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

    Requirement: Disable a specific UI element field

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

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


    Find the UI component

    UI component was BP_ADDR

    And View value as BP_ADDR/AccountAddressEF


    Find Technical object to do code changes

    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

    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 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 – 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

    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
            iterator    = iterator
            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.


    Get value of UI field using IF_BOL_BO_PROPERTY_ACCESS

    To access a specific value coming from the previous or current screen 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:

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


        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.

        IF lo_bo IS BOUND .
              iv_attr_name =     ‘ADDRESS_NUMBER’
              ev_result    =       lv_addr

        iv_attr_name =     ‘ADDRESS_GUID’
        ev_result    =       lv_addr_guid

        ENDIF .

    Check in debug mode where the value is coming from

    For the implementation class you can use ZL_BP_ADDR_ACCOUNTCOMMNUM_IMPL=>ZGO_BOL_PROPERTY

    1. Go to container_proxy
    2. Go to Data_Ref
    3. Click on data type which opens up
    4. Open the attribute_ref
    5. Find the address number and address value in there

    Find the container proxy

    Click on Data_ref

    Click on the type below

    Click on Attribute ref

    Find the values

    Get value of UI field using me-> context type

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


     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:


    Insider collection wrapper you would find collection reference

    Insider collection reference look for

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

    Go to one of the entities and it would have container proxy

    Follow the same steps as in 4.1

    1. Go to container_proxy
    2. Go to Data_Ref
    3. Click on data type which opens up
    4. Open the attribute_ref
    5. Find the address number and address value in there
