Invalid object error while installing migration services

Hi experts,

I m currently trying ton install SAP Best Practices for data migration. I am following the DM_ERP_Quick_Guide_EN_US_40.

I m facing an error in the step: 4.11 Install migration services tool.

When I try to add a staging area, by specifying the DM_REPO_ERP DataBase logon information, I get this error msg when I test the connection:

Invalid object name 'MGMT_PROFILE_HDR'.

Any suggestion would be helpful.

Thank you in advance.

Abdess,
