Description

Add a new Unplanned Function as action on Pick Lines.

Use case

This example shows transfers values from an Order Line to a new unplanned function.

This example results in

One new Unplanned Functions
- One action on "Pick Lines" to this function
Three Header-fields
- That transfers Location, Bin and Item from the Order line
A step to collect a decimal value from the user

Using the transferred values when adding the step

We use the transferred values when adding the decimal step:

The registered (not yet posted) quantity is compared to the full line quantity
The result is suggested as Default Value in the step

Step 1: Defining a new Unplanned function

This part requires you to edit the Mobile Configuration Files

Add this section in the <pages> tag.

<!-- Custom -->
<page id="UnableToPick" type="UnplannedItemRegistration" icon="mainmenunegativeadjustment">
    <title defaultValue="Unable To Pick"/>
    <unplannedItemRegistrationConfiguration type="UnableToPick">
    <header configurationKey="UnableToPick" automaticAcceptOnOpen="true"/>
  </unplannedItemRegistrationConfiguration>
</page>
<!-- Custom -->

We want to add this to the existing Pick Lines page in the Action Menus Then add this section to the <actions> tag of Pick Lines page:

<page id=Picklines...>
<...>
<actions>
  <!-- Custom --> 
    <open id="UnableToPick" icon="mainmenunegativeadjustment" title="Unable To Pick"/>
  <!-- Custom -->

Step 2: Define Header and header fields

Unplanned functions uses Header-fieldsto determine which Steps to collect.

In this step you must define which header fields you want the user to see.

[EventSubscriber(ObjectType::Codeunit, Codeunit::"MOB WMS Reference Data", 'OnGetReferenceData_OnAddHeaderConfigurations', '', true, true)]
local procedure MynGetReferenceData_OnAddHeaderConfigurations(var _HeaderFields: Record "MOB HeaderField Element")
begin
_HeaderFields.InitConfigurationKey('UnableToPick'); // Name of Header

// Add Header fields
// Using pre-defined helper-functions makes it easy to transfer values as field names match 100%
_HeaderFields.Create_ListField_Location(10); // 'Location' is a known field on OrderLines response
_HeaderFields.Set_locked(true);

_HeaderFields.Create_TextField_FromBin(20); // 'FromBin' is a known field on OrderLines response
_HeaderFields.Set_locked(true);

_HeaderFields.Create_TextField_ItemNumber(30); // 'ItemNumber' is a known field on OrderLines response
_HeaderFields.Set_locked(true);
end;

Step 3: Return Steps to collect

When the header is accepted a new request is made for which Steps to collect, called "GetRegistrationConfiguration".

[EventSubscriber(ObjectType::Codeunit, Codeunit::"MOB WMS Adhoc Registr.", 'OnGetRegistrationConfiguration_OnAddSteps', '', true, true)]
local procedure CollectFailedQty(_RegistrationType: Text; var _HeaderFieldValues: Record "MOB NS Request Element"; var _Steps: Record "MOB Steps Element"; var _RegistrationTypeTracking: Text)
var
MobToolbox: Codeunit "MOB Toolbox";
UnableToPickQuantity: Decimal;
begin
// Handle only this type
if _RegistrationType <> 'UnableToPick' then
exit;

// Reading Header values (not needed in this example)
// _HeaderFieldValues.Get_Location(); // Helper functions exists for common names
// _HeaderFieldValues.GetValue('AnyField'); // Any custom name
// _HeaderFieldValues.GetValueAsDecimal('AnyField'); // Get a value as decimal

// Reading context values inherited from Order Lines

// Calculate suggested quantity that was unable to be picked
UnableToPickQuantity := _HeaderFieldValues.GetContextValueAsDecimal('Quantity') - // The remaining quantity to be picked
_HeaderFieldValues.GetContextValueAsDecimal('RegisteredQuantity'); // Subtract the currently registered quantity, not-yet-posted (if any)

// Create "Decimal Step" to collect the failed quantity
_Steps.Create_DecimalStep(10, 'UnableToPickQuantity', false);
_Steps.Set_header('Unable to pick');
_Steps.Set_label('Quantity:');
_Steps.Set_helpLabel('Please input the quantity you were unable to pick');

_Steps.Set_defaultValue(UnableToPickQuantity); // Suggest our calculated value as DefaultValue
_Steps.Set_minValue(0.0000000001); // Must be a positive number
_Steps.Set_eanAi(MobToolbox.GetQuantityGS1Ai()); // Set AI to quantity (310,30,37) so GS1 barcodes scans directly into the step

// (Create more steps here)
end;

If you fail to perform this step, you will receive this error.

Step 4: Handle posting

You can now run your function from Mobile.

Steps has been collected and you press "Accept". Now request is made to "Post" the information ("PostAdhocRegistration")
In this step you must read the collected values and post them to the database
- See View Request and Response XML and Error Call Stack

XML Example of the Post Request

<?xml version="1.0" encoding="utf-8"?>
<request name="PostAdhocRegistration" created="2020-02-14T15:24:24+01:00" xmlns="http://schemas.microsoft.com/Dynamics/Mobile/2007/04/Documents/Request">
  <requestData name="PostAdhocRegistration">
    <MyDate>14-02-2020</MyDate>
    <MyText>2</MyText>
    <MyDecimal>4</MyDecimal>
    <MyDateStep>14-02-2020</MyDateStep>
    <MyTextStep>2</MyTextStep>
    <MyDecimalStep>4</MyDecimalStep>
    <RegistrationType>MyUnplanned</RegistrationType>
  </requestData>
</request>

Note how both Header values and Steps values are available. in the XML.

The values are extracted from the _RequestValues parameter using "GetValue "functions.

[EventSubscriber(ObjectType::Codeunit, Codeunit::"MOB WMS Adhoc Registr.", 'OnPostAdhocRegistrationOnCustomRegistrationType', '', true, true)]
local procedure MyOnPostAdhocRegistrationOnCustomRegistrationType(_RegistrationType: Text; var _RequestValues: Record "MOB NS Request Element"; var _CurrentRegistrations: Record "MOB WMS Registration";
var _SuccessMessage: Text; var _RegistrationTypeTracking: Text; var _IsHandled: Boolean)
begin
// Handle only this type
if _RegistrationType <> 'UnableToPick' then
exit;

if _IsHandled then
exit;

// << Perform your own logic here >>

// To illustrate the values are collected in this example, the values are used in the success-message and thus displayed to the user
_SuccessMessage := StrSubstNo('Document %1 Line %2 failed to pick %3', // Display the collected values
_RequestValues.GetValueOrContextValue('OrderBackendId'), // Order Mo.
_RequestValues.GetValueOrContextValue('LineNumber'), // LineNumber
_RequestValues.GetValueAsDecimal('UnableToPickQuantity')); // The collected value

_RegistrationTypeTracking := 'Tracking info for the Document queue.';
_IsHandled := true;
end;
