BOL Programming(WebUI)

This document is aimed at understanding bol programming CRUD operation concepts in CRM WebUI.

Sample Code for BOL Creation : Create a Activity Transaction

DATA : lr_core TYPE REF TO cl_crm_bol_core.
TRY.

Sample Code for BOL Search : Search a Activity Transaction

Use CL_CRM_BOL_QUERY_SERVICE or CL_CRM_BOL_DQUERY_SERVICE class objects to search data.

DATA : lr_core TYPE REF TO cl_crm_bol_core.
TRY.
     lr_core = cl_crm_bol_core=>get_instance( ).

                               iv_low  = '*' iv_option = 'EQ'  iv_high = ' ').

*Execute Query and retrieve result
lr_result = lr_qs->get_query_result( ).

CHECK lr_result IS BOUND.

*Use Iterator to access entities in query result
lr_iter ?= lr_result->get_iterator( ).

lr_entity ?= lr_iter->get_first( ).

DATA : lv_guid TYPE crmt_object_guid.
WHILE lr_entity IS BOUND.

   "Perform Operations or Write
   Write:/ lv_object_id.

   lr_entity ?= lr_iter->get_next( ).
ENDWHILE.

Sample Code for BOL CHANGE OR UPDATE ENTITY

Scenario : To Modify or update a Business Object entities.

To update BOL entity , First we need to search using Search Object and get the entity object (Root object ) once we can the instance of Root object we can update the entity.

For Search : Use Above code as reference.

Data : lr_core type ref to cl_crm_bol_core.

    lr_core = cl_crm_bol_core=>get_instance( ).
     TRY.
         lr_core->start_up( EXPORTING iv_appl_name = 'ONEORDER'
                                      iv_display_mode_support = abap_true ).
       CATCH cx_crm_genil_general_error.                 "#EC NO_HANDLER

   lr_search_result_coll = lr_qs->get_query_result( ).

   IF lr_search_result_coll IS BOUND.
     lr_iterator = lr_search_result_coll->get_iterator( ).

   IF lr_iterator IS BOUND.
     lr_btorder = lr_iterator->get_first( ).

*Get the Entity of Activity Object
CALL METHOD lr_btorder->get_related_entity
   EXPORTING
     iv_relation_name = 'BTOrderHeader'
   RECEIVING
     rv_result        = lr_order_h.
CATCH cx_crm_genil_model_error .
ENDTRY.

lr_order_h->switch_to_change_mode( ).

*Locks are always set on root object.
IF lr_order_h->lock( ) = 'X'.
IF lr_order_h->is_changeable( ) = 'X'.

*Set property also locks the object entity if lock has not been set.
   lr_order_h->if_bol_bo_property_access~set_property( iv_attr_name = 'DESCRIPTION'
                                                       iv_value     = 'Melbourne' ).
*Modify BOL layer
   lr_core->modify( ).

lr_transaction = lr_core->get_transaction( ).
lv_success = lr_transaction->save( ).
IF lv_success eq abap_true. lr_transaction->commit( ).
ENDIF.
ENDIF.ENDIF.ENDIF.ENDIF.

Sample Code for BOL Delete   

* Use Above code for Entity Object

lr_entity ?= lr_result->get_first( ).
*
*Lock and modify the property
IF  lr_entity->lock( ) = if_genil_boolean=>true.
  lr_entity->delete( ).
*Modify the Core Object
  lr_core->modify( ).
ENDIF.
* Then Again Use save and commit using transaction contexxt.

      Hi Sumeet,

      do you know the BOL programming how to guide available in the service market place or here: http://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/library/uuid/e0ddd4e6-32f9-2c10-9d88-d993c4b0008d?

      It contains exactly the information you posted here. Only with additional explanations and further examples.

      Hi Christian ,

      I was not aware of this doc...

      I am trying to put as many as sample codes in a single blog and more code samples yet to upload related to navigations pop ups dropdows on click actions etc.....so that if required it can be used by all.

      if there is still any issue related to posing this doc , let me know so that i will delete

      Hi Sumeet,

      i think the examples related to pop ups and drop downs could be interesting.

      With respect to the BOL examples I think you should link to the BOL How To Guide as it is IMHO a very good and complete document.

      Best,

      Hello, Sumeet.

