Defining value formulas
Formulas are expressions that determine a value's contents. They
are evaluated by the software during the scanning or when a
batch/document is being created.
Formulas can be used to:
- (Re)name a batch or a document (see: Project setup, Indexing,
Setting batch/document names)
- Automatically fill in index fields (see: Project setup, Indexing,
Defining index fields)
- Identify the type of document ((see: Project setup, Indexing,
Defining batch/document types)
An expression is made of variables and a literal part.
Variables are predefined values that are computed by
IRISPowerscan at runtime. They can be:
• The username (<USER_NAME>)
• the id (<STATION_ID>) or the name (<STATION_NAME>) of
the station
• the id (<BATCH_ID>) or the name (<BATCH_NAME>) of the
current batch
• the id of the current document (<DOCUMENT_NUMBER>)
• the id of the current page (<PAGE_ID>)
• the current date and time
• any OCR value (<OCR_label of the OCR zone>)
• any barcode value (<BC_label of the BCR zone>)
E.g.: The formula <BC_Separator>":"<OCR_Language> is the
concatenation of an barcode zone, a literal (":") and an OCR zone.
