Change repayment terms of some loans

Changing the payment method and / or date is only possible on loans that are TO_REPAY or TO_REPAY_FEES.

Postponing loan repayment date is only possible once, except for some financial products with customized rescheduling rules. An overall ceiling (configurable per financial product, 30 days by default) from the original contractual date still applies regardless. Repaying earlier is never restricted.

If loan is supposed to be repaid using a sepa direct-debit, you may not be able to change the debited account number less than 3 days before the scheduled payment date because payment has already been instructed. In such case you'll get a 400 error telling you that the payment cannot be cancelled anymore.
