A question for the behavior of Item relationship between part and manufacturer part.

Hi Expert,

Would you please help one thing?

Part ItemType has a relationship with 'Manufacturer Part' ItemType and the relationship ItemType is 'Part AML'.
The behavior of 'Part AML' is 'hard float'. (the behavior of Part ItemType is 'float'.)
With this configuration, I created '10000' part. And then,

1) I linked 'MFN0001' Manufacturer Part to '10000' Part, saved and unlocked it. ('10000' Part: Version A, Generation 1).
2) I locked '10000' part and deleted 'MFN0001' from the part and linked 'MFN0002' to '10000' part.
Saved and unlocked it. ('10000' Part: Version A, Generation 2).

When I opened 'MFN0002', it links to '10000' part. (Version A, Generation 2.) which is correct.
The problem is that when I opened 'MFN0001', it still links to '10000' Part (Part Version A, Genration 1).
What we want is that when we open 'MFN0001', there is no link to '10000' Part (Part Version A, Genration 1) because we delete it from '10000' Part.

I thought it would be solved by changing the behavior of 'Part AML' to 'hard float'.
But, it isn't.

Would you please help how to achieve this?

Thank you so much in advance.

Regards,

Joseph
