Solman 7.1 - ChaRM creating changes WITHOUT Change Request

Hi all

This is more of a process related question.  I see in the CRM Web Client UI, there is a link to create "normal changes" (SMMJ) and "urgent changes" (SMHF).

In the past (Solman 7.0) we ALWAYS create a Change Request, get this approved, and then the normal change or urgent change is added to the approved CR (this is the only way to create a change).

I'm just wondering if a CR should always be created first (and approved) in 7.1 before a change (normal or urgent) is added to this? If so, why can you create a normal/urgent change direct from Web Client without a CR???

Can someone share a situation when one may need to do this?  I'm just not sure if I should remove this link from the Web Client.

Thanks!!
