Encountered the same problem with the generation of sell-thru on Ninewest. Upon checking, the on hand is on zero value and the season code has two-letter code only and the quantity is also in zero value. Tried regenerating the file again but the same result has been generated. Checked it on JDA if the inventory on hand has a value, and upon checking there are36138 on the inventory. Consult Arvin regarding this and as per advised this is the same scenario with the problem on Superdry which is currently for chcecking.
