If you want to enter a cash journal with gross amounts, you have to do this through the business partner module - which is quite complicated for a normal general ledger entry.
You cannot enter gross amounts (incl. VAT) in the general ledger.
Our customers cannot understand why it is not possible to enter gross amounts in the GL.
Dear Jphkaitan. Thank you for your answer. And yes, the journal generates VAT entries by itself (general parameter VATLINGNR). It is very hard for our customers to understand, why they cannot enter gross amounts. They have to enter petty cash entries by the AP/AR modules instead of the General Ledger.
Becaue Journal entries do not generate VAT entries by itself and the capturer has to enter the VAT entries too. The system gives a warning to that effect too.
