To calculate a requested delivery time in 'CO Type. Update Field Selection' (OIS014/E), you can either enter a default requested delivery time, or the amount of hours and minutes needed from now on to calculate a requested delivery time. Values are entered in the Requested delivery time field.
The Requested delivery time field in 'CO Type. Update Field Selection' (OIS014/E) indicates the default requested delivery time, which is proposed on the customer order (OIS100/E). If the entered time is followed by a + sign (01:00+), it indicates the time (hours:minutes) to add to 'now' to calculate a requested delivery time. This calculation also considers the number of days entered as the Minimum processing time in (OIS010/F).
Leaving the field Requested delivery time empty, an order will be created with 'now' as the requested delivery time. The order will be considered to be in the past after one minute passed, which could have some negative consequences in the customer order process.