      Thank you for bringing my attention to this post.

      In case of any doubts how to classify this or that content on SCN I personally always refer to The Difference between a Discussion, Blog Post, Document and Wiki document.

      To my mind this particular content had to be put as a Wiki. Or at least a document. Because a blog is intended to express your own opinion or experience.

      I think it's too late to convert to either a wiki or a document now. Quite many people have already bookmarked, rated or liked it. Could you please put at least a reference to the BOL programming guide mentioned by Christian Drumm in your blog post itself? And please use a mentioned post to classify your content in the future. Thank you.

      Hi Sumeet,

      Nice post. I have a dew question about updating a bol layer. I already get a bol header from search method. But it seems doesn't work when I updating the bol layer, after I debug it, the entity is not changeable. I already used the display mode support and switch to change mode. I copied your code in my work, but it still doesn't change to change mode. Does you have some advise about this case?

      Thanks for your share in this blog. It's very helpful.

      Hi Alexander,

      If your header entity is locked, then it wont switch to change mode or in a changeable mode.

      Check the entity might have been locked (already in edit mode) from the front end or gui transaction.

      Sumeet

      Hi Sumeet,

      Thanks for your reply. So, that's mean I can change it directly, since it already in edit mode? or I set it to display mode and then start to lock it again to change the properties values?

      Regards.

      Hi,

      once entity is locked from front end u will be not able to change by code also, try setting it to display mode and then start to lock it again to change the properties values...

      Dear Sumeet,

      How to check for error messages during upload of business partner using BOL.

      Thanks & Regards,

      Hi Rohan,

      you can get the messages from the message container. I'm currently unsure if the BP messages end up in the global message container (via bol_core->get_global_message_cont( )) or in the message container of the entity (

      bol_core->get_message_cont_manager( )->get_message_cont()). In one of those message containers you should be able to read the error messages.

      The following document describes the different message handling approaches in more detail: http://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/library/uuid/f08a833a-f5c0-2e10-bf94-d464bf5355dc?overridelayout=t…

      Dear Christian,

      I have already tried this but I am not able to get messages from lr_core->get_global_message_cont->if_genil_message_container~get_messages

      or lr_core->get_message_cont_manager->get_message_cont->get_messages

      We have to modify the core then get messages from lr_entity->get_message_container to get error messages.

      Thanks & Regards,

      Rohan

      Dear Christian,

      Due to this my number range skips if there exists any error and if I roll backed the transaction.

      Is there exist any other solution.

      Thanks Regards,

      Rohan

      Christian Drumm

      Hi Rohan,

      what do you mean with "my number range skips?".

      Whenever a number is requested from a number range object the number range is increased. For example, if you try to create a BP a new BP number is requested from the number range object. If an error occurs the transaction is rolled back an the BP is not created. If you try to create a new BP again the next number from the number range is requested. The number used in the failed transaction is "lost" and won't be reused.

      If this is the problem you are talking about, there is no solution for it. It is the core functionality of the number range objects that can't be changed.

      Dear Christian,

      You are right but there should be some method to check data before requesting number from number range object.

      I have used BOL it is quiet simple and requires less coding but I am not able to figure out how errors are calculated. Number is requested when I write below statement:

      lr_entity = lr_factory->create( lt_params )

      I have got errors only after below code:

      lr_core->modify( )

      lr_msg_cont = lr_entity->get_message_container( ) "Root Entity

      Using this method if central data contains error number always goes for nothing.

      I tried using BAPI also it requires some extra efforts in coding but atleast checks for errors and if central data contains error it does not generate a number.

      Thanks & Regards,

      Rohan

      Hi Sumeet,

      Having experience with BOL programming already, but 2 years ago, I had to jump into it again, with no time for nice and easy recap (as usually). Your blog, however, contained just about everything one needs for such a lightning fast (re)start.

      Thanks for this!

      Firstly thanks for sharing a nice document.. it is very helpful to create business transaction using BOL Proramming.

      I have followed this document. When i am modifying our transaction i am getting interface changed at runtime.

      While run this line lr_core->modify( ) then i am getting dump.

      Can you please help me out to this issue.

      Regards,

      Puneet Mittal

      Can we add attribute name 'CHANGED_AT' in search query?
