I noticed an issue when I was executing OLMIS-6277: Not all processing periods that are available in the table are available in the "Processing Period" filter drop-down.
Log into the application as administrator.
Go to Reports > View Reports > Stockouts.
Compare the content of the "Processing Period" filter drop-down and of the "Processing Period" column in the "Reporting Rate and Timeliness" section.
The "Jan2017" and "Feb2017" periods are missing from the filter.
All processing periods visible in the "Reporting Rate and Timeliness" section should be available in the filter.
