This article provides a solution for a slow Lasernet archive button when you try to select the Lasernet dropdown menu from a Journal in AX 2012.

The reason for the slowness in the dropdown menu is that the database has a Compatibility level that is set to SQL 2014. This then makes our index on the LACArchiveRef table incorrect.  

Resolution

1. Check if index ArchiveRefRecId is created on table LACArchiveRef.

2. If it is not, import the attached XPO (zip file) or change the database Compatibility level to 2012.
