Thesystem returns Migration File selected as table.
By default all the columns are included in the export.
If you want to skip certain columns, select Skip Export.
If you want to select only key and technical details select Skip All for Export.

Open the Mass Data Maintenance Tool in Silverlight and then try to access Import Log, it will allow you to open and download the same.
2. Once the csv file is uploaded in the tool, it cannot be archived or deleted.
3. This process is not used to nullify a field but only change an exisiting data for a record, refer case document : 1898866
Difference between Mass Data Maintenace and Data Migration:
Data Migration : Is like an initial load, but is not completely automatic. It is performed using CSV files (not webservices).
In this case you need to insert a "fake id" for each row you are going to import, just to identify each row and the relationship between them, but during the import, the system will simply ignore it, generating a new ID.
Mass Data Maintenance : The Mass Data Maintenance is completely different than the initial load and data migration (even though the UI interface is exactly the same of the data migration).
It is a way to modify a large amount of data, and is done via CSV files.
In this case you need to insert an ID for each row you are going to modify, and this ID must exist in the system.
