The Inside Microsoft Dynamics GP blog has started a series Feature of the Day posts for Microsoft Dynamics GP 2016 R2; as the most recent versions have been, these posts are in the form of PowerPoint slides; I am reposting them here so they can be read more easily.
The series index for this series of posts is here.
The fifteenth Feature of the Day is Save Fixed Asset ID with Suffix.
This feature puzzled me a little, as I thought you could already do this, so I gave it a quick try in 2016 R1. You can do it, but GP doesn't really want you to.
