BS,
Is there a mechanism where Customers are given access to a data view on the Internet ?. I see clicking on Customer forecast calls the Internet that isn't set up yet in my system.
There are many. For instance, in SCM, there is collaborative planning:
or more specifically
Also SNC?. Is this also an option worth considering ?. or would it be needless expense (licenses et al) for a poor client.
SAP licensing models and licensing fees vary dramatically for each installation. I couldn't possibly advise you what any required additional licensing would cost. For instance, if you already have APO/DP, you may already own the license for SNC. For such information, contact your local SAP account manager, he can advise you.
To me, collaboration is not a 'nice-to-have' feature; it is a big project with a big effort and cost, even ignoring the licensing costs. Personally, I don't think I would begin such a project unless my company had customers that were demanding such a solution.
If you are really serious about implementing some type of collaborative effort, and you are not experienced with such matters, the normal first step is to engage a consulting company with expertise in these areas, to perform an analysis for you.
