using ODATA using $batch API

Hi World!!

I am creating a job in CPI, which updates the email, I use the SF Employee Central entity PerEmail. At the time of running CPI, it gives me the errors:

com.sap.gateway.core.ip.component.odata.exception.OsciException: Request Payload Parsing Failed for one of the reason: (1) Either the OData metadata content available in the server is outdated OR (2) The request payload seems to be incorrect. Error Details: Entity Set batchParts not found in the edmx.

any ideas?
