Hi every one
I have an issue and it’s about a part that was Manufacturing and I have changed the Part type to Purchased but I can not Retire the Manufacturing part.
It should be noted that it has just 1 revision and the phase-out field is empty because I don’t want to Phase out the Part.
I have a question about how can I Retire a part with default alternate in Product structure which is converted from manufacturing to purchase.

I’ll be appreciate if you help me.
