Hi Luis,

you access the data from the UI layer via the context nodes. So you need to identify which context node of your view the relevant attribute belongs to, most likely something like Detail, BuilHeader or so. Attrbute should be FIRST_NAME for the first name field.

Tip: At runtime, put the cursor into the field and press the F2 key. A popup will show up with component name, view name, context node and attribute.

To access the attribute value in the coding you need to go access the the context node via the TYPED_CONTEXT attribute of the view. From the context node you could either access the attribute value via a getter (you may need to generate a specific one) or by accessing the current entity and go from there.

So e.g.

me->typed_context-><your_context_node_name>->get_<your_attribute>( ) for the getter access

or

lr_ent = me->typed_context--><your_context_node_name>->collection_wrapper->get_current( ). lv_val = lr_ent->get_property( '<your_attribute>').

Best regards

Hi, I finally found the method to get te value of the attribute in the context node,

Example:

L_PERSON is the instance of the one node context.

L_back is a string.

CALL METHOD L_PERSON->IF_BSP_MODEL_BINDING~GET_ATTRIBUTE

EXPORTING

• ATTRIBUTE_REF =

ATTRIBUTE_PATH = 'STRUCT.LASTNAME' "<- For example

• INDEX =

• COMPONENT =

• NO_CONVERSION_EXIT = 0

RECEIVING

VALUE = l_back.

I hope this will help!

Thanks N' Best Regards.
