I want to see if I'm understanding the rules for Business Central Object ID Ranges. If I needed to create an extension that only affects one of our customers, I would use id's from range: 50,000 to 99,999. These id's do not need to be reserved, as the extension only exists at the one customer? Also, these id's would be free of charge? Indeed, if I wanted to, I could re-use the same id's for another customer extension as it too would only exist at the particular customer. Is this correct?
It is only if you were going to write an extension that is intended to be installed at multiple customers (via an App-Store / AppSource) that a different range would be required. I'm guessing this category would either fall into the 1,000,000 to 69,999,999 (RSP) range or the 70,000,000 to 74,999,999 (BC Apps) range. I'm not sure of the difference between these two?
