Accessing a barcode value from the Workflow tool
One method to access a barcode value from the Workflow configuration tool is to use a VBScript with
the Open Script task, using the Watch.ExpandString command with a Metadata command as its input
parameter, in between double quotes. For example, the following script line gives the value of the first
BarcodeValue Metadata field of the first datapage:
watch.expandstring("GetMeta(BarcodeValue[0],0,Job.Group[0].Document[0].Datapage[0])")
Another method is to use a Set Job Infos and Variables task to copy a Metadata field into a Workflow
variable.
Limitations
l
Some barcodes created with PlanetPress 5 could not be read by the Barcode Scan task, so
please use PlanetPress version 6 or 7 to create barcoded documents.
l
When using a secondary input, a known issue of the Workflow Tool can cause some unexpected
behavior, like having the same Metadata file reused instead of a new one being created for each
data file captured. To work around this issue, simply add a Rename action task to set a unique
file name (Ex. %u) to each new file before the Barcode Scan task, after each secondary input.
Change Emulation
Change Emulation action tasks are used to tell the tasks that follow them to use a different emulation
to format the data they receive (see: "About data emulation" on page54). These tasks do not perform
any operation as such on the data, but rather they modify the way subsequent tasks process the data
they receive.
Change Emulation action tasks are typically used when a secondary input task brings new data that is
not structured like the initial data into the process. By default, every task included in a process uses the
emulation associated with the sample data file to structure the data before processing it. Any task that
must use a different emulation must be preceded by a Change Emulation action task. All the tasks
that follow on the same branch will use the emulation chosen in the Change Emulation task.
Input
Any data file.
Processing
The emulation for the following tasks is changed to the selected emulation.
Output
The original data file, metadata and job infos are not modified. Only the emulation is changed.
