Add a Stage File Action to Write Modified Records into a New File

Add a second stage file action to read individual records of each file, modify or transform them, and write the modified records into a new file.

1. On the right side of the canvas, click Actions and drag and drop the Stage File action inside the For_Each_InputRow action. Placing this stage file action within the second loop ensures that each record in a file under iteration is read.

   The Configure Stage File Action dialog is displayed.

2. On the Basic Info page, enter a name for the action (Write_Row). Click Next.
3. On the Configure Operation page, enter the following details.

   Field	Information to Enter
   Choose Stage File Operation	Select Write File.
   Specify the File Name	Click Edit to build an expression to specify the name for the new file that is created. Let's build an expression such that the names of the new individual files are: their old names plus the suffix, - modified. In the Source tree, select the filename field present under $OneTextFile > ICSFile > Properties (this represents the old names of the files), and click Move to populate the Expression field on the right. Add a comma after filename and enter '-modified'. Enclose the entire expression in parenthesis and prefix the term concat as follows: concat($OneTextFile/nsmpr2:ICSFile/nsmpr2:Properties/nsmpr2:filename, '-modified') Click Save and then Exit Expression Builder.
   Specify the Output Directory	Click Edit to build an expression to specify the output directory, where the files will be written. Type the following expression into the Expression field: '/tmp/zip-test/staged/modified'. Click Save and then Exit Expression Builder.
   Append to Existing File	Select to append records to the existing file.

   Click Next.

4. Leave the configurations on the Schema Options page as they are. Click Next.
5. On the Format Definition page, perform the following actions to upload a file from which to create a schema.

   Field	Information to Enter
   Select the Delimited Data File	Click Choose File and upload the test-file1.txt file you created. See Create a Sample Zip File. The content of the file is then displayed at the bottom of the page.
   Enter the Record Name	Enter the name you want to assign to the records in the schema file. This becomes the parent element in the created schema file for the record names selected as column headers from the CSV file. Enter ModifiedRow.
   Enter the Recordset Name	Enter the name you want to assign to the recordset in the schema file. This becomes the root element of the created schema file. Enter ModifiedRowSet.
   Use the First Row as Column Headers	Deselect this check box.

   The rest of the fields are automatically populated from the uploaded CSV file. Click Next.

6. On the Summary page, review the data you've entered and click Done.
