Unable to define default field in quotation

hi,

I am trying to configure default field in “quotation” card.
i have selected comm/propal/card.php , i want to put payment terms as 15 days by default for every new quote. i have made the entry as shown in snapshot attached. but it is not working. i think the field name(cond_reglement_id) or value “15D” is not correct. like wise i want to configure payment type, availability delay.

please suggest field names and values

Hi, your payment terms can be set here: Dictionary setup - Payment Terms

No dear, in setup we have default values/sorting option. I want to add fields snd values there
