File based Segmentation HV

Dear All

Have been searching SDN from last one days but couldnt find a answer.....

I am trying to create a DATA SOURCE using origin type FILE EXPORT , in this regards i have few questions which i am unable to find solution..

- Whats the name that should be given for data source ? it seems it has a link to file which will be uploading to TREX..

if i try to give a name like "test" and try to select BP fields, i get an error "No values found for data source specified " and NAME field is changed to "NDatasourcea"

Now if i try to use report CRM_MKTTG_FDS_LOAD_FILE_UI , i dont find any datasource for selection....

Do we have a way to place the file in the TREX path manually and execute the program??

Thanks

Sweta
