Adapters in grey status in Runtime workbench

Hi All,

I have a query related to the status of Adapters in Runtime workbench.Currently the status of all the adapters in the runtime workbench is <b>Grey colour</b>.

I have done the following:

1)Try to reimport the SAP_BASIS content 6.40

2)Tried to change something in adapter and then activated it again

3)Checked the adapter engine cache through sxi_cache and refreshed it.

4)Checked the sender agreement correctness.

5)Checked whther file adapter is activated or not.

Problem still persists.

Question : <b>Can some body suggest what else I should do to rectify the error.</b>

Thanks & Regards

Prabhat
