input data from used component

[Former Member]

Hi Experts,

I have a main component A. I have 2 used compoents inside it i.e. B and C. I have created an interface node in component A and mapped it to B and C. I amm able to pass data from A to B and C.

The problem is, i want B and C to pass data to A also. How can i do this.

I have tried External input element but i couldnt get that to work. Basicall i want all A, B and C to read and modify the same node.

Thanks for your Help.

Regards,

Pris.

Sloved by using interface events.

Hi,

You need to do external context mapping like we do while using ALV.

Try this.

Lets say B has node NODE_B and C has NODE_C.

A has two corresponding nodes NODE_A_B and NODE_A_C.

1.  Mark node NODE_B as interface node and External Input Element

2.  Mark node NODE_C as interface node and External Input Element

3. Create usage USAGE_B and USAGE_C in component A along with INTERFACECONTROLLER.

4. Now from the navigation available in the left panel You will see ComponentUsages.

5. Click on that, navigate to InterfaceController of USAGE_B.

6. Here, create Component Usage for Component Controller of A.

7. You will be able to see the nodes NODE_A_B and NODE_A_C on the right and NODE_B on left. Create Mapping from NODE_A_B to NODE_B here. This way your node NODE_B in comp B will be able to receive data from NODE_A_B of comp A.

8. Repeat corresponding steps for USAGE_C.

Hope this helps.

Hello Prisford,

Map that interface node to the views in B & C and specify the usage of this interface view in the views so when you set the values is the context attribute it will automatically available in component A context

that context node you also need to map to view present in compnent A where you want to access data.
