Adding the subsidiary record is easy. But if you have integrations running like it sounds like, adding those in could be tricky. Some things you'd need to watch out for: 1. If you have security role(s) that have access to all subs, you'll need to go add the new sub to those 2. Same with GL Accounts, Departments/Classes/Locations/Custom Segments if you're not using the "include children" box on any of those 3. If you use multi-sub vendors and this sub needs to use some of them, you (or someone) will have to manually add that sub to the vendor since for some reason there's no way to do this via CSV. I assume it could be scripted? 4. If you're running multi-book, a reporting currency will need to be specified for the new sub and it will be inactive until you do so. 5. If you don't already have an elimination sub in the "node" this sub is going to be in, you may need to add one 6. Printed/emailed forms may need to be adjusted depending on how they're set up. I assume if you have 19 subs already, that's been taken care of that's off the top of my head. If i think of more, I'll let you know.
