Can't able to find IDoc CREMAS.CREMAS04

Hi Friends,

I'm trying to follow the steps for creating a vendor from a flat file (File to IDoc) but when I select "Import of RFC and IDoc Interfaces from SAP Systems Permitted" in Software component version, I should able to see the "CREMAS.CREMAS04" IDoc under Imported Object-->IDoc. I don't see "CREMAS.CREMAS04" under IDoc, what could be the reason?

I'm connecting to correct SAP R/3 system.

Thanks for help!
