Overview

Each time you run analysis on a model, PhixFlow creates a new set of data in for each stream. You can view the stream sets and the data they containthis data by right clicking on a table on an analysis model and selecting 

Insert excerpt
_record_sets_show
_record_sets_show
nopaneltrue
; see Managing Recordsets. Stream sets  for more options.

Recordsets remain available until you run an archive task on the stream; see Task. 

If there is a problem during the analysis run, you may find that a stream set has incorrect or missing data. To fix stream sets, you can undo the analysis by running rollback. There are several options available to configure rollback; see Using the Rollback Window, below.

This has been removed as it doesnt add value the options are explained below?

  • Either rollback deletes the specified stream set(s).
    You cannot repopulate a deleted stream set.
    Use this approach when you want to completely discard a stream set. When you next run analysis, PhixFlow creates a new stream set with the latest data.

  • Or rollback deletes the data but keeps the stream set itself. Tick the Keep old stream sets option to use this option.
    The stream set remains on the stream set list, marked as incomplete. You can repopulate an incomplete stream.
    Use this approach when you want to fix the data in a stream set. When you next run analysis, PhixFlow repopulates the incomplete stream set; see Repopulating Incomplete Stream Sets, below. 

For large data sets, it may take some time to rollback all the data in a stream set.

Using the Rollback Window

In the Rollback window, select an option and specify the stream sets to rollback.

OptionDescription
Rollback a number of StreamSetsEnter the number of stream sets to roll back. PhixFlow removes this number of stream sets, starting with the most recent.
Rollback to a specific run

Enter the run ID of a stream set to which you want to rollback. You can find the run IDs in the Managing Recordsets. PhixFlow removes all the streams from the most recent, up to and including the specified run ID.

For a transactional stream, PhixFlow removes the specified run ID only. All other stream sets, even more recent ones, are retained. 

From DateEnter a date. PhixFlow removes stream sets whose period start date is more recent than the specified date.
Rollback all dataPhixflow removes all stream sets for this stream.
Keep old Stream sets

This box is ticked by default.

Repopulating Incomplete Stream Sets

If you rollback data due to errors, you can repopulate an incomplete stream set with the correct data. This is because the all stream sets in a model that were created during the same analysis run have the same Run ID. PhixFlow can use the run ID to pull the correct data into an incomplete stream.

Tip

Make sure you have corrected any problems that caused the error before repopulating the stream set with data.

To repopulate an incomplete stream set:

  1. Go to the console.
  2. Find the log messages related to rollback.
  3. Right-click the log message and select Repeat to reinstate data; see Rollback or Repeat Cycles Window.

For information about rerunning incomplete stream sets in an transactional stream; see the Managing Recordsets → Reprocess StreamSet option.
