Description

This information applies to all Planned functions.

There are two methods for filtering orders

1. OnSetFilter: Basic filter  (this article)
   
   • Works with both standard and custom Header-fields
     
     
2. OnInclude: Complex per-document filter
   
   • Used for conditions that cannot be solved by OnSetFilter.
   • Elements cannot be "re-included" once excluded via OnSetFilter-events
   • See How-to: Filter Orders - Complex

How to handle filters

Step 1 - Select the event

Select the correct event for the function area you are working on.

Step 2 - Structure your code

Make sure to affect all related documents if needed

Example: A change in filter "PO Number" should affect both:

• "Warehouse Receipts"
• "Purchase Orders"

Make your code callable from both events:

• OnGetReceiveOrders_OnSetFilterPurchaseOrder

• OnGetReceiveOrders_OnSetFilterWarehouseReceipt

Important note:

• Line filters also affect Orders. If no Lines fits the filter, then the corresponding Order is excluded

Step 3 - Write your code

You are given these parameters to use for your filtering

Examples

Note: The examples use Receive function, but works for all Planned Functions

Example 01: Modify "Location" filter

    [EventSubscriber(ObjectType::Codeunit, Codeunit::"MOB WMS Receive", 'OnGetReceiveOrders_OnSetFilterWarehouseReceipt', '', true, true)]
        local procedure Example01_Additional_Location_Filtering(_HeaderFilter: Record "MOB NS Request Element"; var _WhseReceiptHeader: Record "Warehouse Receipt Header"; var _WhseReceiptLine: Record "Warehouse Receipt Line"; var _IsHandled: Boolean)
    begin
        // [Scenario]
        // Modify "Location" filter
        // Only if location is = "WHITE" OR "GREEN". Set filter to include Both Location, no matter which is chosen
        // Handle the filter, so standard filter is overruled

        if _HeaderFilter.Name = 'Location' then
            if _HeaderFilter."Value" IN ['WHITE', 'GREEN'] then begin
                _WhseReceiptHeader.SetFilter("Location Code", '%1|%2', 'WHITE', 'GREEN');
                _IsHandled := true;
            end;

        // When Filter is NOT "White" or "Green", the standard code runs as normal and filters on the choosen location
    end;

Example 02: Modify "Expected Receipt Date" filter

    [EventSubscriber(ObjectType::Codeunit, Codeunit::"MOB WMS Receive", 'OnGetReceiveOrders_OnSetFilterWarehouseReceipt', '', true, true)]
    local procedure Example02_Overrule_ExptRecptDate_Filter(_HeaderFilter: Record "MOB NS Request Element"; var _WhseReceiptHeader: Record "Warehouse Receipt Header"; var _WhseReceiptLine: Record "Warehouse Receipt Line"; var _IsHandled: Boolean)
    begin
        // [Scenario]
        // Add additional Receipt lines are default filtered for "Due Date" filter to the standard using the formula <=%1 where %1 is "Expected Receipt Date" filter on Receipt Lines
        // Note: A filter
        // Overrule the filter to always search one year from the current workdate
        // Filter on LINES will also affect which Orders are included
        // Handle the filter, so standard filter is overruledORDERS that are included

        if _HeaderFilter.Name = 'Date' then begin

            _WhseReceiptLine.SetFilter("Due Date", '..%1', CalcDate('<CY+1Y>', WorkDate()));  // One year from the current workdate
            _IsHandled := true;
        end;
    end;

Example 03: Modify "Purchase Order" filter

   [EventSubscriber(ObjectType::Codeunit, Codeunit::"MOB WMS Receive", 'OnGetReceiveOrders_OnSetFilterWarehouseReceipt', '', true, true)]
       local procedure Example03_Validate_PurchaseOrder_Filter(_HeaderFilter: Record "MOB NS Request Element"; var _WhseReceiptHeader: Record "Warehouse Receipt Header"; var _WhseReceiptLine: Record "Warehouse Receipt Line"; var _IsHandled: Boolean)
    var
        PurchaseHeader: Record "Purchase Header";
    begin
        // [Scenario]
        // Add validation to the "Purchase Order" filter by checking the order is Open
        // If not, abort process and force user to change filter

        if _HeaderFilter.Name = 'PurchaseOrderNumber' then
            if PurchaseHeader.Get(PurchaseHeader."Document Type"::"Order", _HeaderFilter."Value") and (PurchaseHeader.Status <> PurchaseHeader.Status::Released) then
                Error('Purchase Order %1 is not released', PurchaseHeader."No."); // We use "error" since filter a single document no. (Error is not recommended for common filtering)

        // _IsHandled: No point in handling the filter or not, as Error stops the entire proces if needed
    end;

Example 04: Modify "Assigned User" filter

    [EventSubscriber(ObjectType::Codeunit, Codeunit::"MOB WMS Receive", 'OnGetReceiveOrders_OnSetFilterWarehouseReceipt', '', true, true)]
    procedure Example04_Overrule_AssignedUserAll_Filter(_HeaderFilter: Record "MOB NS Request Element"; var _WhseReceiptHeader: Record "Warehouse Receipt Header"; var _WhseReceiptLine: Record "Warehouse Receipt Line"; var _IsHandled: Boolean)
    local begin
        // [Scenario]
        // Overrule when the standard filter "Assigned User" is set to "All"
        // Instead of no filter, set a filter that must not be Blank
        // Handle the filter, so standard filter is overruled

        if _HeaderFilter.Name = 'AssignedUser' then
            if _HeaderFilter."Value" = 'All' then begin
                _WhseReceiptHeader.SetFilter("Assigned User ID", '<>%1', '');  // Order must be assigned to someone
                _IsHandled := true;
            end;
    end;

Example 05: Modify "ScannedValue" filter

If you are scanning an Encoded Barcode (GS1) then you have to update the"orderFilterGs1AI" on Planned (Service) Mobile Configuration.

See Select Order by scan (scannedValue) for details.

    [EventSubscriber(ObjectType::Codeunit, Codeunit::"MOB WMS Receive", 'OnGetReceiveOrders_OnSetFilterWarehouseReceipt', '', true, true)]
        local procedure Example05_Validate_ScannedValue_Filter(_HeaderFilter: Record "MOB NS Request Element"; var _WhseReceiptHeader: Record "Warehouse Receipt Header"; var _WhseReceiptLine: Record "Warehouse Receipt Line"; var _IsHandled: Boolean)
    begin
        // [Scenario]
        // Overrule when the standard filter "Scanned Value"
        // Instead of searching for Item No., use the value to filter Document no.
        // Handle the filter, so standard filter is overruled

        if _HeaderFilter.Name = 'ScannedValue' then begin
            _WhseReceiptHeader.SetRange("No.", _HeaderFilter."Value");
            _IsHandled := true;
        end;
    end;
