ChaRM: Reassign Change Document

Hi

We are on Solman 7.1 SP12 and are trying to reassign a change document (ZMMJ) to another project.

It works fine for me but I have a high level of authorizations.

For other users of ChaRM, they click on Edit (in CRM Web Client) > Reassign Change and then a search box appears.

However, when they click on search they cannot view any projects (when I click search I can).

I've searched everywhere online but can't find what authorization is missing.

Can anyone help?

Thanks
Shaun
