Question
Why is there no Default Purchase Type to select on the Purchase Ledger Transaction Account settings?
Answer
The reason that there is no default purchase type to select on the Purchase Ledger transaction account is that the box VAT reporting by tax type box in the company structure is unticked under the enterprise.
To tick this, go into Administration > company structure, click on the enterprise tick the VAT reporting by tax type box and then click Save.
Now if you go back on to the Accounts > Purchase Ledger > Master Account and click on to the transaction account tab, the option for a default purchase type on the transaction account should then appear.
