Balance Requisitions

Explanation

Use this activity to balance shop order requisitions. Batch balancing is used for concurrent planning of components and end products. It is required when one component is used for multiple end products. Shop orders are created for each level. However you can balance only in the direction of child to parent.

After the balancing process a completely balanced requisition will show equal quantities in the Qty to Balance and Selected Qty fields. However, you can balance a requisition even if these quantities are not equal.

Caution: Do not create shop order requisitions prior to a batch balancing operation. If you do so, when you subsequently run MRP, the system may delete those shop order requisitions. To avoid this risk, wait until batch balancing is complete to create your shop order requisitions.

Prerequisites

This activity requires the existence of shop order requisitions for a part with a recipe structure.

System Effects

As a result of this activity, the system coordinates the lot sizes of the different shop order requisitions to make the total quantity of components match the quantity needed for the planned end products.
