Purchase schedule cumulatives

Purchase schedule cumulatives (CUMs) are used for these purposes:

  • Keep track of a schedule's total ordered and received quantities
  • Calculate overdeliveries and underdeliveries for push schedules
  • Inform the supplier on the received quantity

Cumulatives

In Procurement, these CUMs are supported:

  • Shipped cumulatives, which can be viewed in the Shipped Cumulatives (tdpur3131m000) session.
  • Received cumulatives, which can be viewed in the Received Cumulatives (tdpur3132m000) session.
  • Required cumulatives, which can be viewed in the Required Cumulatives (tdpur3130m000) session.
  • Invoiced cumulatives, which can be viewed in the Invoiced Cumulatives (tdpur3133m000) session.

When a purchase schedule is released, LN inserts records in the previously mentioned sessions in this order:

  1. A shipped cumulative record is inserted/updated when an advance shipment notice is received from the supplier. The shipped quantity communicated by the supplier is inserted.
  2. A received cumulative record is inserted/updated when a receipt is made in Warehousing. The actually received quantity is inserted.
  3. A required cumulative record is inserted/updated when a receipt is confirmed in Warehousing. The total required quantity for the schedule line(s) is inserted.
  4. An invoiced cumulative record is inserted when an invoice is approved in Financials.

In general, cumulatives are calculated and updated based on schedule number, CUM reset date, and transaction date, which can be the shipment date, receipt date, planned requirement date, or invoice date. The schedule number and the transaction date are determined when the transaction takes place.

Note: 
  • The Process ASN During Goods Receipt and Update Shipped CUM for Receipts without ASN check boxes in the Purchase Schedule Parameters (tdpur0100m500) session also affect the method of updating the cumulatives.
  • You can reset the cumulatives in the Reset Cumulatives (tdpur3230m000) and Reset Cumulatives by Contract Total Line (tdpur3230m100) sessions.

Cumulative models

In the CUM Model field of the Purchase Schedule Parameters (tdpur0100m500) session, you can specify how the communicated cumulatives are used in company.

These CUM models are available:

  • Receipt based CUM model

    In receipt based schedules, the supplier's position is taken into account. In case of an underdelivery, schedule lines with a planned requirement date that falls before the next schedule issue date are inserted as immediate requirements in the Purchase Release Line - Details (tdpur3522m000) session. Furthermore, the total received CUM is communicated to the supplier.

  • Order based CUM model

    Order based schedules are independent of the supplier's position. In case of an overdelivery or underdelivery, suppliers are responsible for calculating their position in relation to the demand. Consequently, all ordered quantities are communicated to the supplier, after which the supplier subtracts the shipped quantity from the ordered quantity. For more information on how the supplier handles underdeliveries and overdeliveries, refer to Adjusting sales schedules.
Note: For push schedules, goods are usually received against a blanket warehouse order and the purchase release usually contains clustered schedule lines. Received goods are distributed across the schedule lines with the oldest unfulfilled requirement of the type immediate or firm. For more information, refer to Clustering purchase schedule lines.

Example

Schedule Number 10000001

Requirement date Position no. Ordered Qty. Received Qty. Requirement type Price
11/01 10 5 pieces 0 pieces Firm 10
12/01 20 5 pieces 0 pieces Firm 10
13/01 30 5 pieces 0 pieces Firm 10

If, on 10 January, a receipt is confirmed of seven pieces (receipt 0001, packing slip 001), this data is updated:

  • The purchase schedule lines are selected in the sequence of oldest unfulfilled requirement of the type Firm. Consequently, first receipts are booked on the requirement of 11 January, then on the requirement of 12 January , etc. Receipts can be booked on schedule lines for a maximum of the ordered quantity.

    In our example, a receipt of seven pieces is booked as follows:

    • 11 January : although seven pieces are delivered, five pieces can be received on this line.
    • 12 January: although the ordered quantity is five pieces, only two pieces of the actually received quantity are assigned to this line (five pieces are assigned to the schedule line of 11 January, which is older). This means that this line is only partially delivered.

  • The purchase schedule lines are updated in the Purchase Schedule Lines (tdpur3111m000) session:

    Requirement date Position no. Ordered Qty. Received Qty. Requirement type Price
    11/01 10 5 pieces 5 pieces Firm 10
    12/01 20 5 pieces 2 pieces Firm 10
    13/01 30 5 pieces 0 pieces Firm 10

  • The receipt details are updated in the Purchase Schedule - Receipts (tdpur3115m200) session:

    Position no. Receipt no. Packing slip no. Received Qty. Approved Qty Rejected Qty
    10 RCP0001 PS001 5 pieces 0 0
    20 RCP0001 PS001 2 pieces 0 0

  • Planned inventory transactions are updated in Warehousing:

    Position no. Receipt date Quantity
    10 11/01 0 pieces
    20 12/01 3 pieces
    30 13/01 5 pieces

  • The received cumulatives are updated in the Received Cumulatives (tdpur3132m000) session:

    Receipt no. Packing slip no. Transaction date Received quantity Received CUM
    RCP0001 PS001 10/1 7 7

  • The required cumulatives are updated in the Required Cumulatives (tdpur3130m000) session:

    Planned requirement date Required quantity Required CUM
    11/01 5 5
    12/01 5 10
