[Event Request][W1][Page][6532][Continuous Item Tracking] Add OnBeforeValidateInput to LastInput OnValidate

[GonzaloGuerraVicente]

Why do you need this change?

I want to be able to parse the data readed from a GS1-128 Barcode to extract the Application Identifiers needed.
For example, for the following barcode I need to extract the AI "10" witch corresponds to the Lot Number.

Describe the request

A possible Event Publisher would look like

field("Scanning Area"; LastInput)
{
	Caption = 'Input';
	Editable = true;
	Lookup = true;
	ToolTip = 'Specifies the content scanned to input.';

	trigger OnValidate()
	begin
		OnBeforeValidateInput(LastInput, SourceItemTrackingEntryType);
		if ContinuousScanningMode then
			CurrPage.Close();
	end;
}

[IntegrationEvent(false, false)]
local procedure OnBeforeValidateInput(var Input: Text; ItemTrackingEntryType: Enum "Item Tracking Entry Type")
begin
end;

Internal work item: AB#617041

Implementation:

Add a new integration event in the OnValidate() trigger of the "Scanning Area" field in Page 6532 "Continuous Item Tracking" before the existing logic.

Location in OnValidate() trigger (around line 29):

trigger OnValidate()
begin
    OnBeforeValidateInput(LastInput, SourceItemTrackingEntryType);
    if ContinuousScanningMode then
        CurrPage.Close();
end;

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

[IntegrationEvent(false, false)]
local procedure OnBeforeValidateInput(var Input: Text; ItemTrackingEntryType: Enum "Item Tracking Entry Type")
begin
end;
