Bring data into your workflow by selecting a file or connecting to a database (optionally, using a query).

  • Data lives OUTSIDE the workflow
  • Values update (are dynamic)
  • Must export workflow to share files
  • Data is configured based on the file type being imported
  • Close all input files to avoid errors
  • Previews the first 100 rows of data from the selected file

Q

The tool is not configured correctly & needs to be corrected in order for the workflow to run correctly.

A

What do Exclamation Marks on Tools mean?

30
Q

(1) Record Limit
- Improve run times
- Manually type number of records to input

(4) Output File Name As Field
- Add a column showing source file name or full path
- Easy to identify and use source info in workflow

(5) Delimiters
- Manually enter delimiters

(6) First Row Contains Field Names
- Deselect if columns do not have names

(7) Field Length
- Default is 254 Characters
- Manually change the length of a column to avoid truncated values

(8) Start Data Import on Line
- Avoid importing extraneous information from data sources
- Enter the line on which data values start

(9) Ignore delimiters in
(10) Treat Read Errors as Warnings

(11) Code Page
- Data can be encoded with a particular format (ex. UTF-8 or Language)
- Select the correct code page for your data

(12) Allow Shared Write Access
