  1. In the repository browser, expand the list of Datasources.
  2. Drag the datasource called Rating and Billing into your model.
  3. In your model, hover your mouse pointer over Rating and Billing and click 
    Insert excerpt
    _show_tables_show
    _tables
    nopaneltrue
    . PhixFlow displays a list of the tables available in this database. You can resize the list to make it easier to browse.
  4. Right-click on SOURCE_PACKAGE_CHANNELS and select 
    Insert excerpt
    _create_collector
    _create_collector
    nopaneltrue
    . PhixFlow adds a new database collector  to the model, and gives it the same name as the source data table, SOURCE_PACKAGE_CHANNELS. In the settings → Basic Settings section → Statement Expression, you can see the database query is: 
      select * from SOURCE_PACKAGE_CHANNELS.
  5. Hover your mouse pointer over the new database collector, and click 
    Insert excerpt
    _add_stream_with_attributes_add
    _stream_with_attributes
    nopaneltrue
    . PhixFlow adds a new stream to your model and also gives it the name SOURCE_PACKAGE_CHANNELS. In the settings → Attributes section, you can see that the data has two attributes (columns): Package and Channel.
  6. To load the data into the stream, run analysis on this section of the model and check the data has loaded.

    1. Hover your mouse pointer over the SOURCE_PACKAGE_CHANNELS stream , click 
      Insert excerpt
      _run_analysis
      _run_analysis
      nopaneltrue
       then click YES to confirm.
    2. When PhixFlow notifies you that the analysis is finished, hover your mouse pointer over the stream again.
    3. Click

...

  1. Hover your mouse pointer over the Latest Package Update stream and click 
    Insert excerpt
    _stream_add
    _stream_add_stream
    nopaneltrue
    .
  2. In Basic Settings, set the Name to Latest Package All Channels.
  3. Drag all the attributes from Latest Package Update to the settings for Latest Package All Channels.

    titleHow?
    1. Hover your mouse pointer over the stream Latest Package Update.
    2. In the context toolbar, click 
      Insert excerpt
      _stream_attributes
      _stream_attributes
      nopaneltrue
      . Phixflow lists the data attributes (column titles) for this stream.
    3. Select all the attributes and drag them into the Latest Package All Channels settings → Attributes section.


  4. Click 
    Insert excerpt
    _finish
    _finish
    nopaneltrue
     to save and close the settings tab.
  5. Close the attributes list.

...

  1. In the model, add a pipe from SOURCE_PACKAGE_CHANNELS to Latest Package All Channels. PhixFlow opens the settings for the new pipe.
  2. In the Basic Settings section, set:
    • Name: find_channels
    • Type: Look-up
  3. In the Order/Index section, click 
    Insert excerpt
    _stream_attributes
    _stream_attributes
    nopaneltrue
    . PhixFlow opens two lists of attributes: one list for the source stream and another for the receiving stream. 
  4. From the source stream list, on the left, drag PACKAGE into the Order/Index grid.

    This tells PhixFlow about the key column in the source stream. Notice that PhixFlow has added a line to the Order/Index grid.
  5. From the receiving stream list, on the right, drag Package over the top of the line in the Order/Index grid.

    This tells PhixFlow about the matching key column in the receiving stream. Notice that PhixFlow has now added the Index Expression _outPackage. However, we do not want PhixFlow to use _outPackagebecause output multipliers are calculated before the output is generated. We need it to use the data on the input.
    This means that the lookup will match records in the reference data (SOURCE_PACKAGE_CHANNELS) where PACKAGE = Package from the input pipe in
    We must do this, rather than using the value of Package from the output because we are GOING TO USE the lookup to drive an output multiplier – and output multipliers are calculated before the output is generated

  6. In the Order/Index section, double-click the new line that PhixFlow has added. PhixFlow opens the settings for the PACKAGE attribute. Set:
    •  Basic Settings → Index Expression from _out.Package to in.Package.
    • Click 
      Insert excerpt
      _finish
      _finish
      nopaneltrue
       to save and close the settings tab.
  7. Close the attribute list.
  8. In the pipe settings, click 
    Insert excerpt
    _finish
    _finish
    nopaneltrue
     to save and close the settings tab.
  9. In the model toolbar, click 
    Insert excerpt
    _save
    _save
    nopaneltrue
     to save your model., which should look like this:

At this point, if you run your model (I think) it will find each customer, e.g. C010, and will read that the customer has the News package. It will then look-up the channel for this to find News: Channel 1. But having done one look-up for the customer it will move onto the next customer.This means that the lookup will match records in the reference data (SOURCE_PACKAGE_CHANNELS) where PACKAGE = Package from the input pipe in
We must do this, rather than using the value of Package from the output because we are GOING TO USE the lookup to drive an output multiplier – and output multipliers are calculated before the output is generated
 

Set an output multiplier

An output multiplier tells PhixFlow to process the same record multiple times, each time producing a new record. This is called breaking-out a record. In this case we want PhixFlow to keep processing the same customer record until it has found all the channels. This means our single input record:

...

  1. In the model, double-click Latest Package All Channels to open its settings tab.
  2. To create the output multiplier, expand the Multipliers and Filters section and set:
    • Output Multiplier: find_channels.CHANNEL
  3. To create a new column for the channel data, expand the Attributes section. Click 
    Insert excerpt
    _add_object
    _add_object
    nopaneltrue
     to add a new attribute. PhixFlow opens a new attribute settings tab. Set:
    •  Name: Channel
    •  Expression: _outputMultiplier
  4. Click
