Data for the feature is displayed incorrectly in the workspace
The Dataset Attribute workspaces can sometimes display incorrect data.
Issue
Values displayed in Dataset Attribute workspaces is inaccurate.
Workaround:
Examine the appropriate attribute from a different source program for example, ISPF, IDCAMS to determine whether the values are being displayed incorrectly. For example, a dataset that is displayed as having negative Free space might, in fact, show a larger amount of space Used than Allocated in its VTOC entry. This indicates that the VTOC is incorrectly updated in the past for example, a program reaches an ABEND abnormal end condition before correctly setting the values.
If the attribute displayed is incorrect, contact IBM® Software Support.
