Hi Kohei,

It is set based on the connected part.

For the connected part, if there is inventory part on the site and no engineering part, then it is set based on the part type. If part type is Purchased, then supply option is Purchase; if Manufactured, then Shop Order.

If there is engineering part, and no inventory part, then it depends on the combination of Provide Code and Planning Method on engineering part.

If there are both EP and IP, then it depends on the combination of both above.

You can see some examples below. 

The related fields on EP: 

I hope this helps.

Best regards,

Hi Nebahat,

Thank you for your reply. 
I got your point and verify this system behavior.

An addition to how supply option is set:

When Std Planned Item is set to Yes in Product Structure and then in Project Deliverables Copy Product Structure functionality is used, then this overrides the Supply Option value set by Engineering Part.

nkurt,

Thank you for your message on this question.

I got it.
