Access Value node

DATA: lr_mixed TYPE REF TO CL_BSP_WD_MIXED_NODE,

lr_entity TYPE REF TO CL_CRM_BOL_ENTITY.

lr_mixed = me->typed_context->your_context_node->collection_wrapper->get_current( ).

lr_entity ?= lr_mixed->if_bsp_wd_ext_property_access~get_model_node( ).

lv_value = lr_entity->get_property_as_string( iv_attr_name = 'DATE' ).

If the attribute is a value node you can access it directly.

lr_mixed = me->typed_context->your_context_node->collection_wrapper->get_current( ).

lv_value = lr_mixed->get_property_as_string( iv_attr_name = 'DATE' ).

The context node that you are using is a mixed node, so from this node you need to get model node so that you can cast the entity into CL_CRM_BOL_ENTITY.

Here's the sample code:

DATA:

lr_mixed TYPE REF TO cl_bsp_wd_mixed_node,

lr_entity TYPE REF TO cl_crm_bol_entity,

lr_child TYPE REF TO cl_crm_bol_entity.

lr_mixed = me->typed_context->node_name->collection_wrapper->get_current( ).

lr_entity ?= lr_mixed->if_bsp_wd_ext_property_access~get_model_node( ).

lr_child ?= lr_entity->get_related_entities( ).
