Between versions 10.1.3 and 2009 R2, it is no longer possible to edit an item which is related as AFFECTED to a request belonging to another project, even though the item is not being checked out / edited in relation to this request. (CM rules are off.)

Instead, you will get an error message saying "Error: Item <itemspec> is not part of a valid related project for request <Request>"

Below are the steps to recreate this problem: -

a) Create item x in project A

b) Export item x to project B

c) Create request Z in project B

d) Relate item x to request Z

e) Remove item x from project B

f) Edit item x from project A

Expected result: -

You will be able to check out / edit the item.

Actual result: -

You get the error message below.

Edit Item - COR0005695E Error: Item PRODUCT:X TXT.BASE-SRC;A#1.0 is not part of a valid related project for request REQUEST_1

The AFFECTED mode for relating an item to a request should not be regarded as a dependency relationship.
