Post AR Invoice to different GL account based off product group code

We’d like to eliminate the manual journal entries to get Capital Lease and Operating Lease lines on misc invoices flow to their specific AR Accounts (10606 and 10603). Everything currently flows to the general AR account of 106100. I posted a deeper dive here: Change Debit AR Account Based on Part Number - #16 by askulte

Do you recall what unintended side effects you had? Modifying posting rules is new to us, and we’d like to avoid those unintended side effects! Thanks for your input.
