I created one production order qty 4 nos. Then end user activated,estimated, pick the item and posted, and report as finished,then end. But the end stage is not ended . I analysed quantity is 4 nos but serial is allotted 3 nos only one item serial no is missing but serial no is auto generated. How its missing, I could not find out. This mistake could have been occurred serial no missing and attached file for your reference. Kindly give me the solution.
