In CU51, the opening screen has the option to enter an ECM or a date for the effectivity of a change. It defaults to today's date. For this example, we are using today's date, not an ECM. My expectation is that if I delete component A and add component B using CU51, when I look at CS63 that component and that component alone will have the effectivity date of today. If it were a phantom, I would expect its components to have today's date as well.
Our engineer used CU51 to change a component. When we look at CS63, numerous unrelated components also show today's date as the effective date and have his user id as the person who changed them. In particular, a major assembly unrelated to his change had it's effectivity date changed. This causes problems because the effectivity date can determine whether or not an item is included as a component in a planned order.
Can anyone explain how the effectivity date is changed while using CU51? What is the expected behavior?
