How to get the content of context nodes in other components ?

Hi,

I have a MAIN-Component, which holds all my data in the context with many different nodes.

And I have some other components a, b, c, d, ...

In the component MAIN I have a node called 'MASSNAHME' which I want to share with component a and b.

How can I do that ? It only works for me to share the node over external context mapping for component a but not a AND b.

I also tried to get a component usage to get the content over abap coding interface->context->root_node->child_node...

but this was not working for me, the nodes were always empty.

Any hints are appreciated..

Thanks in advance
