Currently, agreed security withholdings are not taken into account in automatic payment plans. There are two ways to improve: (easy and faster to implement): Security withholdings incurred so far are deducted from the next planned invoice (or deducted from the last one) - this brings the payment plan up to 0. (more complicated to implement). All scheduled payments are reduced by the discontinued SE. In the summary below, a distinction is made between an SE that has already been completed and an SE in a planned invoice. At the end, a compensation payment SE is added to the payment plan.
