Infopackage failure

Hi friends,

One of the loads of infopackage failed and the message that im seeing is. Here its a 3.5 version. In the update tab its

Check: No successful initialization of the delta update took place

Message no. RSM683.

When I checked the data source in ECC  using RSA3 im getting this message.

DataSource 0TCT_DSA1 is not defined in the source system

Please share your ideas on this.

Thanks,

Ravi
