Pull call-off schedulesA pull schedule of the type call-off is a referenced schedule that is generated from Assembly Control or from Warehousing ( Kanban, time-phased order point). The following steps are automatically performed based on the parameters and triggers: Step 1. Generating a schedule header A purchase schedule (header) is generated in the Purchase Schedules (tdpur3110m000) session. If the pull call-off schedule is 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 in the Purchase Contract Line Logistic Data (tdpur3102m000) session the Use Message Shipping Schedule or Use Message Sequence Shipping Schedule check boxes are selected, no forecasting data is generated. In this case, the generated pull call-off schedule has no corresponding pull forecast schedule. You cannot manually update pull call-off schedules. You can update these schedules only from the origin that generated the pull call-off schedule. Step 2. Generating schedule lines Schedule lines are generated in the Purchase Schedule - Lines (tdpur3111m000) session. If the pull call-off schedule is triggered from Warehousing, the schedule lines in the Purchase Schedule - Lines (tdpur3111m000) session are generated from the Generate Orders (KANBAN) (whinh2200m000), or Generate Orders (TPOP) (whinh2201m000) sessions. If the pull call-off schedule is triggered from Assembly Control and the schedule release type is Sequence Shipping Schedule, the number of lines for each schedule can be enormous. Therefore, for each item, a schedule line per call-off is generated in the Purchase Schedule - Lines (tdpur3111m000) session, but sequence details, such as VIN number and line station, are stored 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, refer to Sequence shipping schedules. Step 3. Generating a purchase release A purchase release is generated with the Scheduled status in the Purchase Releases (tdpur3120m000) session. With each 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 Scheduled status. If the schedule is a sequence shipping schedule, however, the following applies:
For more information, refer to Purchase releases. Step 4. Printing the purchase release The purchase release is printed in the Print Purchase Releases (tdpur3422m000) session. If the Communication Channel field is EDI in the Purchase Contract Line Logistic Data (tdpur3102m000) and Item - Purchase Business Partner (tdipu0110m000) sessions and the Release EDI Message Directly check box is also selected in these sessions, you need not print the purchase release in the Print Purchase Releases (tdpur3422m000) session. LN automatically prints the purchase release. Step 5. Inserting receipt details Receipt details are inserted in the Purchase Schedule - Receipts (tdpur3115m200) session. After receipts are confirmed in Warehousing, scheduled items can also be inspected. For more information, refer to Inspecting scheduled items. Step 6. Inserting cumulatives Cumulatives (CUMS) are inserted in these sessions: 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, refer to: Step 7. Resetting the cumulatives and authorizations The cumulatives and authorizations are reset in the Reset Cumulatives (tdpur3230m000) session. For more information, refer to Resetting purchase schedule cumulatives and Resetting authorizations. Step 8. Updating 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.
