Ok, how would I access the debugger? again i’m only new to this and have inherited the role as the last person left quite abruptly, so i’m sorry if this is a basic question.
On the Journl you are trying to post, See if th transaction line and Field “General Posting Type” is filled.
One way to completely stop this error in future is if you are posting directly into your Chart of Accounts, you can set the Accounts as either SALES or PURCHASES.
