How to access change Request OG__CO

Hi Experts,

I have noticed in MDG 7 that Change request OG_CO was supplied with business activity OG. Is this an actual request that can be created or is it just a grouping of the entities?

We have a requirement to create Profit and Cost Centers with the same change request but I am not sure how the posting will work because obviously the Profit Center must exist in ECC before we post the Cost Center.

Thus can one request do both simultaneously and if it is possible how do you access this change request.

Your feedback will be highly appreciated.

Thanks and best regards

Riaan
