The consumption of the patients once they were sent to collect must beeliminated, this is because if, for example, we have already charged for this consumption and the patientreturns, we will see that the consumption continues and we will, for example, add otherconsumptions, then what will happen is that this consumption is going to be added to theconsumption that we already charged and it will seem to us that it was not charged,so if the consumption has already been charged, we already send it to a new sale, whatwe must do is eliminate it and if it was already subtracted from the stock, It happened through asale, we can eliminate it without subtracting it or we can eliminate it and subtract it from the stock,this so that we can later addproducts and not charge for products that have alreadybeen invoiced.
