Having the job code in AP is very important as two of my customers want to know how much is due by a job basis to their creditors. I use Crystal Report for Adagio to extract this information by using the reference field in the AP transaction. It serves some results but not good enought. I have been looking at this solutions since the days of Accpac Dos with Quick report for Windows.
For your information I also had highlighted to Softrak on the availability of this code in Adagio AR. In AR with Crystal Report I have been helping my customers in analysing the debts outstandings by job code.
