I ask you for support with this problem. In this process I have each sales line marked to the production order and every now and then, randomly, when I go to release the sales lines of some items paid and ready to pack into the warehouse , I run the /Otubound load planning workbench/ function, the system block me and gives me the following error /Click cancel and select one or more lines to add to a new or an existing load/, has this ever happened to you? do you have any ideas?
