This question is in reference to Atlassian Documentation: Setting up service desk reports
Why can a custom field not be used in the report filter when it's only applicable for the specific project? --> the field is greyed out in the selection and there is a hint displayed "field not applicable for project/issuetype" even if both are correct (the only service desk project in the instance and the only issuetype in this project)
Example:
Configuration:
custom field: office --> single select (office A, office 
field context: only applicable for project "JSD1" and issuetype "problem"
project "JSD1" only uses issuetype "problem"
Scenario:
Trying to configure a report in project "JSD1" which shows issues created for office A vs. issues created for office B.
Problem:
Field "office" can not be selected in the filter.
Note: When the field context is specified to all projects and all issuetypes (global) it works.
