SSIS and Parameters and where to set them

 SSIS has a LOT of ways to set configs. Parameters & variables, and then those can be overridden at different levels.

in order (from lowest to highest) - bottom of this list supercedes the top. You can see WHERE it was overridden because at that level, the parameter name is in bold. 

1. SSIS Package level
2. SSIS Project level
3. XML Configs? (I don't remember where these can be set)
4. SSISDB - right-click on the project within integration catalog and choose "Config"
5. SSIS Job Step configuration
