Description

The API event parameters does not include all the information you want

Use case

In this example we will use a work-around read the current mobile request

Step 1: Adding custom header filter

Using OnGetReferenceData_OnAddHeaderConfigurations a Header Field called MyFilter is added

[EventSubscriber(ObjectType::Codeunit, Codeunit::"MOB WMS Reference Data", 'OnGetReferenceData_OnAddHeaderConfigurations', '', true, true)]
local procedure GetReferenceData_OnAddHeaderConfigurations(var _HeaderFields: Record "MOB HeaderField Element")
begin
// Header keys can be found by inspecting the GetReferenceData response that happens with every mobile login
_HeaderFields.InitConfigurationKey('PickOrderFilters');
_HeaderFields.Create_TextField(15, 'MyFilter', 'My filter:');
end;

Step 2: Reading the filter from event

The event OnGetPickOrders_OnIncludeWarehouseActivityHeader does not includs header-filters.

Using the Document Queue we retrieve the entire current XML Request
Now we can use the familiar "GetValue"-function to retrieve the MyFilter filter-value

[EventSubscriber(ObjectType::Codeunit, Codeunit::"MOB WMS Pick", 'OnGetPickOrders_OnIncludeWarehouseActivityHeader', '', true, true)]

local procedure OnGetPickOrders_OnIncludeWarehouseActivityHeader(_WhseActHeader: Record "Warehouse Activity Header"; var _IncludeInOrderList: Boolean)
var
MobDocQueue: Record "MOB Document Queue";
TempHeaderFilter: Record "MOB NS Request Element" temporary;
MobSessionData: Codeunit "MOB SessionData";
MobRequestMgt: Codeunit "MOB NS Request Management";
XMLRequestDoc: XmlDocument;
begin
MobDocQueue.GetByGuid(MobSessionData.GetPostingMessageId(), MobDocQueue);
MobDocQueue.LoadXMLRequestDoc(XMLRequestDoc);
MobRequestMgt.SaveHeaderFilters(XmlRequestDoc, TempHeaderFilter);

error('%1', TempHeaderFilter.GetValue('MyFilter')); // This will display "MyFilter" on mobile device
end;
