Lookup Fields button

The Lookup Fields button is enabled on Spoke to Hub tab only if you have selected the Enable Business Object Lifecycle check box while Creating the Hub entity. Click the Lookup Fields button. The Select lookup fields dialog box appears. Select the fields that uniquely identify the business object. Click Save button to save the changes.
Note: The Lookup Fields button is enabled on Spoke to Hub tab only if the Hub entity has State Engine enabled. Do not include any auto-incremental field. Auto incremental fields are those fields whose value increases automatically for every new entry that is added. For example, if the employee ID of the last person recruited by a company is EMP598, and if the employee ID of the next new recruit will automatically be EMP599, then employee ID is an auto-incremental field.

Select a Data Transformation

Select a data transformation using (Select a Data Transformation). Select a data transformation when you have to map the data fields of an entity with the fields in the hub or vice versa.

For information on data transformations, refer to Data Transformation. Click (Clear) to clear a data transformation.
Note: Use the IfExists instruction provided by the Data Transformation Modeler while defining data transformations for MDM. This instruction creates a traget element only if the source element is present.If this instruction is not used then empty elements will be created(in the target object)for those elements which are missing in source object. This could result in some issues while updating the database.
