Hi Sneha,

It is very simple. You have to write code only in event handler of that button, nowhere else.

You have the header entity in the event handler. Just use get_related_entity method (or get_related_entities once or multiple time) to get that entity on which you want to set some value. Use SET_PROPERTY method to set the value (LOW). And do not forget to trigger MODIFY of CL_CRM_BOL_CORE after SET_PROPERTY.

Hi Sagar,

Can you please send me the code to be written in event handler.
with declarations.

Hi Sneha,

for exact code, you have to tell me the component and the view name where you have placed the event handler and the view and the context node which has the attribute which you need to set.

Without knowing these details, i can only provide you following snippet of code. Header of the transaction is in lr_header.

data: lr_core type ref to cl_crm_bol_core,

      LR_ENTITY TYPE REF TO cl_crm_bol_entity.

* Get the BOL Core instance

lr_core = cl_Crm_bol_core=>get_instance( ).

* read entity to be updated

lr_entity = lr_header->get_related_entity( iv_relation_name = '<relation name>' ).

* Lock entity for changes

if LR_ENTITY->lock( ) = if_genil_Boolean=>true.

*Change the fields

LR_ENTITY->set_property( iv_attr_name = 'ZZRISK' iv_value = '<key for value LOW>' ).

* update core

LR_CORE->modify( ).

endif.

Hi Sagar,

Component Name: AIC_CMCR_H

Custom Controller: ZAIC_CMCR_H/ZCustom

Views

1.  AIC_CMCR_H/AICCMCRHeaderEF

    View controller class:   Implementation Class ZL_AIC_CMCR_AICCMCRHEADER_IMPL

       Context class:  Implementation Class ZL_AIC_CMCR_AICCMCRHEADER_CTXT

        Context nodes: BTCUSTOMERH

            Implementation Class ZL_AIC_CMCR_AICCMCRHEADER_CN05

              Attribute: EXT.ZZFN_AI_RISK

2. AIC_CMCR_H/AICCMCROverview

    View controller class: Implementation Class ZL_AIC_CMCR_AICCMCROVERVI_IMPL

        Context class: Implementation Class ZL_AIC_CMCR_AICCMCROVERVI_CTXT

          Event handler: EH_ONEH_ONCLICK

There is not context nodes or attributes in overview.

Only event handler is present here.

I have done this coding in event handler.

But i am getting below dump

Entry parameter of method CL_CRM_BOL_ENTITY->SET_PROPERTY contains value ZZFN_COMPL_RISK, which is not allowed.

DATA: LR_CTX           TYPE REF to CL_SRQM_RFC_BSPWDCOMPONEN_CTXT,

           LR_CUCO1      TYPE REF TO CL_AIC_CMCR_BSPWDCOMPONEN_IMPL,

           lr_entity1           TYPE REF TO IF_BOL_BO_PROPERTY_ACCESS,

            lv_guid             TYPE crmt_object_guid.

LR_CUCO1 ?= me->comp_controller.

IF LR_CUCO1 is bound.

   LR_CTX = lr_cuco1->typed_context.

   LR_ENTITY1 = LR_CTX->btorder->collection_wrapper->get_current( ).

   lv_guid = LR_ENTITY1->get_property_as_string( IV_ATTR_NAME = 'CRM_GUID' ).

ENDIF.

LR_ENTITY1->SET_PROPERTY( IV_ATTR_NAME = 'ZZFN_COMPL_RISK'

                                                     IV_VALUE          = 'L' ).

Please help by providing solution.

I guess data declaration is wrong.

May be lr_entity is of wrong data type.

But i am not getting the data type to declare for that.

try this.

DATA: LR_CTX           TYPE REF to CL_SRQM_RFC_BSPWDCOMPONEN_CTXT,

      LR_CUCO1      TYPE REF TO CL_AIC_CMCR_BSPWDCOMPONEN_IMPL,

      lr_core type ref to cl_crm_bol_core,

      LR_ENTITY TYPE REF TO cl_crm_bol_entity.

* Get the BOL Core instance

lr_core = cl_Crm_bol_core=>get_instance( ).

* read entity to be updated

LR_CUCO1 ?= me->comp_controller.

check LR_CUCO1 is bound.

   LR_CTX = lr_cuco1->typed_context.

   LR_ENTITY ?= LR_CTX->btorder->collection_wrapper->get_current( ).

check LR_ENTITY is bound.

   lr_entity ?= lr_entity->get_related_entity( iv_relation_name = 'BTOrderHeader' ).

check LR_ENTITY is bound.

   lr_entity ?= lr_entity->get_related_entity( iv_relation_name = 'BTHeaderCustExt' ).

* Lock entity for changes

check LR_ENTITY is bound.

if LR_ENTITY->lock( ) = if_genil_Boolean=>true.

*Change the fields

LR_ENTITY->set_property( iv_attr_name = 'ZZFN_COMPL_RISK' iv_value = 'L' ).

* update core

LR_CORE->modify( ).

endif.

Hi Sagar,

Thank you very much for your solution.

Now it is working.

But it is getting filled even when field is not empty.

I mean LOW value has to fill only when the button is clicked and field ZZFN_COMPL_RISK is empty.

can you please let me know for this.

Thanks in advance.

Hi Sneha,

Put a check before calling the set_property method as below:

check LR_ENTITY->IF_BOL_BO_PROPERTY_ACCESS~GET_PROPERTY_AS_STRING( IV_ATTR_NAME = 'ZZFN_COMPL_RISK' ) is initial.

Hi Sagar,

Thank u.

It is working...

