Creating blueprints by ID?

I'm trying to generate bps as articles, but the only thing I get is the empty plan with no use with this id: -1887162396 in any BP.

Does anyone know how to generate the new BP?

 

I also need in ID Blueprint's

 

Code:

Item item =ItemManager.CreateByItemID(-1887162396); // Create the blueprint item
item.blueprintTarget = itemId // Set the target item ID as the blueprint target
