How to Match timestamp of Source & BW

Hi

The load failed after the deployment with following error. Can somebody explain me the reason behind this and how to resolve it.

we are using BW 3.5 and ECC 6

The DataSource Z_**_BTE_DELTA does not have the status of the source

system in the Business Information Warehouse.

The time stamp in the source system is 11/15/2008 22:06:04 .

The time stamp in the BW system is 11/07/2008 17:41:48

Thank You All
