@melton-jason, What I did:

• if the user enters a cat # that has no prep, a warning will be displayed, the user will be able to click on continue without preparation
• if the user enters a cat # that has some type prep with no preps available, a warning will be displayed, the user will be able to click on continue, the interaction dialog with the rows will open without the prep type unavailable
• if the user enters two cat #, one with some available prep types, one with nothing available, a warning will be displayed, the user will be able to click on continue, the interaction dialog with the rows will open without the prep type unavailable and without the second cat #
• I think keeping this current new string makes more sense

(even though in my opinion, the current behavior in prod is perfectly fine)

@emenslin ,

Because that dialog let you know that there is nothing available for #42562 and that at least one prep type for #2 as nothing available, those 2 will not be represented in the second dialog as we now filter the unavailable ones
