How to delete DTP requests?

Hi All,

I am deleting an data store object, but system is not allowing me to delete data store object, message 'datastore xxxx is not used externally' then it shows two dtp requets associated with this datastore.

How can I delete these dtp requests? How can I delete my data store object?

I have deleted all dtp, transformations etc.. still I am unable to delete my test data store object.

My system is on sp9(lastest).

Thanks and Regards,

Gnana
