EPBCS Metadata Load Error – Unrecognized Column Header Values for Entity Dimension during DM Export

Summary:

We are experiencing an issue while loading metadata into EPBCS. During the metadata import, we receive the following error:
Unrecognized column header value(s) were specified for the "Entity" dimension: 
OEP_FS Consol op. OEP_REP Consol op. FIN_INPT Consol op. FIN_REPT Consol op. OEP_CPX Consol op."
Not used for Cube Not used for Cube Addition Not used for Cube Addition

Are these valid metadata properties for the Entity dimension in EPBCS?
Is there a supported way in Data Integration?
Has anyone encountered similar issues when exporting metadata into EPBCS application?
