ARM thinks it is mismatch somewhere and does not know how to deal with it

I need to figure out how they are handling rev rec for secondary books in general because maybe that could be causing the issue.

thinking the same thing at the same time 🙂

if they are using secondary book for IFRS - yes, likely that’s what it is

605 will not follow 606 rules and vice versa, and you want your 606 book to be right… look at the rev rec rules settings first and then see how they are used on items, then make sure dates on transactions are listed (fot good measure - ARM would give you dates specific error)

I assume you have it done in your 606 book. So do you have any errors on your Revenue Arrangements (Transacionts > financilas > revenue Arrangments)?

sorry, last one Update Rev Arrangments

it should show your errors there. Yes you want to check your rev rec plans, rev rec settings on items, and dates - that’s a ton to check, and you need to understand them in a sense that some setting do not go together, and there is no easy way to figure that out 😞
