Main Exercises

Purpose: The purpose of this lesson is to balance the requisition demand of a manufactured component within the requisition demand of its parent parts.

Windows:
Batch Balancing
Batch Balancing/Parent Part Requisition
Shop Order Requisition
Shop Order Requisition/Shop Order

You are the person responsible for balancing and releasing the shop order requisitions for paint into balanced batches. Today you need to:

• Balance the requisitions for the various colors of paint to consume the batch of paint base to be made this week.
• Balance the paint end items (various colors of paint in different sized containers) with the batches of the various paint colors.
• Release the balanced batch of requisitions to create the shop orders.

Batch Balancing Paint Base

Balance the requisitions for the various colors of paint to consume the batch of paint base to be made this week.

1. Open the Batch Balancing window.
2. Query for the requisition created for the 81-400 part (paint base). Verify that the Parent Part Requisition tab shows the parent part requisitions for white, black, and gray paint.
3. In the table on the Parent Part Requisition tab, select the three requisitions that were created for this exercise. Verify that the Selected Qty field in the header displays 147 as the quantity needed of the component batch for the selected requisitions. In addition, the Remaining Qty field should display 53. This represents an under-utilized batch for the paint base.
4. You decide to increase the quantities on each of the three requisitions. In the table on the Parent Part Requisition tab, change the quantity for the 81-200 part to 120. Change the quantity for the 81-210 part to 65. Change the quantity for the 81-220 part to 80. Select the three requisitions again. Verify that the Selected Qty field is now 199.75 and the Remaining Qty field is 0.25. You decide this is close enough because you know that the yield, quantities per assembly, and other factors will not always result in an exact match.
5. Save the changes.
6. With the three records still selected in the table, right-click in the header and then click Create Balanced Batch.
7. Click Yes when the window about whether it is OK to continue when the quantity to balance does not equal the selected quantity displays.
8. Verify that the records in the table now have a value for the Balance ID field and that the value for Header Req No field matches the value for the Requisition No field in the header.

Batch Balancing End Items

Balance the paint end items (various colors of paint in different sized containers) with the batches of the various paint colors.

Note: You decide to balance the white paint first.

1. Click the Parent Part Requisition tab if it is not the active tab. Right-click the requisition for the 81-200 part (white paint) and click Call Batch Balancing to open a new Batch Balancing window.
2. In the table on the Parent Part Requisition tab, select the two requisitions that were created for this exercise for the 81-101 and 81-102 parts. Verify that the Selected Qty field in the header displays 78 as the quantity needed of the component batch for the selected requisitions. In addition, the Remaining Qty field should be 42. This represents an under-utilized batch for the white paint.
3. You decide to increase the quantities on both requisitions. Change the quantity for the 81-101 part to 8. Change the quantity for the 81-102 part to 5. Select the requisitions again. Verify that the Selected Qty field now displays 120 and the Remaining Qty field displays 0.
4. With both records still selected in the table, right-click in the header and then click Create Balanced Batch.
5. Verify that the records in the table now have a value for the Balance ID field that matches the previous balance ID and that the value for the Header Req No field matches the value for the Requisition No field in the header.
6. Close the Batch Balancing window for the white paint and return to the Batch Balancing window for the paint base.

Note: You decide to balance the black paint next.

7. Right-click the requisition for the 81-210 part (black paint) on the Parent Part Requisition tab and click Call Batch Balancing to open a new Batch Balancing window.
8. In the table on the Parent Part Requisition tab, select the requisition that was created for this exercise for the 81-112 part. Verify that the Selected Qty field in the header displays 42 as the quantity needed of the component batch for the selected requisitions. In addition, the Remaining Qty field should display 23. This represents an under-utilized batch for the black paint.
9. You decide to create a requisition for black paint in a different size container. Click the Query Where Used tab to see the other parts that use the 81-210 part as a component.
10. Select the record for the 81-111 part. Right-click and click Create Shop Order Requisition.
11. Click OK to acknowledge the message about the requisition.
12. Refresh the Batch Balancing window. Click the Parent Part Requisition tab and record the requisition number of the requisition just created.
13. For the new requisition for the 81-111 part, change the value for the Qty field to 11.
14. Select both requisitions. Verify that the Selected Qty field now displays 66 and the Remaining Qty field displays -1. You decide that this is allowable because you know the need for the fixed scrap quantity of 2 is only used when changing between paint colors and you will ensure that the one shop order for the black paint in 2 liter containers will directly follow the shop order for black paint in 20 liter containers.
15. With both records still selected in the table, right-click in the header and then click Create Balanced Batch.
16. Click Yes when the window about whether it is OK to continue when the quantity to balance does not equal the selected quantity displays.
17. Click OK when the window about whether with the message about the total quantity being less than the selected quantity displays.
18. Verify that the records in the table now have a value for the Balance ID field that matches the previous balance ID and that the value for the Header Req No field matches the value for the Requisition No field in the header.
19. Close the Batch Balancing window for the black paint and return to the Batch Balancing window for the paint base.

Note: You decide to balance the gray paint next.

20. Right-click the requisition for part 81-220 (gray paint) on the Parent Part Requisition tab and click Call Batch Balancing to open a new Batch Balancing window.
21. In the table on the Parent Part Requisition tab, select the two requisitions that were created for this exercise for the 81-121 and 81-122 parts. Verify that the Selected Qty field in the header displays 74 as the quantity needed of the component batch for the selected requisitions. In addition, the Remaining Qty field should display 6. This represents an under-utilized batch for the gray paint.
22. You decide to increase the quantities on the requisition for the 81-121 part. Change the quantity for the 81-121 part to 8. Select the requisitions again. Verify that the Selected Qty field now displays 80 and the Remaining Qty field displays 0.
23. With both records still selected in the table, right-click in the header and then click Create Balanced Batch.
24. Verify that the records in the table now have a value for the Balance ID field that matches the previous balance ID and that the value for the Header Req No field matches the value for the Requisition No field in the header.
25. Close the Batch Balancing window for the gray paint and return to the Batch Balancing window for the paint base.

Releasing a Balanced Batch

Release the balanced batch of requisitions to create the shop orders.

Note: Due to the dependencies between the levels, you decide to release the entire batch at one time. It would also be possible to release one level at a time.

1. Right-click anywhere in the header and click Release - Balance ID.
2. Close the Batch Balancing window.
3. Open the Shop Order Requisition window and query for the requisitions used and created during this exercise.
