You can also use the Service Call Wizard. It has the nice addition that it will generate a matching Context for the interface of your function module (or any service target it supports):

Here is a video on the subject as well:

Hi,

Just Call a function module in any event that has to triggered.

for ex call FM in WDDOINIT.

Pass the importing values to the FM and set the Node attribute from the exporting values of FM. Now the node will have the FM returned values.

Into Component Controller means you want the data in the Context of a component Controller

Analyze the Function Module what it is returning?

If it returns a Structure create a Cotnext Node of the Structure Type with cardinality 1..1

If it returns a table create a context node of the table line type with cardinality 0..n

Call the function Module in the Component Controller's WDDOINIT method if you need it on initialization of the component

use the code to put the data in your context of the component controller

data : lr_node type ref to if_wd_context_node.

lr_node = wd_context->get_child_node( '<name of the node>' ).

lr_node->bind_table( <internal table returned after the Funciton module call>' ).

Use Pattern to call the function Module or use statement CALL FUNCTION as in normal reports or module pools

you can simply execute that function module in WDDOINIT method or at any point of time you wish it.

after execution of that function, you can set it to corresponding context node / attributes.
