Error code: 0x80044331, Message: A validation error occurred. The length of the 'cr01c_odata_drl1' attribute of the 'cr01c_requests' entity exceeded the maximum allowed length of '100'

so i extend cr01c_odata_drl1 to 1000, the warning resolved , but i still cant update the cds if i refresh the fata flow m why? im thinking of deleting the data flow and re create it ,will this work and will it delete my original table in cds ?

Hi @Anonymous ,

If you delete the data flow, it will not delete the data in the CDS.
You could try to recreate the data flow.
If you still have any question, please don't hesitate to let me know.

Deleting a Dataflow will not delete the table and its data. When you create a new Dataflow you can map it to the existing table created from your first Dataflow. Before you delete though, what's the error message from the runs after you updated the length to 1000? You can see it by clicking the little warning icon next to the last refresh date:
