You need to pay for additional languages. It is somewhat expensive and the payment frequency can be annual or monthly, depending on the choice. There are no extra costs beyond the standard license and implementation fees.

I am not aware of pricing or licensing, as I was not part of the purchasing or evaluation process.

SAP JAM has lots of possibilities. My client is using it for a very specific matters, like social collaboration.

There are other examples where JAM is used in a broader, integrated way for HR. For example, it is the landing page for all the SuccessFactors functions and is used as the internal HR community within the company for all employees.

When considering SAP JAM, I would suggest buying it together with other modules within a package, similar to what my customer did.
