Error: Multiple identifiers not supported for OnDevice driver

[sdeissenboeck]

I am receiving the following error when trying to query an entity from my odata service: 

Error: Multiple identifiers not supported for OnDevice driver

This is how my datastructure looks like (it's from the official SAP Asset Performance Management API)

Has any one ever faced this error before and knows a way to overcome it?

Thanks in advance!

Hello,

Thank you for reaching out to us. The on-device driver error you’re encountering typically occurs when the ID field is renamed. Renaming the ID field causes the resource configuration to break, as the rename does not update the identifier properties of the resource. Consequently, the resource still considers ID as its identifier, leading to issues down the line.

To avoid this, it may be worth considering that the ID field is clearly separated from other fields to prevent such conflicts. Let us know if further assistance is needed.
