ArcMap

ExtendedPropertyValue

Summary

ArcPy class that provides access to the individual cell for extended and linked properties associated with the job.

Discussion

Extended and linked properties store business-specific information as part of the job that is not covered by the default job properties. Extended properties have one-to-one (1-1) cardinality, and there is one set of properties associated with the job. Linked properties have one-to-many (1-many) cardinality, and there are zero or more sets of properties associated with the job. Extended and linked properties are stored in a nonsystem geodatabase table in the Workflow Manager (Classic) repository.

# Establish a connection to a Workflow database
conn = arcpywmx.Connect(r'c:\test\Workflow.jtc')

# Access a Workflow Job with extended properties
job = conn.getJob(99999)

# Get the extended properties table associated with the job
prop_table = job.getExtendedPropertyTable('wmx.extra_properties')
