Hi Vikram,
If I can get you exactly you are talking about downloading data,
You can go for 'search all Master agreements' or 'Search all MA and Contract Documents'click on excel/pdf icon mentioned at top right corner and download it.
To Download specific Contract you go for 'Search master Agreements and Contract doucuments' click on specific CD and it will be auto downloaded.
The other way is exporting oma files, which is done in setup>system setting>export, go for options, data set/single object and export it.
Other way you can do via Workbook process which is a bit lengthy one.
Regards,
Ravi
