The custom step includes options to specify:

the source directory
the source file pattern e.g. *.sas7bdat
the target directory
the period before which files should be archived
whether to move or copy files to the ZIP file
whether to do a "dry-run"

Python must be configured on the SAS Viya platform.

Usage

Demo

This short demo shows how to move two SAS datasets that match the filename pattern class*.sas7bdat to corresponding ZIP files named class*.sas7bdat.zip.

Custom step options

Section	Field	Default	Description
Source data
	Source directory	None	Source directory on the file system. Directories in SAS Content are not supported
	Source filename pattern	*	Filename pattern used to match files in the source directory e.g. *.sas7bdat. See the glob module for details
Target data
	Target directory	None	Archive directory on the file system. Directories in SAS Content are not supported
Archive period			Archive files with a last modified date-time before a given period. The period is specified as a number and a unit e.g. 1 month. The cutoff is calculated with dateutil.relativedelta
	Number	1	Number of periods
	Units	months	Period unit. Select from minutes, hours, days, weeks, months, years
Action
	Action	Move	Move or copy files to a ZIP file
	Dry run	False	If True, the step will run but not execute the archive step

Output

For each file in the source directory that matches the file name pattern and modified date-time constraints, a ZIP file will be created in the archive directory.

For example, if the following source files match:

Source	Archive
[source dir]/class.sas7bdat	[target dir]/class.sas7bdat.zip
[source dir]/classfit.sas7bdat	[target dir]/classfit.sas7bdat.zip
