Why would item fulfillment look different for admin role and a custom role

Different default form?

No it’s same form for both the roles

Are the IF from different SO?Look back to the Sales Orders form customization to see if they have different Linked Forms.

No it’s from the same sales orders, it’s same item fulfillment. This is serialized item if that helps.

Is it specified on the Linked Forms or blank? Do the user Roles have different default forms? I would do more analysis of other So/If/items/users to see what’s driving it.

They both have same default form. There is linked form on so

Is the default available to the user Role?

it's blank
