The vendor capacity is only consumed if the following prerequisites are fulfilled:

• You have specified a consumption point in Customizing.
  This is the case if at least one of the following indicators is set in the IMG node Define source allocation control: either consumption point purchase requisition or consumption point purchase order.
• The procurement of a certain material takes place in the corresponding vendor capacity period.
• You have entered a value for the purchasing organization in the purchase requisition or purchase order.

The consumption point and capacity period are calculated for each schedule line. The consumption point is calculated from the delivery date of the purchase requisition/purchase order and the planned delivery times that are stored in the info record. The capacity period is then calculated based on this. The capacity consumption point is calculated as follows: Delivery date – (packing time + transportation time + capacity offset lead time in calendar days). The capacity is consumed according to the current conversion factor. A J_3APOCAP record is then created.

• Increase of the quantity in the purchase requisition/ purchase order
  If you increase the quantity after the capacity consumption has been executed, the subsequently added units of measure (delta) will be consumed as follows:

• If the conversion factor has not changed since the last capacity consumption point, the existing J_3APOCAP record will be updated.
• If the conversion factor has changed since the last capacity consumption point, the current conversion factor will be valid for the added units of measure. In this case a new J_3APOCAP record with sequential numbering is created for the delta quantity.

• Reduction of the quantity in the purchase requisition/purchase order
  If you decrease the quantity after the capacity has been consumed, all of the units of measure taken from the purchase requisition will be released again as follows:

• The release of capacities is carried out with the same conversion factor as the consumption.
• If the capacity has been consumed with different conversion factors, the units of measure that were consumed last are the first to be released, and the corresponding J_3APOCAP records are updated or deleted.

• Deletion of the purchase requisition/ purchase order
  If you delete the purchase requisition/ purchase order, the entire consumed capacity is released and the J_3APOCAP records are deleted.

If you convert a purchase requisition to a purchase order, the existing capacity records (J_3APOCAP) of the purchase requisition are copied to the purchase order. As long as you convert purchase requisitions to purchase orders without modifications, no further calculation will take place.

• Increase of the quantity of the purchase requisition to the purchase order
  If you increase the quantity in the purchase order that is specified in the purchase requisition, the quantity difference between purchase requisition and purchase order is consumed as follows:

• If the current conversion factor corresponds to the last conversion factor of the purchase requisition, the last J_3APOCAP record of the purchase order is updated.
• If the conversion factor has been changed, the new conversion factor is valid for the units of measure that have been added to the purchase order. In this case a new J_3APOCAP record with sequential numbering is created for the delta quantity.

• Reduction of the purchase requisition quantity in the purchase order
  If you reduce the purchase requisition quantity in the purchase order, only those J_3APOCAP records that correspond to the new order quantity are copied from the purchase requisition to the purchase order. The J_3APOCAP records created first are then copied to the purchase order first.

• Deletion of the Purchase Order

• If you delete the purchase order without deleting the purchase requisition, the capacity quantity of the corresponding, referring purchase requisition remains consumed. Only the J_3APOCAP records of the purchase order are deleted.
• If you delete the purchase order of an already deleted purchase requisition, the capacity quantity of the purchase order is released by deleting the J_3APOCAP records.
• If you reset the deletion indicator in the purchase order, the J_3APOCAP records are copied from the purchase requisition to the purchase order. If the order quantity is larger than the quantity of the purchase requisition, the quantity difference is consumed with the current conversion factor and the J_3APOCAP records are updated or newly created.

Capacity Consumption for Purchase Requisitions that have been converted to a Purchase Order (you have specified the purchase requisition as the consumption point in Customizing)

• The deletion indicator in the J_3APOCAP records for the purchase requisition quantity is reset.
• If the new purchase requisition quantity is smaller than or equal to the quantity in the related purchase order, the corresponding J_3APOCAP records are copied from the purchase order to the purchase requisition.
• If the new purchase requisition quantity is larger than the order quantity, the quantity difference is consumed with the current conversion factor and the J_3APOCAP records are updated or newly created.

When changing the delivery date in a purchase requisition or a purchase order, the capacity consumption date is recalculated. If the capacity consumption is then in a new capacity period, the capacity is released in the old capacity period and consumed in the new period.

If you change the vendor in a purchase requisition or a purchase order, the capacity at the old vendor is released and consumed at the new vendor.

If you change the delivery date or the vendor in the purchase order during the transfer of a purchase requisition to a purchase order, the capacity for the order quantity is consumed at the new vendor or in the new period. If it is only a partial conversion, the remaining quantity of the purchase requisition remains open and is consumed at the old vendor or in the old period.
