CI autofill removal (when creating DPR)

Dear experts,

Down Payment Request creating (f-47 txn) provides default CI on screen.

How may I change it or make it empty by default on screen?

Details:

F-47

I choose:

Type KA

Date, account...

Target spec GL ind = F,

in the next screen the filed Commitment Item has automatic value on screen.

(I have no rule at FMDERIVE)

Where does it come from?
