Hi,
so no bin is assigned to the work center? OK, that could only be one. In case of QM, well, yes, you do not really do much in the work center, so probably at first you do not get an error message. But sooner or later you want to create the WT for putaway, don't you? I guess then you have to have a bin.
For the other thing you are trying to do: the work center shows bins in the inbound and the outbound section, also when they are empty. Maybe you should look into this. But: if you then move the HU with drag and drop from one bin to another, the HU is moved, that means there is no open WT anymore. Is that what you want? Does the quality inspector just have to enter this in the work center and the physical movement is already done or is simply then done by him? Or do you need someone to receive a WO and do the physical movement?
