When trying to use the 'Merge' tool in ArcCatalog [EDIT (v. 10.3.1)], I am not seeing all of the merge rules- the options I can select are different than those outlined in the tool's 'About' section. Can anybody tell me why this might be? In particular I would like to use the 'Join' rule to create an output merging individual records with corresponding field values without just appending one table onto the end of another as is currently happening.
In the image below, you can see from the dropdown merge rules which are available in contrast to those that the tool is telling me should be available on the right. The order is different and 'Range' appears to have replaced 'Join'. Do these tools perform the same function?
