Dynamic mandatory field or force refresh view

[former_member774423]

Hello.
I am trying to make a field mandatory depending on the status of an object. I do it through "external_calculation".

View Code:

@AbapCatalog.sqlViewName: 'ZIDVAGOODSRECSTP'
@AbapCatalog.compiler.compareFilter: true
@AbapCatalog.preserveKey: true
@AccessControl.authorizationCheck: #CHECK
@EndUserText.label: 'Goods Records View'

@VDM.viewType: #TRANSACTIONAL

@ObjectModel.modelCategory: #BUSINESS_OBJECT
@ObjectModel.compositionRoot: true
@ObjectModel.transactionalProcessingEnabled: true
@ObjectModel.writeActivePersistence:'ZTDVA_GOODS'
@ObjectModel.createEnabled: true
@ObjectModel.deleteEnabled: true
@ObjectModel.updateEnabled: true
@ObjectModel.draftEnabled: true
@ObjectModel.writeDraftPersistence: 'ZTDVA_GOODS_D'
@ObjectModel.semanticKey: ['GoodUuid', 'StoreUuid']

define view ZI_DVA_GoodsRecordsTP 
as select from ZI_DVA_Goods 
{   
    @ObjectModel.readOnly: true
    key GoodUuid,
    @ObjectModel.mandatory: true
    StoreUuid,
    @ObjectModel.mandatory: true
    Name,
    @ObjectModel.mandatory: 'EXTERNAL_CALCULATION'
    Quantity,
    @Semantics.amount.currencyCode : 'Currency'
    @ObjectModel.mandatory: true
    Price,
    @Semantics.currencyCode: true
    @ObjectModel.mandatory: true
    Currency,
    @ObjectModel.mandatory: true
    StatusUuid,
    
    _Statuses.Status,
    _Stores.Name as StoreName,

    _Statuses,
    _Stores,
    _GoodsLogs
}

Code in determination:

method /BOBF/IF_FRW_DETERMINATION~EXECUTE.

    DATA lt_goods TYPE ztidva_goodsrecordstp.

    io_read->retrieve(
    EXPORTING
        iv_node = is_ctx-node_key
        it_key  = it_key
    IMPORTING
        et_data = lt_goods ).

    data(lo_property_helper) = new /bobf/cl_lib_h_set_property( io_modify = io_modify
                                                    is_context = is_ctx ).

    LOOP AT lt_goods INTO DATA(ls_good).

        IF ls_good-StatusUuid = 'mS{Jam7V7ko6s72CWlRP{W'.
            lo_property_helper->set_attribute_mandatory(
                iv_attribute_name = zif_i_dva_goodsrecordstp_c=>sc_node_attribute-zi_dva_goodsrecordstp-quantity
                iv_value          = abap_true
                iv_key            = ls_good-key ).
        ELSE.
            lo_property_helper->set_attribute_mandatory(
                iv_attribute_name = zif_i_dva_goodsrecordstp_c=>sc_node_attribute-zi_dva_goodsrecordstp-quantity
                iv_value          = abap_false
                iv_key            = ls_good-key ).
        ENDIF.

    ENDLOOP.
  endmethod.

This way works. Only if you change the status and refresh the page or click on the save button, the action of which updates the view. How do I make the view change without refreshing the page or how do I refresh the view?

probably the side effects are missing.

Hi Mahesh,

Is this available only for RAP? Does ABAP Programming model also has this feature?

I couldn't find 'Side effect' from annotation

Thanks
