Data Loading problem into ODS

HAI

Im trying to load the data into ODS .But im getting the following erre

<b>InfoIDocs missing; Database system

Diagnosis

InfoIDocs are missing. The Idocsim BW is created with the database systems as the source system. Since the IDocs are missing, a short dump in BW probably occurred.

System response

No selection information arrived from the source s

Procedure

Check the short dumps in BW.

Check the data in the InfoCube.

Troubleshooting

In the event that the data was updated correctly in the InfoCube, then it is possible that no Info-IDocs were created. In this case, manually set the entire status of the data request to "ok" (green traffic light) in the monitor in the Status tab page.</b>

I looked in sm37 . Job is cancelled.

Then i looked into ST22 . There it says some illegal datatype in FORM . But i dont have any Routine in the scenario

Please tell me wht i have to do
