Consider the following scenario in Dynamics SL. You apply a cumulative update (CU). However, when you open the Database Maintenance screen you notice that the update scenario is not the correct SL version.
This behavior will occur when the modified date of the existing dbbuild.ini is newer that the modified date of the dbbuild.ini contained in the CU.
Contact Microsoft Dynamics SL support to obtain a dbbuild.ini for the current cumulative update.
