Push schedules

A push schedule is a nonreferenced schedule that can either be generated by a planning system, or created manually. In both cases, the same procedure is followed.

For push schedules, the following steps must be completed:

Step 1. Generating a schedule header and lines

Create/generate a schedule header in the Purchase Schedules (tdpur3110m000) session, and schedule lines in the Purchase Schedule Lines (tdpur3111m000) session.

LN generates a new schedule only if Enterprise Planning does not find an existing push schedule for a combination of item, warehouse, buy-from business partner, ship-from business partner, and purchase office.

Before a pull forecast schedule can be automatically generated by Enterprise Planning, the following information is exchanged between Enterprise Planning and Purchase Control:

  • Determination of supplier

    To determine a supplier:

    1. Enterprise Planning sends the required item (group) and warehouse to Purchase Control.
    2. Purchase Control searches for approved suppliers based on the priority levels defined on the Buy-from BP Search tab in the Purchase Schedule Parameters (tdpur0100m500) session.
    3. Purchase Control sends all valid business partners to Enterprise Planning, after which Enterprise Planning selects a supplier.

    When searching for a contract line in the supplier selection process, the warehouse for the plan item in the Items - Planning (cprpd1100m000) session is used. When searching for a purchase contract line detail, this warehouse must be part of the same cluster as the purchase contract line detail's warehouse in the Purchase Contract Line Details (tdpur3101m100) session. For more information, refer to Overview of purchase contract handling and Corporate purchase contracts.

  • Determination of requirement dates
    To determine the requirement dates, Enterprise Planning carries out lead time offsetting. To carry out lead time offsetting, you must generate planned delivery moments far enough in the future in the Generate Planned Delivery Moments (tdipu0225m000) session. The generated planned delivery moments are stored in the Planned Delivery Moments (Shipment Based) (tdipu0125m000) session or the Planned Delivery Moments (Receipt Based) (tdipu0126m000) session, from which they can be called on by Enterprise Planning. For more information, refer to Using planned delivery moments.
  • Determination of supply
    When determining the supply, a number of constraints can prevent Enterprise Planning to generate or update nonreferenced purchase schedule lines.

When generating a push schedule in the Purchase Schedules (tdpur3110m000) session, a blanket warehousing order is created immediately. You can view blanket warehousing orders in the Warehousing Orders (whinh2100m000) session.

Step 2. Regenerating schedule lines

Regenerate schedule lines in the Regenerate Schedules (tdpur3211m000) session.

For push schedules, schedule line regeneration serves the following purposes:

  • To determine the applicable segment set and pattern code as retrieved from the Purchase Contract Line Logistic Data (tdpur3102m000) session and/or the Items - Purchase Business Partner (tdipu0110m000) session, and to update the buyer.
  • To calculate the schedule line's new requirement type based on the applicable segment set and issue pattern. As a result, the schedule line is moved in time.

For more information on using segment sets when regenerating purchase schedule lines, refer to Using segment sets.

Step 3. Generating a purchase release (line)

Use the Generate Release Lines (tdpur3222m000) session to perform the following actions for Material Release and/or Shipping Schedule:

  • Generate purchase release lines, which are displayed in the Purchase Release (tdpur3121m000) session. For more information, refer to Purchase releases.
  • Cluster schedule lines, which are displayed in the Purchase Release Line - Details (tdpur3522m000) session. For more information, refer to Clustering purchase schedule lines.
Step 4. Approving the purchase release line

Approve the purchase release line in the Approve Release Lines (tdpur3222m100) session.

Step 5. Printing the purchase release

Print the purchase release in the Print Purchase Releases (tdpur3422m000) session.

If the Communication Channel field is EDI in the Purchase Contract Line Logistic Data (tdpur3102m000) and Items - 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 6. Inserting authorizations

Authorizations are inserted in the FAB/RAW Authorizations (tdpur3534m000) session.

For more information, refer to Purchase schedule authorizations.

Step 7. Inserting receipt details

Receipt details are inserted in the Purchase Schedule - Receipts (tdpur3115m200) session.

For more information on receiving and inspecting scheduled items, refer to:

Step 9. Resetting the cumulatives and authorizations

Reset the cumulatives and authorizations in the Reset Cumulatives (tdpur3230m000) or Reset Cumulatives by Contract Total Line (tdpur3230m100) sessions.

For more information, refer to Resetting purchase schedule cumulatives and Resetting authorizations.

Step 10. Updating history and turnover data

Update purchase schedule history and turnover data in the Process Delivered Purchase Schedules (tdpur3223m000) session. As a result, the status of the schedule lines is changed to Processed.

In the Archive and Delete Purchase Schedules (tdpur3224m000) session, you can delete the processed purchase schedule lines.

Note

You can use the Purchase Schedules (tdpur3610m100) session to filter the purchase schedules that require attention and to execute the appropriate actions on the schedule lines. For example, schedule lines that are almost due and are yet to be received, or lines whose due date ( planned receipt date) has passed.
