There was an issue of BioStar2 v2.4.1 for T&A users&user group.

Relevant problem

Case 1)

The T&A report of BioStar2 is not generated when a user selects [User group] to see the T&A report in accordance with the selected user group. The problem won't occur when you select a user only.

Case 2)

The user group information of BioStar2 AC are different from the user group information of BioStar2 TA.



It's BioStar2 TA bug of BioStar 2 v2.4.1. It has been fixed to v2.5.

But, the problem will be kept even though you upgrade your system to v2.5 or higher veresion than v2.5 if you do not update current status.
