Use this event to
Create new DataTables ("ListData") that can be used from Steps and HeaderConfigurations.
DataTables are static data in Reference Data, meaning they are loaded on login and cannot change dynamically.
Description
A DataTable is a lists of "entries" sharing a common DataTableId, usually used to fill choices in dropdown-lists at the Mobile Device. DataTables can be referenced from Steps or HeaderConfigurations.

DataTable or listValues?
An alternative to DataTables is listValues that has advantages and disadvantages as compared to DataTables:
DataTable | listValues |
---|---|
Static, loaded only once at login | Can be dynamic, is created at time of XmlResponse |
Can be reused, is referenced only by its key (DataTableId) | Lists must be created and sent with XmlResponse |
Most efficient, is created and loaded only once at login | Less efficient, in particular if lists are large |
Can contain multiple fields per entry ie. Code and Name | Contains only one field per entry |
Requires this addtional eventsubscriber to create the DataTable | Requires no extra eventSubscriber to create the listValues |
Consider using Steps.Create_ListStepFromListValues()
or HeaderField.Create_ListFieldFromListValues()
if your lists are short, needs to be dynamic - and do not require multiple fields per entry.
Template

procedure OnGetReferenceData_OnAddDataTables(var _DataTable: Record "MOB DataTable Element")
begin

InitDataTable('MyCustomDataTableId'); // Replace with your own dataTable identifier to be used with Set_dataTable(...) from Steps and HeaderConfigurations
// Create your DataTable entries here

Example (1)
// [Example] 01 - Create new custom DataTable based on BC table using a Create_XXX template
[EventSubscriber(ObjectType::Codeunit, Codeunit::"MOB WMS Reference Data", 'OnGetReferenceData_OnAddDataTables', '', true, true)]

InitDataTable('MyCountries');
if CountryRegion.FindFirst() then
repeat
Create_CodeAndName(CountryRegion.Code, CountryRegion.Name);
until CountryRegion.Next() = 0;
end;
end;
Example (2)
// [Example] 02 - Create new custom DataTable based on with no use of templates
[EventSubscriber(ObjectType::Codeunit, Codeunit::"MOB WMS Reference Data", 'OnGetReferenceData_OnAddDataTables', '', true, true)]
procedure My02OnGetReferenceData_OnAddDataTables(var _DataTable: Record "MOB DataTable Element")

SetValue('Code', CountryRegion.Code);
SetValue('ISOCode', CountryRegion."ISO Code");
SetValue('EUCode', CountryRegion."EU Country/Region Code");
until CountryRegion.Next() = 0;
