AX OLAP Cube Setup – Transaction Date not Saved

Today I saw an issue with the AX Cube definition manager not saving a new value for “Transaction date” on the measures tab. A user makes a change but when they go back to check it’s not saved. This only occurs when the user follows a specific sequence of actions, the steps to recreate and the solution…


Performance – SysDeletedObjects40 – Keep updated Objects

One of the key performance improvements that can be implemented for AX4 (and should apply to AX2009 also) is to disable the SysDeletedObjects40 (label is “keep updated objects” in en-us) configuration key. In older version of AX, memo fields were used on a lot of the main tables (memo field can cause performance issues), in…


Performance – memo/ntext fields

This week I saw an issue with an AOS which was consuming too much memory (~1.8gb) and then throwing users off.Put simply this was because in the server configuration utility, database tuning tab, the maximum buffer size was set too high.
