This page explains the various reasons why a worklog is invalid. The Status column in any list view shows if the worklogs are invalid and for which reasons. The Advanced Timesheet and any of its views, have a standard Invalid Worklogs filter available.
Issues with invalid worklogs are displayed with an Invalid Worklogs label, at the end of the issue line in timesheets. This accounts for the User, Advanced and the Issue Timesheet (if Include sub-tasks is ticked).
The List View showing Invalid Worklogs reasons in the Status column
The table below explains the three reasons why a worklog can become invalid.
Status
Description
Issue is Invalid
This message is displayed if a required field is missing, according to the set Expression on the Fields screen.
For example if the Expression has been set to the value fixVersions, the JIRA Issue Fix Versions/s field has become required.
For example if the Staff ID User Property is configured to SSN, but lacking in the JIRA's User Property settings for a user, the Staff ID missing message is displayed on worklogs entries for this user.
External message
The last type of message in the Status column is if Tempo data is synced with an external system. The message is either OK or some error message from the external system.
