Adobe Document Services Licensing in SAP

I have been asked about Adobe Document Services (ADS) licensing in SAP last weekend (during my interview session :-P)

By the way sir, here is the answer if you are reading this. Below lines are copied from the SAP Note 750784 – SAP Interactive Forms: Licenses.

Using the tool Adobe LiveCycle Designer and the Adobe document services, and using pure print forms (not interactive) is part of the license of the relevant SAP solution (including SAP NetWeaver).
If the following three criteria apply to you, you must purchase an additional license from SAP for your SAP Interactive Forms:
• You create templates for interactive forms.
• You create your own customer-specific interactive form templates or change an interactive form template delivered by SAP by adding further interactive fields or changing the data binding of existing interactive fields to the back end.
(Such modifications are over and above cosmetic changes in form templates delivered by SAP such as adding your own logo or static texts, and are therefore subject to license.)
• You use interactive forms in a production system, that is, end users fill in generated PDF forms during business operations.
Note that the additional license also affects interactive forms used by SAP partners (independent software vendors – ISV), who deliver these forms as part of their products developed on the SAP NetWeaver platform.
The license for SAP Interactive Forms is an official SAP license. For further details, consult your contact person in your local SAP sales office.
