This application suggests items for cross selling when a user selects any item from the buy or shopping items as part of order, as shown in following image.
By default it is using Groceries data set containing 30 days of real-world point-of-sale transaction data from a typical local grocery outlet with the items that are aggregated to 169 categories.
Item suggested is based on likely hood of possible based on what product is currently in the order and previous history of orders.
Choosing Item associations tab, one can view all the possible item suggestions learned from historical sales transactions, indicating strength of relation between buying of certain items leading to purchase of subsequent items. These can be analysed & filtered narrowed by appropriate confidence, support and lift factors as shown in following image.
It can accept user input data two column file in XLSX format as well as new data to create item association rules for shopping basket analysis and cross selling suggestions. For a SAP system it can be easily created by downloading Sales Items from table VBAP using Order Number as unique Transaction ID and Material as the Transaction Item two columns as shown in the image below.
It's logical to bundle this application as data product for end user . Since SAP HANA XS Administrator access for free trial version is unavailable to setup SQLCC, connection configuration so I had too ask for user's SCN or SAP ID and used it to add to list of authenticated users who could use this application and for any other user of the application, it errors out for lack of valid authorizations.
Which are most frequent or least selling items can be analysed interactively by selecting Frequently Sold Items tab as shown in image below.
