Hi Ya,

I just want to check I've got your question correct.

You are wanting to change the value of a variable in your catalog item, based on which order guide is displaying the item, during the request process i.e. when a user is filling out the item details before a RITM is created.

P.S. If my suggestion helped then please mark as helpful and/or correct so other community members can benefit from this information.
