Where can I find this? It doesn't seem to be included in data retention?
Can you provide a screen grab of the setting you are referring to.
These setting are applied for Abandoned Deliveries. The top setting however "Saved Transaction (days) applies to save transactions, you will also find this on the Form "Details" tab.
Please see the topic below which discusses Data Retention Management in Transact.
Data Retention Management
Yes, I assumed it was the time it takes before a submitted, but not completed transaction is set to abandoned.
But the data retention settings do not include this setting.
