Past 10 days have seen most informative and good articles across our Blogosphere. Another one has proved to be one such article.
Check this article from Merit Matters: What is an Item Type?
It just explains what are all the Item Types available and its meaning. Well, you can read this on the readily available GP manuals, but this article adds some experience and correlated information to the basics. For instance, it starts with the necessity of understanding GP Cards and with that starts explaining this Item Type as an instance. Slowly it dives into the other aspects of setting up an Item Type, such as the scope of each type.
Clearly a MUST READ article.
