Noticed that a couple of issues do not show up in the ISSUERANKING table contains one (and only one) record for each issue that appears on any Agile board within Jira, and contains a field indicating that issue’s direct ordinal child issue ID.
Various theories could be if the issue is removed from JIRA or present across boards then this could lead to conflicts and hence resulting in an issue not being mapped to a rank.The remove scenario makes sense, but the issue being present across multiple boards should be a common scenario. Would like to know what is exactly happening.
