Invalid primary data source

Hi all,

I tried to execute an Infopackage, I get the following error.

*Invalid primary data source'.

Datasource name : 1_BA_BA_CV_DA_Z_SDL_STTL

Detailed error message.

No other detailed information was available. Please let me know, whats the issue would be.

Thanks,
