CRM Debugging and BOL Programming to read & populate values

This article talks about CRM Debugging and BOL Programming and how you could navigate the entity structure in CRM to read and update values.

This article is a follow up article from the 1^st one in CRM Debugging and BOL Programming. Please refer to the last article if you haven’t already for CRM Debugging and BOL Programming.

Requirement: To disable one specific field in an Address section
Then find the UI component
Find technical object to do code changes
Get value using IF_BOL_BO_PROPERTY_ACCESS
1. Debug to find where the value is coming from
Then simply get value of UI field using me-> context type
1. Debug to find how this gets populated.

Requirement: Disable a specific UI element field on CRM Debugging and BOL Programming

For customer overview screen when user clicks on edit to update the address information

Disable a specific field called “Delivery service type” and then do not allow to update Phone and email sections as highlighted below.

CRM Debugging and BOL Programming to read & populate values

Find the UI component

UI component was BP_ADDR

And then View value as BP_ADDR/AccountAddressEF

Find Technical object to do code changes on CRM Debugging and BOL Programming

Use transaction obsp_wd_cmpwb to be able to open the component in backend CRM system

Specific fields can be found in

Context_Nodes > Implementation class > Attributes >STRUCT.FIELDNAME

CRM Debugging and BOL Programming to read & populate values

There are different methods that you can find in the context node attributes as was also answered in the post below

GET_XYZ – This is used to get the data of attribute(XYZ) from the BOL Layer and then display it on the UI
SET_XYZ – This is used to set the data of the attribute from the UI to the BOL layer
GET_M_XYZ – This defines the meta data (type) of the attribute
GET_I_XYZ – This defines whether the attibute is editable or non editable i.e, using Get_I method you can make your field as grade out based up on any condition.
GET_V_XYZ – This defines the content of drop down values, F4 Help etc i.e,you can retrieve the dropdown values based up on your condition.
GET_P_XYZ – This defines the property of attribute whether it’s drop down, text box, F4 help, check box etc. Also, if any followup event should trigger the same is mentioned here i.e,you can call specific even handler using P method .
There are two more methods which have recently got added from the above two as mentioned below
GET_A_XYZ – This is used to hide or display the attribute based on the Switch ID.
GET_AC_XYZ – Then this is used for Field Action Menu Getter
Since I need to make the field disabled, I need to make use of the field value GET_M_DELI_SERV_TYPE
You can find this method in context node Buildaddress> Attributes> STRUCT.DELI_SERV_TYPE which has a set of predefined methods as seen below
Then the code which was used to set the value as disabled would be GET_I_XYZ

If the icon does not look green as in the above screenshot choose to redefine or one of then options below to activate the method

Find the source code as below:

  METHOD get_i_deli_serv_type.
    CALL METHOD super->get_i_deli_serv_type
      EXPORTING
        iterator    = iterator
      RECEIVING
        rv_disabled = rv_disabled.

    IF zl_bp_addr_accountaddress_impl=>gv_addr_disabled IS NOT INITIAL.
      rv_disabled = zl_bp_addr_accountaddress_impl=>gv_addr_disabled.
    ENDIF.

ENDMETHOD.

Get value of UI field using IF_BOL_BO_PROPERTY_ACCESS

To access a specific value coming from the previous or current screen then use the BOL property access type as mentioned below where you want to read the value from

In my case I am using ZGO_BOL_PROPERTY defined in class ZL_BP_ADDR_ACCOUNTCOMMNUM_IMPL where I want to read the attribute address number and address GUID which are attributes in that class.

If you check the interface IF_BOL_BO_PROPERTY_ACCESS, it has properties as below:

Additionally, To be able to use the value stored in the property below code needs to be run

In ZL_BP_ADDR_ACCOUNTEMAILSE_IMPL DO_PREPARE_OUTPUT

    DATA: lo_bo        TYPE REF TO  cl_crm_bol_entity,
          lv_addr      TYPE ad_addrnum,
          lv_addr_guid TYPE bu_address_guid.

   IF zl_bp_addr_accountcommnum_impl=>zgo_bol_property IS NOT INITIAL .
      lo_bo ?=  zl_bp_addr_accountcommnum_impl=>zgo_bol_property.
    ENDIF.

    IF lo_bo IS BOUND .
      lo_bo->get_property_as_value(
        EXPORTING
          iv_attr_name =     ‘ADDRESS_NUMBER’
        IMPORTING
          ev_result    =       lv_addr
      ).

      lo_bo->get_property_as_value(
  EXPORTING
    iv_attr_name =     ‘ADDRESS_GUID’
  IMPORTING
    ev_result    =       lv_addr_guid
).

ENDIF .

Check in debug mode where the value is coming from

For the implementation class then you can use ZL_BP_ADDR_ACCOUNTCOMMNUM_IMPL=>ZGO_BOL_PROPERTY

Go to container_proxy
Then Go to Data_Ref
And then Click on data type which opens up
Open the attribute_ref
Then simply Find the address number and address value in there

Find the container proxy

1:Click on Data_ref

2:Then Click on the type below

3:Click on Attribute ref

Then find the values

Get value of UI field using me-> context type

The code using me-> would be calling the context field

ZTYPED_CONTEXT needs to be defined of type ZL_BP_ADDR_ACCOUNTCOMMNUM_CTXT

In the implementation method ZL_BP_ADDR_ACCOUNTCOMMNUM_IMPL

In this case since we have defined a parameter using the context interface as below

DATA: lo_bo        TYPE REF TO  cl_crm_bol_entity,
lv_addr      TYPE ad_addrnum,
lv_addr_guid TYPE bu_address_guid.
lo_bo ?= me->ztyped_context->builaddress->collection_wrapper->find(
iv_index  = cl_bp_addr_corpaccountad1_impl=>gv_index

Check in debug mode what value is being sent on CRM Debugging and BOL Programming

ztyped_context->builaddress->collection_wrapper->

Moreover, Insider collection wrapper you would find collection reference

Insider collection reference look for

Additionally, Look for entity list as above which shows 3 entries as there are 3 BP addresses on the UI

Further, go to one of the entities and it would have container proxy

Therefore follow the same steps as in 4.1

Go to container_proxy
Then Go to Data_Ref
And then Click on data type which opens up
After that Open the attribute_ref
Then simply Find the address number and address value in there. For more services and information:https://peritossolutions.com/newdev.peritossolutions.com/services/sap-consulting-services
