| # Pull call-off schedules A pull schedule of the type call-off is a referenced schedule that is triggered from the Assembly Control module, or from Warehouse Management ( Kanban, time-phased order point). The following steps are performed automatically based on the parameters and triggers: Step 1. To generate a schedule header A purchase schedule (header) is generated in the Purchase Schedules (tdpur3110m000) session. Because pull call-off schedules are usually preceded by a pull forecast schedule, LN searches for the corresponding pull forecast schedule in the Purchase Schedules (tdpur3110m000) session. Once found, LN creates a pull call-off schedule with the same schedule number as the pull forecast schedule. In this way, forecasting data and ordering data are separated. However, if the release type, defined in the Release Type field of the Purchase Contract Line Logistic Data (tdpur3102m000) session is set to Shipping Schedule Only, no forecasting data is generated, and the pull call-off schedule that is generated in the Purchase Schedules (tdpur3110m000) session, has no corresponding pull forecast schedule. You cannot manually update pull call-off schedules. You can only change these schedules from the origin that generated the pull call-off schedule. Step 2. To generate schedule lines Schedule lines are generated in the Purchase Schedule - Lines (tdpur3111m000) session. If the pull call-off schedule is triggered from Warehouse Management, the schedule lines in the Purchase Schedule - Lines (tdpur3111m000) session are generated from the Generate Orders (KANBAN) (whinh2200m000) session, or the Generate Orders (TPOP) (whinh2201m000) session. If the pull call-off schedule is triggered from Assembly Control and the release type that is linked to the pull call-off schedule is Sequence Shipping Schedule, the number of lines for each schedule can be enormous. For every item, a schedule line per call-off is generated in the Purchase Schedule - Lines (tdpur3111m000) session. However, sequence details such as VIN number, line station, and so on, are not stored in the Purchase Schedule - Lines (tdpur3111m000) session, but in the Sequence Shipping data (tdpur3517m000) session. To start this session, click Sequence Shipping data on the appropriate menu of the Purchase Schedule - Lines (tdpur3111m000) session. For more information on sequence shipping schedules, refer to To create and update sequence shipping schedule lines. Step 3. To generate a purchase release A purchase release is generated with the status Scheduled in the Purchase Releases (tdpur3120m000) session. With every generation of a schedule line, LN generates a release line detail record in the Purchase Release Line - Details (tdpur3522m000) session. This record has a one-to-one relationship with the schedule line and has the status Scheduled. If the schedule is a sequence shipping schedule, however, the following applies: Only a purchase release header is created. No purchase release lines and purchase release line detail records are created. The reason for this is that items in a sequence shipping schedule are required for a combination of vehicle number (VIN), line station, and assembly kit. For this reason, a link exists between the release header in the Purchase Releases (tdpur3120m000) session and the release lines in the Production Synchronous Calls (tdpur3523m000) session. The Generate Release per Vehicle or Generate Release per Item check boxes in the Purchase Releases (tdpur3120m000) session determine how the release is created: per vehicle, per item, or per business partner. For more information on purchase releases, refer to Purchase releases. Step 4. To print the purchase release The purchase release is printed in the Print Purchase Releases (tdpur3422m000) session. If the Communication Channel field in the Purchase Contract Line Logistic Data (tdpur3102m000) session and/or the Items - Purchase Business Partner (tdipu0110m000) session is set to EDI, and the Release EDI Message Directly check box in these sessions is selected, LN automatically prints the purchase release. Otherwise, you must print the purchase release in the Print Purchase Releases (tdpur3422m000) session. Step 5. To insert receipt details Receipt details are inserted in the Purchase Schedule - Receipts (tdpur3115m200) session. After receipts are confirmed in Warehouse Management, scheduled items can also be inspected. For more information, refer to To inspect scheduled items. Step 6. To insert cumulatives Cumulatives (CUMS) are inserted in the following sessions: Shipped Cumulatives (tdpur3131m000) Received Cumulatives (tdpur3132m000) Required Cumulatives (tdpur3130m000) Invoiced Cumulatives (tdpur3133m000) For pull call-off schedules, cumulatives are filled for information purposes only. Pull call-off schedules do not use cumulatives. Pull forecast schedules, however, which usually have the same schedule number as a particular pull call-off schedule, use the required cumulatives from the pull call-off schedule to calculate fab authorizations and raw authorizations. For more information on: Cumulatives, refer to Purchase schedule cumulatives. Authorizations, refer to Authorizations. Step 7. To reset the cumulatives and authorizations The cumulatives and authorizations are reset in the Reset Cumulatives (tdpur3230m000) session. For more information, refer to: To reset purchase schedule cumulatives To reset authorizations Step 8. To update history and turnover data Purchase schedule history and turnover data is updated in the Process Delivered Purchase Schedules (tdpur3223m000) session. As a result, the status of the schedule line is changed to Processed. In the Delete Purchase Schedules (tdpur3224m000) session, you can delete the processed purchase schedule.
