Does anybody know why combine shipments is so slow when the customer has several orders some of which have many lines ? We have a customer that has no more than 3.000 sales lines and preparing the Invoice with "Combine Shipments" may take more than 4 hours. It seems that with every order it goes slower, slower, .... until it takes 30 seconds or more to change from one sales line to another. We're using NAV 2016.
What could I do ?
Thanks a lot.
