Rebate Condition Type does not appear automatically

Hi All,

I have a problem regarding a Rebate Condition Type in Billing, which is not appear in billing  document.

This case happen if :

While creating an Invoice, we change the billing date to the future (i.e year of 2019), so there will be no accounting document generated, save the invoice.

And after that we try to change again the billing date back to current date (i.e year of 2014), save the billing, so it will generate the accounting doc.

Now, if we check into the billing, Rebate Condition Type is missing.

Validity of the rebate agreement is up to year of 2019 (so it covers the future period).

Actually, this Rebate Condition Type can appear automatically if we just save the billing using the current date (without changing the future date).

I have checked some other threads before.

But most of them are mentioning about "no rebate condition type can be appear in billing document, although they do not update anything in that billing document"

So it's a bit different with our current case.

Any body know what might caused this Rebate Condition Type cannot appear only if I change the billing date to future?

Thank you

Best Regards,
