Default Baseline Date RE: Post Incoming Payment

Hi Experts,

I am using t-code REEXF_28 and noticed that the default baseline date that the system puts on the cleared item when I simulate the transaction is the document date. This should not be the case since based on the configuration of payment terms the posting date should be the default baseline date.

The master data used has due immediately as payment terms. Invoice Posting has blank payment terms.

I've checked the configuration of Payment terms via OBB8. The posting date was ticked as the default baseline date.

I try changing the default for baseline date just to check if the configuration is working but unfortunately it does not change the date that is defaulted on the baseline field via t-code REEXF_28.

So my question are:

1) Is the configuration in OBB8 not work in t-code REEXF_28?

2) How is the default baseline date configured in REEXF_28?

Please help me...

Thank you in advance!
