How to write the standard data entity extension method

-

 Today we have a requirement to call the modified and other method of the standard data entity while we are going to import So below are the example 


[ExtensionOf(dataentityviewstr(EntAssetMaintenanceWorkOrderTableEntity))]

internal final class IHSEntAssetMaintenanceWorkOrderTableEntity_Extension

{

    



    public void mapEntityToDataSource(DataEntityRuntimeContext _entityCtx, DataEntityDataSourceRuntimeContext _dataSourceCtx)

    {

        next mapEntityToDataSource(_entityCtx, _dataSourceCtx);


        switch (_dataSourceCtx.name())

        {

            case dataEntityDataSourceStr(EntAssetMaintenanceWorkOrderTableEntity,ENtAssetWorkorderTable):

                if(this.FromFunctionalLocationId)

                {

                    InventLocation warehouse;

                    ENtAssetWorkorderTable request             = _entityCtx.getRuntimeContextByName(dataEntityDataSourceStr(EntAssetMaintenanceWorkOrderTableEntity, ENtAssetWorkorderTable)).getBuffer();

                    EntAssetFunctionalLocation fromFunctionalLocation = EntAssetFunctionalLocation::find(this.FromFunctionalLocationId);


                    request.FromSite = fromFunctionalLocation.InventSiteId;

                    request.FromLocationId = fromFunctionalLocation.InventLocationId;

                    warehouse                              = InventLocation::find(fromFunctionalLocation.InventLocationId);

                    request.FromwMSLocationId              = warehouse.WMSLocationIdDefaultReceipt;

                }

                if(this.ToFunctionalLocationId)

                {

                    InventLocation warehouse;

                    ENtAssetWorkorderTable request             = _entityCtx.getRuntimeContextByName(dataEntityDataSourceStr(EntAssetMaintenanceWorkOrderTableEntity, ENtAssetWorkorderTable)).getBuffer();

                    EntAssetFunctionalLocation ToFunctionalLocation = EntAssetFunctionalLocation::find(this.ToFunctionalLocationId);


                    request.ToSite = ToFunctionalLocation.InventSiteId;

                    request.ToLocationId = ToFunctionalLocation.InventLocationId;

                    warehouse                              = InventLocation::find(ToFunctionalLocation.InventLocationId);

                }

                break;
