[Event Request] codeunit 905 "Assembly Line Management" procedure ShowAvailability()

[kmistrytnp]

Why do you need this change?

In certain circumstances I want to be able to either skip showing the availability page when the QtyAvailToLow is true and/or the ShowPageEvenIfEnoughComponentsAvailable is true. In other circumstances I want to show an error when the QtyAvailToLow is true and/or the ShowPageEvenIfEnoughComponentsAvailable is true.

I've tried using the OnBeforeShowAvailability() event at the start but can't achieve what I want because I would need to call the CopyInventoriableItemAsmLines and AvailToPromise procedures in order to calculate QtyAvailTooLow, but they are currently local. I have also tried replicating them but I can't because AvailToPromise calls other procedures which are local.

Describe the request

Please can you add the following event/code after the QtyAvailTooLow boolean field has been set...

OnAfterQtyAvailTooLowCalculated(TempAssemblyHeader, TempAssemblyLine, ShowPageEvenIfEnoughComponentsAvailable, IsHandled, Rollback, WarningModeOff);
if IsHandled then
    exit(Rollback);

The event publisher would be...

[IntegrationEvent(false, false)]
local procedure OnAfterQtyAvailTooLowCalculated(var TempAssemblyHeader: Record "Assembly Header" temporary; var TempAssemblyLine: Record "Assembly Line" temporary; ShowPageEvenIfEnoughComponentsAvailable: Boolean; var IsHandled: Boolean; var RollBack: Boolean; WarningModeOff: Boolean)
begin
end;

Hi @kmistrytnp,

Thank you for your extensibility request. To help us process it efficiently, please update the issue to include the required information.

📚 Extensibility Guidelines

Missing Information:

• Performance considerations: Please describe the expected execution frequency of this new IsHandled event and any anticipated performance impact.
• Data sensitivity review: Please confirm whether this event would expose any sensitive data, or state that no sensitive data exposure is involved.
• Multi-extension interaction: Please acknowledge possible conflicts between multiple subscribers using IsHandled/Rollback, or explain why the risk is low for this scenario.

Please update the issue with the missing details. We'll automatically re-analyze once updated.

Performance considerations:
The event will be called whenever the system needs to check for insufficient stock for assembly orders and before showing the assembly availability page. It is not in a tight loop being called many times and so has very little performance impact if any. Bearing in mind that a page is shown (modally) to the user when stock is low, an additional call to an event will make no different to user performance.

Data sensitivity review:
No sensitive data is exposed, the parameters requested in the new event are exactly the same as the ones in the OnBeforeShowAvailability event at the start of this procedure.

Multi-extension interaction:
There is already an IsHandled event at the start of this procedure so adding a new one has no addtional risk.

Implementation:

Add a new integration event in ShowAvailability() after QtyAvailTooLow is calculated so extensions can override the default flow and exit early with a controlled rollback result.

Location in ShowAvailability() procedure:

        then
            exit(false);

        TempAssemblyHeader.TestField("Item No.");
        CopyInventoriableItemAsmLines(TempAssemblyLine2, TempAssemblyLine);
        AvailToPromise(TempAssemblyHeader, TempAssemblyLine2, QtyAvailToMake, EarliestAvailableDateX);
        QtyAvailTooLow := QtyAvailToMake < TempAssemblyHeader."Remaining Quantity";
        IsHandled := false;
        OnShowAvailabilityOnAfterCalcQtyAvailTooLow(
            TempAssemblyHeader, TempAssemblyLine, ShowPageEvenIfEnoughComponentsAvailable, QtyAvailTooLow, IsHandled, Rollback, WarningModeOff);
        if IsHandled then
            exit(Rollback);

        if QtyAvailTooLow and not ShowPageEvenIfEnoughComponentsAvailable then
            Rollback := CreateAndSendNotification(TempAssemblyHeader, TempAssemblyLine)
        else
            if ShowPageEvenIfEnoughComponentsAvailable then
                ShowAssemblyAvailability(TempAssemblyHeader, TempAssemblyLine2, '');

Event Publisher (add at the end of the codeunit with other events):

    [IntegrationEvent(false, false)]
    local procedure OnShowAvailabilityOnAfterCalcQtyAvailTooLow(var TempAssemblyHeader: Record "Assembly Header" temporary; var TempAssemblyLine: Record "Assembly Line" temporary; ShowPageEvenIfEnoughComponentsAvailable: Boolean; QtyAvailTooLow: Boolean; var IsHandled: Boolean; var Rollback: Boolean; WarningModeOff: Boolean)
    begin
    end;
