A - What you need to do is to "Close the Work Order". In this case, you completed 31 in operation 10, but only 30 in operation 20 and 30. So we presume you had a scrap quantity of 1 during the production. You have two ways to close the work order:
Method 1 - Close the Work Order Directly
Go to Production Transaction and report quantity 0 for operation 30 (the last operation, or the "Y" count point,) and indicate it is "Closed." By doing this, the system will need to clear out the extra materials and labor in Operation 10 from the WIP account and go to WIP variance account.
Method 2 - Scrap it and Close the Work Order
Go to Production Transaction and report quantity 1 scrap at Operation 20. By doing this, the system will clear out the extra materials and labor in Operation 10 from the WIP account and move it to the Scrap account. Then enter production transaction for Operation 30 with quantity 0 and indicate it is "Closed." This will close the work order.
Below are step-by-step sample screens for Method 2.
Enter production transaction for operation 20 and indicate the "quantity scrapped" = 1 and post it.
Enter production transaction for operation 30 and indicate the "quantity complete" = 0 and "order complete" = "Y"
After you post this production transaction, you will notice this work order is complete in the work order inquiry and there's a scrap at Operation 20. See sample screen below.
