new row that appears, type the pattern using the Pattern key, below.
For example, a pattern of "T"3A"-"5N indicates that the number must begin with the letter T, followed by three letters, a dash, and ending in five numbers. An acceptable product or serial number that would match this pattern is TABC-12345.
