There may be an instance when users save an Item Fulfillment and receive "Missing or invalid ship from phone number.".
Along with Shipping Integration, it is mandatory to have a Ship From phone number (your company's phone number). NetSuite prevents users from saving Item Fulfillment without a valid Ship From phone number.
Consider the following that may have caused the error:
- There is no phone number entered in Setup > Company > Company Information.
- The format of the phone number may be incorrect. Phone numbers can be entered in the following formats: 999-999-9999, 1-999-999-9999, (999) 999-9999, 1(999) 999-9999 or 999-999-9999 ext 9999.
- If Multi-Location Inventory is enabled, there might be no phone number entered on the location record under Setup > Company > Locations.
