Error importing SQL dump: Object is being imported by other transaction

Hi all,

I just encountered an awkward issue when I tried to move a database dump from one HANA system to another. I am getting the following error description:

SAP DBTech JDBC: [2048]: column store error: table import failed:  [30136] The object is being imported by other transaction

I imported an older dump earlier (and also a dependent DU) and suspected that this might interfere with the import, but after deleting the whole schema with cascade the error still persists. Does anyone know what might cause the error?

Thanks,

Michael
