MYOB reporting functionality isn't very good - best to download everything into Excel and create your reports from there. Extract the data using a trial balance report, and then create your desired report that pulls the required data from the trial balance. It can be quite complicated as often MYOB won't put the GL Account Codes into a separate column, but combine them with the GL Account Name, which is a pain, as you need to use a TRUNC formula to separate out the GL Account Code as a first step. Then you can create reports using the VLOOKUP function, using the GL Account Code as your item to search & match on.
