On previous systems I have used you can look at a nominal code and it will give you all transactions which relate to this in a simple easy format which when you click on it shows you the purchase invoice ect where the entry comes from.
On GP I go to detail enquiry then I have to select the Jnl Entry then in the jnl entry I need to select the source document and then look through the batch at each individual entry to see which one relates to the nominal code I am after.
Is there an easier way?
