Development and marketing of SAP EP solutions - any licenses required?

Hi

Not sure which forum to post this in, so - maybe Coffee Corner is a good start 😊

My question is about the licensing required to development and marketing small add-ons / extensions for SAP Enterprise Portal.

Is it possible for the individual developer to develop and market small add-ons for EP in Java WDP, making use of a trail EP installation?

Do you need a special license for this (to develop commercial products)?

Maybe like a [SAP NetWeaver Developer Subscription|https://www.sdn.sap.com/irj/scn/subscriptions/development?refer=subscriptionslandingpage], or the [SAP Composition Subscription|https://www.sdn.sap.com/irj/scn/subscriptions/composition?refer=subscriptionslandingpage]?

Reading up on the [Subscriptions FAQ|https://www.sdn.sap.com/irj/scn/subscriptions/software-faq#q-4-5], and it is not very clear:

Can I use my developed add-ons, extensions, developments, or modifications in a production environment?

In order to run your add-ons, extensions, developments, or modifications in a production environment, you need to purchase the applicable license from SAP. SAP customers or partners who already have an applicable license can use SAP NetWeaver in a production environment.

So-

"SAP customers or partners who already have an applicable license can use SAP NetWeaver in a production environment"

I'm not expecting to run the SAP NetWeaver Developer/Trail version you get with the subscription in a production environment - the question is would any prospective buyers of your developed add-ons be able to run these in their (fully licensed) NetWeaver / EP production environments?

(I feel this FAQ is not answering its own question correctly).

Purchasing a full EP license is a little out of my budget, and even the two developer subscriptions mentioned above are only available in Germany & the USA (and I reside in neither of which).

Any suggestions from the guys & girls of the Coffee Corner?

Thanks!
