I installed the AR connector from EMS store and connect it to our own SAP ECC environment. It will how not create the model views.

Hello Roan, thank you for reaching us out. Based on the error message, the cause of this error might be that there is no data extracted for table AR_BKPF (so the table is empty). Can you please check the extraction of AR_BKPF table if there is a message like: "Final count: Loaded 0 record(s)"? If yes, can you please check on your database: - Whether there are records within the AR_BKPF table and - If there are records, whether they are created after the specified start date (so not excluded via the FILTER condition).
