Normally when a pipe requests data from a non-static input stream, that stream will first attempt to bring itself up to date, generating new stream sets as necessary, before supplying the data requested. However, if this field is ticked, the input stream will not run. Pipes from collectors cannot be marked as static.
Mandatory
If ticked, when multiple Streams are being merged then there must be an input record from this Pipe for an output record to be generated by the output Stream.

| Field | Description |
|---|---|
| Filter | Allows the user to set up a filter on the pipe. Also allows to set the flag to Include Superseded recordsAudit Records. If not set, superseded records will be filtered out. |
| Sort/Group | Specify the group/ order by attributes on the pipe. |
| Aggregate attributes | Specify any aggregate attributes on the pipe. |
| Advanced | Configure advanced features on the pipe. |

The following fields are available in the Basic Settings section if you set Data To Read = Custom:
| Field | Description |
|---|---|
| From Date Offset | The offset applied to the start of the collection period, relative to the period in the output stream that requires populating. |
| To Date Offset | The offset applied to the end of the collection period, relative to the period in the output stream that requires populating. |
| Max Stream Sets | In almost all cases this specifies the number of stream sets to be retrieved from the input stream. However, if this is a push pipe with positive offsets this value indicates the maximum number of stream sets that can be created i.e. the maximum number of cycles this pipe can initiate. |
| Only collect from same run | Every time the analysis engine runs, all of the stream sets that are created by all of the streams affected by that analysis run are given the same Run ID. If this flag is ticked then the pipe will only collect stream sets from the input stream that have the same Run ID as the stream set currently being created by the output stream. You should only use this flag is both the input and output streams are transactional. |
| Historied | If ticked, the pipe will collect data from the input stream by period. So if the from and to date offsets are both 0.0, and the output stream requires stream generation for the period 17/10/07 - 18/10/07, data will be collected from the input stream for the period 17/10/07 - 18/10/07. If not ticked, all data will be collected from the input stream, regardless of period. In this case, the offsets are still used to determine whether the required data periods in the input stream exist before the stream calculation can be carried out. |
| Read Future Data | If you are running a transactional stream then it is possible that while your analysis run is taking place, other analysis runs which started after yours may have managed to complete before yours, generating additional stream sets on the input stream. These additional stream sets will then have a future data relative to the date of the stream set you are generating. By default PhixFlow will ignore input stream sets that have a date in the future relative to the stream set being generated.
