In my industry, we make plastic products such backet, bowl,basket .... etc. Production make backet (green),(red),(yellow) such as.

eg. we own in Inventroy Backet (red) 200, Backet (yellow)400, Backet(green) 100... Then we make the Packing, our packing process with 12 item(dozen). That mean it include red, yellow, green, blue that is radomize. After Packing Backet (red),Backet(yellow), Backet(Blue) that all name into change "Backet" only.

If i packing Backet (red) 120, that reslut now Backet 200.

Now i just tell my problem now.

In packing i make packing process Inventory>Packing(Small->Big)>CREATE>Add Line in:Operation> package - Save etc i am going. Now problem is strated, somtime i Validate  the stage, if i only Backet (red) 120 only, but there were 2 row in Product Move. I don't know why.
