CRM Web Client (ChaRM) - Approval Procedure Greyed out (Security)

Hi

I am testing my ZMCR (Change Request) Process in CRM Web Client UI and the Approval Procedure field is greyed out:

I have added SAP_ALL and SAP_NEW to the user and this resolves the issues...so it's definitely security related.

Here is my Approval config:

And here is ZAPPROVE in Status Management config:

What authorizations do I need to add to a role for this to show properly? And do I need to add "Auth Codes" in status management above? (last screenshot). I also tested using IT000003 (instead of ZAPPROVE) which is standard....also doesn't show either.

I am also having similiar issues with the Project field (in my first screenshot) which is also greyed out.

I have gone through the Solman 7.1 Security Guide (500+ pages) but it doesn't mention much about this.

Thanks
Shaun
