Incomplete control parameter for commmunication

Hi ALL,

We have added a new field in generic data source in ECC and replicated to BI system.

Now when we executing info package ,it fails with the below error message

Incomplete control parameters for communication with the BW system.

Note:

I had already checked source system connection it's OK.

I am unable to laod for any data source.Therefore I understood it is connection problem.

Please help...
