AET Generated field values are not saved.

Question

Hi Gurus,
I have created two AET fields on the screen (marked below) and that should store values in table CRMD_CUSTOMER_H. When I create a new service request and enter the values and save, AET field values are not saved. Again, when I edit the same service request and enter the values and save , AET field values are saved on the database.
While  debugging  I found that, relationship BTHeaderCustExt does not exist for the first time and second time onward its appearing. Due to this, data is not being saved at first time (Line no 27 : current is empty).
When tried to create realtionship using create_related_entity , it throwing exception cx_crm_genil_model_error.
Please advice me the soution for the same.
Regards,
Anand

Answer 1

there should be a context node at your view level. Please check ON NEW FOCUS method is implemented or not.
If not, you can implement that method with below code.
    DATA: lv_collection TYPE REF TO if_bol_bo_col,
          entity        TYPE REF TO cl_crm_bol_entity.
*   get collection of dependent nodes
    entity ?= focus_bo.
    TRY.
        lv_collection = entity->get_related_entities(
               iv_relation_name = 'BTHeaderCustExt' ).
        IF lv_collection IS NOT BOUND or lv_collection->size( ) = 0.
          IF entity->is_changeable( ) = ABAP_TRUE.
            TRY.
                entity = entity->create_related_entity(
                 iv_relation_name = 'BTHeaderCustExt' ).
              CATCH cx_crm_genil_model_error cx_crm_genil_duplicate_rel.
*               should never happen
            ENDTRY.
            IF entity IS BOUND.
              CREATE OBJECT lv_collection TYPE cl_crm_bol_bo_col.
              lv_collection->add( entity ).
            ENDIF.
          ENDIF.
        ENDIF.
      CATCH cx_crm_genil_model_error.
*       should never happen
        EXIT.
      CATCH cx_sy_ref_is_initial.
    ENDTRY.
    me->set_collection( lv_collection ).
