In this exercise you will compare the Stream stream you created in the previous exercise, listing all channels for each customer, with a list of assigned channels stored in an inventory database. To do this, you will create a lookup directly from a Database Collector:database collector:

  • Open the model Channel Package Check
  • Add a new Stream stream to your model from Latest Package All Channels, called Channel List Reconciliation
  • Drag all the attributes from Latest Package All Channels into Channel List Reconciliation
  • Create a Database Collectordatabase collector, using the Datasource datasource Inventory DB, to read all records from the table SOURCE_ALL_CHANNELS_LIST
  • Add a lookup pipe from the Database Collector database collector SOURCE_ALL_CHANNELS_LIST to the stream Channel List Reconciliation
    • Call the pipe invIn the matching attributes form create a match:
    • Go to the Order/Index section
    • Press Image Added
    • Drag the attribute CustomerRef from the right hand box into the list of matching attributes
    • Drag the attribute CustomerRef from the right hand box into the list of matching attributes again – on top of the matching attribute CustomerRef you created above – this will populate the right hand part of the matching attribute
    • Create another matchDrag Channel from the right - hand box into the list of matching attributes
    • Drag Channel from the right
    • -
    • hand box into the list of matching attributes again - on top of the matching attribute for Channel that you created above

This lookup will find values in the external database table which match the output records on CustomerRef and Channel

  • Press  in the main pipe configuration form to save your changes
  • Open the configuration form for the Stream stream Channel List Reconciliation
  • Add an attribute with Name InvoiceCheck
  • In this Attributeattribute, you will record whether you returned the channel from the inventory table - to do this, you will count the records returned from the lookup; if this is 1, you will record that the reconciliation check was successful:
    • Set the Expression of the Attribute to:

  • Save your changes to the Streamstream
  • Run Analysis analysis on Channel List Reconciliation
  • Review the results, and see which channels reconciled against the list from the inventory database, and which did not
    • Remember that you can open the data in the external inventory table using the CenterView PhixFlow schema browser – if you want to verify the results
