IdM 8 with Sybase and JPA

Greetings! I am trying to access the IdM db(deployed with Sybase) through JPA, but the JPA manager reports that all table/views (idmv_* / mxi_*) are missing their columns although I had generated the entities with the JPA generator.

The user we are connecting with is MXMC_rt. If I manually create a custom table under MXMC_rt and generate the entity with the JPA gen. I can use and access the table just fine.

Am I missing a permission? Or it is something related to the Sybase, because we are accesing the above mention IdM views/tables just fine with JPA+Oracle db

Our environment is:

Netweaver 7.31

JPA 1.0

Sybase 12 ASE

IdM 8