Hi Sneha,

you can also use the GDC Attributes to access the instance in the overview method.

Below i am trying to access and set the attibutes of a service request when the one of the buttons of the overview page is clicked.

using the below sample code:

DATA: LR_GDC         TYPE REF TO IF_CRM_UI_DATA_CONTEXT.

  DATA: LR_SERV_REQ        TYPE REF TO CL_CRM_BOL_ENTITY.

          LR_STATUS_SET  TYPE REF TO CL_CRM_BOL_ENTITY,

          LR_STATUS_CUR  TYPE REF TO CL_CRM_BOL_ENTITY.

LR_GDC = CL_CRM_UI_DATA_CONTEXT_SRV=>GET_INSTANCE( ).

    IF LR_GDC IS BOUND.

      LR_SERV_REQ ?= LR_GDC->GET_ENTITY( IF_ICCMP_GLOBAL_DATA_CONT_CON=>GDC_CURRENTREFBT ).

    ENDIF.

    IF LR_SERV_REQ IS NOT BOUND.

      LR_SERV_REQ ?= LR_GDC->GET_ENTITY( IF_ICCMP_GLOBAL_DATA_CONT_CON=>GDC_CURRENTSERVICEREQUEST ).

    ENDIF.

    LR_ORDER_H = LR_SERV_REQ->GET_RELATED_ENTITY( IV_RELATION_NAME = 'BTOrderHeader' ).

    IF LR_ORDER_H IS BOUND.

      LR_ACTIVITY = LR_ORDER_H->GET_RELATED_ENTITY( IV_RELATION_NAME = 'BTHeaderActivityExt' ).

    ENDIF.

you need to navigate to the correct relation of the service request in this case its status.

lr_status_set = lr_order_h->get_related_entity( 'BTHeaderStatusSet' ).

        IF lr_status_set IS BOUND.

          lr_status_cur = lr_status_set->get_related_entity( 'BTStatusHCurrent' ).

          IF lr_status_cur IS BOUND.

            lr_status_cur->get_property_as_value( EXPORTING iv_attr_name = 'ACT_STATUS'

                                                  IMPORTING   ev_result  = CUR_STATUS ).

here you can set the attribute value to what you want.

lr_status_cur->switch_to_change_mode( ).

            lr_status_cur->set_property( EXPORTING iv_attr_name = 'ACT_STATUS'

                                                   iv_value     = LS_ZCONFIG-STATUS ).

Hi,

In the event handler read the context to which that field belongs.

Then use the method SET_PROPERTY of your entity to set "LOW".

Lets say my context is CONTEXT_A

LR_ENTITY ?= ME->TYPED_CONTEXT->CONTEXT_A->COLLECTION_WRAPPER->GET_CRRENT( ).

IF LR_ENTITY is bound.

LR_ENTITY->SET_PROPERTY

EXPORTING

IV_ATTR_NAME = "FIELD_A"

IV_VALUE           = "LOW".

ENDIF.

Note: Provide the KEY of dropdown as value and not description.

Thanks

Deepak

Hi Deepak,

Thanx for your information.

But i have 2 views one header view and another Overview.

The field name which has to be set to LOW is ZZRISK.

This field present in header view ->context node->attribute->zzrisk.

But my event handler is in overview.

So when i call get property its showing an error as class is not defined.

Please guide me how to resolve it.

[former_member249090]

Hi,

My problem got resolved now. Values LOW is getting displayed when the particular field is empty.

But now i am struck with another problem.

I have done coding to display the value LOW in header view atribute but event handler is in overview.

Now Value LOW is getting filled everytime when it is initial.

But my requirement is that value should get filled only when button is clicked.

Please tell me how to find whether button is clicked or not.

Please help.

[deepak_sharma_sap]

HI,

You can do as below:

1. Enhance the Custom Controller and Create same context nodes as HEADER and Overview.

2.  Bind them to the HEADER and OVERVIEW views.

Now in EVENT handler of your button , first read the CUSTOM CONTROLLER:

LR_CUCO ?= me->get_custom_controller( ' Name of your custom controller' ).

if LR_CUCO is bound.

lR_ENTITY = lr_cuco->typed_context->header_view->collection_wrapper->get_current( ).

CALL METHOD LR_ENTITY->if_bol_bo_property_access~set_property

IV_ATTR_NAME = 'ZZRISK'

  IV_VALUE  = 'LOW'.

ENDIF.

Thanks

[former_member249090]

Hi Deepak,

Thanx for your Suggestion.

But can you please tell me in the set method of context node attribute, how to identify whether event handler is triggerrred or not .

Because event handler is triggerring after this set method execution.

I am setting the values in Set method so i need to differentiate whether button is clicked or not.

If button is clicked event handler will trigger.

So please let me know any code to be written in set method  to identify button is clicked and event handler is triggered.

Thankx in advance.

[deepak_sharma_sap]

You don't need to use the set method of field .

Since you have bind the nodes to custom controller , so on event handler of your button now you should have the HEADER and overview entities.(By reading from Custom controller , as mentioned in previous post).

There you read the applicable node and then set the corresponding field.

Thanks

[former_member249090]

Hi Deepak,

i have created the custom controller with name zcustom and i have binded with the header view context attributes  to which i need to set the values.

i do not have any context node in overview so i have not binded.

now lr_cuco is bound.

But when i write below statement i am getting error saying, typed_context is not defined as DATA.

So i tried to declare it in the IMPL class of overview.

But it is showing that already typed_context is present.

So can you please tell me the solution for this.

• lR_ENTITY = lr_cuco->typed_context->header_view->collection_wrapper->get_current( ).
