Description

Use case

This example shows you how to transfer values from an Order Line to a new unplanned function.

Calculating the remaining quanity of the line and presenting this to the user, for them to change.

Note: The example has no logic to save the collected quanity in the database

This example gives you

• An new Unplanned function as action in Pick Lines
• Three
  That transfers Location, Bin and Item from the Order lines
• One decimal step to collect a value from the user 

The unplanned workflow

Make sure the unplanned workflow suits your requirement.

• See Unplanned Functions

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 to determine which Steps to collect.

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

OnGetReferenceData_OnAddHeaderConfigurations

 [EventSubscriber(ObjectType::Codeunit, Codeunit::"MOB WMS Reference Data", 'OnGetReferenceData_OnAddHeaderConfigurations', '', true, true)]
    localprocedure 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".

    begin
        _HeaderFields.InitConfigurationKey('MyHeader'); // Identifier for new Header - replace by your own name        // Add Header fields here
        _HeaderFields.Create_DateField(10, 'MyDate', 'Select date');
        _HeaderFields.Create_TextField(20, 'MyText', 'Enter text');
        _HeaderFields.Set_optional(true);
        _HeaderFields.Create_DecimalField(30, 'MyDecimal', 'Enter decimal');
    end;

Step 3: Return Steps to collect ^(Optional)

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

In this step you must read the values header fields and define the subsequent steps.

If you want to collect steps you must set useRegistrationCollector="true" in Mobile Configuration Files.

<page>
  <unplannedItemRegistrationConfiguration type="MyUnplanned" useRegistrationCollector="true"> 
<..>

You can use the already collected header fields values for:

        MyDecimal: Decimal;
    begin
        // Handle only your own Header name
        if _RegistrationType <> 'MyUnplanned' then
            exit;

Step 4: Handle posting

When the Header has been accepted and Steps collected, a final request is made to "Post" the information ("PostAdhocRegistration")

In this step you must read the collected values and post them to the database.

Step 5: Set tracking info (optional)

The parameter _RegistrationTypeTracking can be used to make the Document Queue display additional information about your process.
