External Comp. Context - mapping not completed

Dear SDN,

I have been trying ALL the ways to link Interface Contexts between 2 components.

But nothing has worked.

The error is always the same: "The Mapping to Node COMPONENTCONTROLLER.1.CASE_LIST Has Not Been Completed"

Does anyone have any idea about what can be the problem here?

There is some dynamic programming in the components. Is this the problem? (once I heard it could be).

I have already read ALL the threads about

. mapping in the Component Usage,

. Comp. A and Comp. B...

. 'Input-Element (ext.)' checkbox,

. etc.. etc..

I have tried all the proposals.

But nothing worked for me.

Please, can anybody give me any piece of suggestion?

I will be grateful for any attempt of helping!

Thank you all.

hi fabio,

please check the url for component usage.

https://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/library/uuid/2e71ce83-0b01-0010-11a4-98c28a33195f

it is not required to set in and out plugs,

suppose you have two component A and B, and you want to use/call component B from component A.

just click on component A, and in used component tab enter name of component B. when you save it comes in component usage in left side.

now if you want to pass some value from A to B, then create same node in both the component, and in component B, set node property to interface node and input.

in component A, after adding comp B in used component, it start displaying it in compo A. now create external binding of that node , as we do in ALV, and you are able you use and call component B in component A,

furthermore, you can call interface methods from comp B in comp A.

if you need some Example please tell.
