Component Item Cannot be a Phantom Item Error

[hziyali]

Hello,

I made an addon and am trying to create a production order from order recommendation. I have an error that is below:

The properties of my items are:

ItemCode : "M1" ,Inventory and Sales Item, Planning method: MRP - Make

ItemCode : "M2" ,it's only Sales Item, Planning method: MRP - Make,

ItemCode : "M3" ,Inventory, Sales and Purchase Item, Planning method: MRP - Purchase

And the product tree M1 --> M2 --> M3

What is the reason of this error? When I try to create production order of M1 on standard MIP without my addon it works succesfully.
