Hi all,

For a Manufactured Part, we can define several Structure Alternates (*, 1, 2...), which is a very useful feature. Normaly we would define the default product structure, the most used one, in Structure Alternate *.

We are increasingly using this feature to define alternative ways to manufacture the parent part based on changes on supply chain, etc. 

When we have many Structure Alternates available, MRP, Shop Order creation, etc,… will take the default * Structure Alternate. If we want to choose another option, we can do so manualy (not very efficient) or use the Structure Lot Size “trick”,… where we specify that any Lot bigger than “zero” should be manufactured using the Structure  Alternate “x” (1, or 2 or whatever). 

Basicaly, we are using the Structure Lot Size feature to point towards the Structure Alternate we want to select by default. 

Problem: if the parent part is Planning “P” type, Phantom, there will not be any need to manufacture it, and therefore the Structure Lot size trick will not work (as there will not be any Lot to manufacture). So, we can not trick the MRP to choose any other alternative different from the default * ….

Is there a way to choose the Structure Alternate we want to use more effectively? And Phantom-proof? 

Thanks in advance,

Best regards,
