D365FFO: System.InvalidOperationException. Only properties of simple type can be key properties.

Actually there is a Know BUG if you use ODATA references from NUGET.


If a data entity has an enum type field on the entity primary key, the system will report this error:


An unhandled exception of type ' System.InvalidOperationException' occurred in Microsoft.OData.Client.dll
Additional information: The key property 'Type' on for type
'ProductsApp4.Microsoft.Dynamics.DataEntities.LegalEntityContact' is of
type 'System.Nullable`1[[ProductsApp4.Microsoft.Dynamics.DataEntities.LogisticsElectronicAddressMethodType, ProductsApp4, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null]]', which is not a simple type. Only properties of simple type can be key properties.


To resolve the issue, remove NUGET references from the project and use this custom OData dlls: in https://github.com/Microsoft/Dynamics-AX-Integration/tree/master/Packages



Pay attention if you are installing client on OS is Win7 x64 or Vista x64 and you got an error something like that:


{"Could not load file or assembly 'TheAssemblyYouHaveReferenced' or one of its dependencies. Strong name validation failed. (Exception from HRESULT: 0x8013141A)":"TheAssemblyYouHaveReferenced'}

D365FFO: Importing customers using data entity does not init value from customer group

Importing customers using dataentity does not init data from customer group, for example Payment Terms does not automatically inizialized from group.

This extension on CustCustomerEntity data entity will fix that problem

[ExtensionOf(dataentityviewstr(CustCustomerEntity))]
final class CustCustomerEntity_Extension
{
    [DataEventHandler(tableStr(CustCustomerEntity), DataEventType::MappedEntityToDataSource)]
    public static void CustCustomerEntity_onMappedEntityToDataSource(Common _sender, DataEventArgs _eventArgs)
    {
        CustCustomerEntity custCustomerEntity = _sender;
        DataEntityContextEventArgs dataEntityContextEventArgs = _eventArgs;

        DataEntityDataSourceRuntimeContext _dataSourceCtx = dataEntityContextEventArgs.parmEntityDataSourceContext();
        if (_dataSourceCtx.name() == dataEntityDataSourceStr(CustCustomerEntity, CustTable))
        {
            CustTable custTable = _dataSourceCtx.getBuffer();
            custTable.initFromCustGroup(CustGroup::find(custTable.CustGroup));
        }
    }
}
