If a newly added relation does not appear in the creditor drop-down on the purchase booking screen, there may be a few underlying reasons for this.
The relation will appear in the drop-down only when:
- Expected costs (such as goods, commission, transport, or order) must be added for the relation, or
- The relation must be marked as “direct to ledger account” in the relation root data screen.
If neither of these conditions is met, the relation will not be available in the drop-down.
Additionally, ensure that at least one address is added to the relation and marked as billing so that the relation can be used on any screen. For more details refer to this FAQ
