Interface nodes

Hi Experts

I have a requirement where i have to pass the value from one component to another.

I tried using interface nodes but the values are not getting trasferred to the other component .I used display messages to check thn came to knw the component controller of using coponent is getting called many times thats means the component is getting instantiated evry time thats why nodes data dint get retained .Tried using interface methodasalso but the problem remains the same .

The using component is further getting used in many components .

Is there global constants concept in WD ABAP whose value dint get changed evn when the component is instantiated again.

Please suggest.

Thanks

Monika
