1. Using an Administrator role, navigate to Setup > Company > Auto-Generated Numbers > Document Numbers tab > Sales Order, kindly check the following:
Value of Initial Number
Value of Current Number
Allow Override checkbox = T
When you create a new Sales Order:
1. The Order# field (ID: tranID) is automatically populated with the next value set on the Current Number under Auto-Generated Numbers. Since Allow Override = T, user can override value here.
2. If the user set a value on the Order# field which is lower than that of the Current Number, the value of the Current Number under Auto-Generated Numbers is not updated.
For example, the user created a Sales Order #2, since the last SO Document Number created was #5 (value of Current Number), the Current Number under Auto-Generated Number will be #6 and the next Sales Order # will also be #6.
3. If the user set a value on the Order# field which is higher than that of the Current Number, the value of the Current Number under Auto-Generated Numbers is updated.
For example, the user created a Sales Order #10, even though the last SO Document Number created was #5 (value of Current Number), the Current Number under Auto-Generated Number will be updated to #11 and the next Sales Order # will also be #11.
