## Specific flow parts to build

You can find here a menu allowing you to select one or multiple flow parts you want to build. Add here:

- *1: Transactions preprocessing*: if you want to build datasets present in the flow-zone [transactions_preprocessing](flow_zone:3La1CrK).
- *2: Association rules computation*: if you want to build datasets present in the flow-zone [association_rules_computation](flow_zone:2SNOOIG).
- *3: Association rules filtering*: if you want to build datasets present in the flow-zone [association_rules_filtering](flow_zone:b0BsCoE).
- *4: Customer recommendations*: if you want to build datasets present in the flow-zones [recommendations_preprocessing](flow_zone:1QYvNls), [cross_sell_recommendations](flow_zone:X2Yv1zo) and [repeat_purchase_recommendations](flow_zone:cSRQcI9).


Add all parts if you want to build all the flow.

Note: No matter if you change the order of the parts to build: they will be processed in the order 1 -> 2 -> 3 -> 4.


## Build specific flow parts

By clicking on the *BUILD SPECIFIC FLOW PARTS* button, DSS will take into account all the parameters set in the application to build all the datasets present in the chosen flow parts.
