Who Can Modify the AML/AVL and the Sourcing Status
Consider the following rules for making changes to the AML/AVL and the sourcing status.
If the user is a member of the Supplier Administrators group (with Read and Write permissions to the part), modifying the AML/AVL does not require a checkout of the OEM part, and the OEM part does not get iterated.
* 
A Supplier Administrator cannot modify the AML/AVL if the part is checked out to another user.
The icon for updating the supplier relationship is available only when the user has the "Modify" permission on the OEM part.
If the user is not a member of the Supplier Administrators group, the OEM part is auto-checked when the following properties are set to False:
When the system property com.ptc.windchill.suma.iterateOnAddRemoveAXL is set to False, the OEM part is auto-checked out during adding or removing AML/AVL relationships for users that are not members of the Supplier Administrators group. When this property is set to True, the part must be checked out by the user.
When the system property com.ptc.windchill.suma.iterateOnModifyPreference is set to False, the OEM part is auto-checked out during the sourcing status update for users who are not members of the Supplier Administrators group. When this property is set to True, the part must be checked out by the user.
* 
The history of changes is tracked even if the checkout of OEM parts is not required.
