Delete one of the lable files

You need to find your AX AOS install directory. Usually C:\Program Files\Microsoft Dynamics AX\50\Application\Appl\[Instance Name].



From this directory, if your label file is LBL in AX:

Stop the AOS

Delete all of the

axLBL*.ald,

axLBL*.alc,

axLBL*.ali

files

Start the AOS



The ALD files are "Application Label Data", ALC files are "Application Label Cache", and the ALI files are "Application Label Index" files.



When you create a new label, say @LBL123, it will often store it in the ALC file until at some point AX decides to flush it from the cache file into the ALD file. When you stop the AOS, it flushes these for you, and you can do it manually in AX too (Label::Flush("LBL", "en-us").



The part right after axLBL[here].ald, is the language for the label file. English label files for example are:

axLBLen-us.ald

axLBLen-us.alc

axLBLen-us.ali
