Hi,
I've installed the addon "eInvoicing & Payments". Since then, I'm not able to create customers without giving an "Account Receivable" and an "Account Payable".
I've checked out another question on this topic (on this site but i dont have enough karma to post links). In the other question it is replied "These are property fields, which you can make non-mandatory by a simple inherit.", but it did not help me to find the way to do such a thing.
I've taken a look in "Technical -> User Interface -> Views", trying to find these property field, but I could not find anything.
Any help will be much appreciate! Cheers VG
