The update api for organizational payment methods (pay_org_payment_method_api / update_org_payment_method) shows some unpredictable effects.
In order to overcome that, i had
- to pass a null value for the p_sets_of_book_id, instead of the default value.
- to pass a value for a random pmeth_information column, instead of defaulting them all (and leave them out of the api call).
