Infor® Data Lake utility will only attempt to add the schema objects once per table. The Data Warehouse has 18 preconfigured, out-of-the-box tables. After the initial attempt fails, the Infor® Data Lake utility will not retry adding the schema objects until you manually "touch" the table in the Data Lake schedule (going inactive and then reactivating). If adding IONCE after your EAM tenant is provisioned, you must manually update all 18 tables.
Once the Schedule is activated, data will be polled from EAM for populating to the Data Lake. This is not a retroactive process. As such, older data that was created prior to activation of the schedule is not exported, unless you manually "touch" or update the data in some manner.
