Hi Neelam,

Did you put the entity into change mode before setting the property ?

You can do it by using lr_entity->switch_to_change_mode( ).

You can also check with this statement if it is really in change mode and then proceed with setting the value.if lr_entity->is_changeable( ) = abap_true.

Hi Vinod,

Thanks for you reply, i tried your statement, still it is not updaing the status.

below code i have written.

           lr_customer_h_ent->switch_to_change_mode( ).

          if lr_customer_h_ent->is_changeable( ) = abap_true.
           lr_customer_h_ent->set_property_as_string( iv_attr_name = 'ZZ_status'  iv_value     = 'A' ).
          endif.

here when i am executing the above statement is_changeable() .....is returning value abap_true = 'X' in debugging mode.

but still it is not updating the value.

when i open the same record second time and try to execute the code...second time it is updating the status. 

i don't know where it is wrong.

pls provide some help.

Regards,

Neelam

Hi Neelam,

You will use publish_current method of the entity if still it is not working

then use modify method() of cl_crm_bol_core.

here is some piece of code which can help you for understanding.

--------------------------

    DATA:
    lr_btadminh      TYPE REF TO cl_crm_bol_entity,
    lr_btsubjectset  TYPE REF TO cl_crm_bol_entity,
    lr_btsubject     TYPE REF TO cl_crm_bol_entity,
    lr_core          TYPE REF TO cl_crm_bol_core.


* get current BTSubject
  lr_btsubject ?= me->typed_context->btsubject->collection_wrapper->get_current( ).
  IF lr_btsubject IS BOUND.

* delete old BTSubject

*   get parent (BTSubjectSet)
    lr_btsubjectset ?= lr_btsubject->get_parent( ).
*   delete it
    lr_btsubject->delete( ).
    me->typed_context->btsubject->collection_wrapper->remove( lr_btsubject ).
    lr_core ?= cl_crm_bol_core=>get_instance( ).
    lr_core->modify( ).


* create new BTSubject and append it
    lr_btsubject ?= lr_btsubjectset->create_related_entity( 'BTSubjectAll' )."#EC NOTEXT


    me->typed_context->btsubject->collection_wrapper->add( iv_entity = lr_btsubject iv_set_focus = abap_true ).
  ENDIF.

* get BTAdminH
  lr_btadminh ?= me->typed_context->btadminh->collection_wrapper->get_current( ).
  CHECK lr_btadminh IS BOUND.

* read dependant objects again
  me->typed_context->btbosset->on_new_focus( lr_btadminh ).

-----------------------------------

Hope it will help you .

Hi Durga prasad,

thanks for reply,  

actually when i am calling set_property_as_string() method to set the new value for status field ....it is not setting the status....

in debug mode after execution of the statement if i check the status, same old status only showing.

but when i open the same record again 2nd time it is updating the status from same method...

i don't know where i am wrong.

help me on this.

Hi Neelam,

Please check the value ZZSTATUS of the status in getter method it should be alphabet  like 'U' 'S' as you are updating it with 'A'. if not please check you status key values

Otherwise check this yes this is data refresh issue you updated the status but it is not reflecting in the entity since you need to publish_current() method with will refresh the current data from buffer to the entity and is still you will face the same issue then use modify() method this will refresh the root entity some time it might be the issue.

But above all please

Please check with those method and let me know if you need more help.

Hi Durgaprasad,

thanks for reply,

here i am updating the field from Child relation entity level. so i can't see the get method for this attribute.

below is my code:

lr_current->get_properties( IMPORTING es_attributes = ls_inthist ).
       lr_inthist = lr_core->get_root_entity( iv_object_name = 'BTOrder'
                                               iv_object_guid = ls_inthist-guid ).

lr_customer_h_coll ?= lr_inthist->get_related_entities_by_bpath( iv_bpath_statement = './BTOrderHeader/BTHeaderCustExt/*' ).

lr_customer_h_ent ?= lr_customer_h_coll->get_current( ).

         if lr_customer_h_ent is bound.

  lr_customer_h_ent->set_property_as_string( iv_attr_name = 'ZZ_status'  iv_value     = 'A'  ).

here above statement not changing the attribute value.

But when i coming back from overview page to result list page and again go to overview page and try to set the attribute when clicking on oca button this  time with same record if i try to set it...the same above method is updating the status. i don't know why this behaviour...every record i am able to change the status only 2nd time,

Pls help me on this.

Thanks,

Neelam
