When setting up and maintaining scripts, DotActiv does not get involved.
Should you have any questions as to the content of the data and the staging table as well as how it all works, DotActiv can assist.
Also, when it comes to populating the staging tables, DotActiv has the option where you can provide the CSV files in a specific location. DotActiv has scripts that extract it from the location to the staging table.
However, these scripts are pre-defined. DotActiv does not provide scripts to extract data from your systems.
