Partial Reload - Partial Reload is used to Add a new table without reloading existing tables in Qlikview file and also we can replace the existing table in Qlikview file.
Suppose if you tables A and B already loaded into Qlikview file, then we can use Partial Reload to add Table C without reloading Tables A and B again.
Also you can replace existing table with new table. Suppose if you Table A then during reload you can replace the Table A with new data.
Incremental Reload - It is used to reload only the modified/new records between the current and previous reload.
Partial reload executes a specific part of your sciprt, this can for example be used to refresh a certain table.
Incredemental reload is defined in the script to update certain tables incredementally, for example to add only new transactions to a transaction table.
Incremental reload is especially used to decrease the reload time, by for instance only loading new records from a data source instead of the complete table (which can be very big).
