Business Content Installation

Hello to all,

I have a problem while installing Business content.

As per SAP Documentation...I selected the Cube and selected Before and After grouping option. Ex: 0CSAL_C01.

I checked the dependent objects under Info Objects for 0CSAL_C01. For some of the objects it's selected MATCH (to prevent overwrite and this is set as default).

Then I installed in back ground mode option.

Once the installation is done the 0COSTCENTER is overwritten (even if I selected Match option and it de-selected Install).

Can any one please explain me why this is happened? Any documentation on it?

Does background mode not recommended? Does it always overwrite???

Thanks
