Webdynpro application with multiple DCs

Question

Hi,
I have an application where it is splitted in to multiple DCs for the team development. Now at runtime there are navigation happenening across DCs, means on click of a button in view1 of DC1, it needs to call view2 of DC2. What is the best way to achive it? Is there a way to direcly call a DC component at runtime?
Any help?
regards,
Sujesh

Hi Sujesh,
First I want to point out, that DCs do not communicate with each other. DCs are designtime constructs which comprise development entities with runtime and/or designtime relevance. Inter-DC calls are Inter-DC-object calls.
Is your question related with the problem how to communicate between Web Dynpro components of separate DCs? To answer this question you must know how to develop Web Dynpro applications based on using separate DCs. This is done by defining DC-usage relations based on Public Part Definitons. When these DC-relations are correctly set up you can use Web Dynpro entities from other child DCs in a parent DC as if these entites would be contained in the parent DC. The runtime dependencies (sharing references etc.) are defined automatically.
Regarding your "Best Design" question I reply with a simple but quite effective principle: <b>"Favor DC-separation of Web Dynpro development entities!":</b>
- Separate Web Dynpro components in separate DCs
- Separate Web Dynpro Models in separate DCs
- Separate Local Dictionaries in separate DCs
- Separate Web Dynpro Component Interface Definitions in separate DCs
- Seaprate reusable Web Dynpro components in seaprate DCs.

P.S.: Look at my corresponding tutorial dealing with multi-component application design: https://www.sdn.sap.com/irj/sdn/downloaditem?rid=/library/uuid/bd0e0401-0801-0010-aaab-d0e1742da383
