Commitment item for down payment and bank clearing account

Hello Experts,

We are now implementing ECC 6.0 and online payment update function in fund management government module. (Of course, online split function is already activated)

I have one question on down payment for you.

I would like to post some down payment amount using F-48 standard down payment transaction like below.

Dr) Down Payment xxx / Cr) Bank Clearing xxx

When I looked into SAP Help site, it said that payment information will be updated as soon as above bank clearing account is cleared by bank account.

But, unfortunately, the above bank clearing document won't update the original down payment document in our system.

So, I would like to know which kind of Financial trans. and Commitment Item Cat. is good for above the commitment item of down payment account.

Currently, Financial trans. is 30 and Commitment Item Cat is 3 in our system.

Is that correct?

BR,

Chris Kim
