EDI business document Schedule

The following types of purchase schedules exist:

• Push schedule
  A list of time-phased requirements, generated by a central planning system, such as Enterprise Planning or Project that is sent to the purchase business partner. Push schedules contain both a forecast for the longer term and actual orders for the short term. A push schedule is a nonreferenced schedule.
• Pull forecast schedule
  A list of time-phased planned requirements, generated by Enterprise Planning, that is sent to the purchase business partner. Pull forecast schedules are only used for forecasting purposes. To order the items, a pull call-off schedule must be generated with the same schedule number as the pull forecast schedule. Similar to a push schedule, a pull forecast schedule is also a nonreferenced schedule.
• Pull call-off schedule
  A list of time-phased specific requirements of purchased items, triggered from Assembly Control, or Warehousing (KANBAN, Time-phased order point). A pull call-off schedule is a referenced schedule.

The purchase schedule can be sent through the following purchase releases:

• Material release
  A schedule on which forecast information is provided about shipping times, delivery times, and quantities. In general, a material release can be considered as a planning release. For push schedules, the material release can also include the actual order. In this case, the release is called a material release with shipping capabilities. A material release can include push schedules or pull-forecast schedules.
• Shipping schedule
  A schedule on which detailed information is given about shipping times or delivery times and quantities. A shipping schedule facilitates just-in-time (JIT) management. A shipping schedule can include push schedules or pull call-off schedules.
• Sequence shipping schedule
  A supplement to the material release or the shipping schedule with precise information about the production or deliveries of the requirements. This schedule can include the production or delivery sequence, the order, the place, and the time of unloading after shipment. A sequence shipping schedule can only include pull call-of schedules.

Consequently, the business document schedule includes these messages:

• MRL
  Material Release
• SHP
  Shipping Schedule
• SEQ
  Sequence Shipping Schedule

To prepare EDI messages for push schedules in a purchase release:

1. Create a purchase schedule header in the Purchase Schedules (tdpur3110m000) session and purchase schedule lines in the Purchase Schedule - Lines (tdpur3111m000) session.
2. Create a purchase release line in the Release Lines (tdpur3222m000) session.
3. Approve the purchase release line in the Approve Release Lines (tdpur3222m100) session.
4. Print the purchase release in the Print Purchase Releases (tdpur3422m000) session with the Final Report and the Prepare EDI messages check boxes selected.

A pull forecast schedule can be generated only from the Generate Order Planning (cprrp1210m000) session in Enterprise Planning and cannot be created manually. Based on the parameters and triggers, the following steps are carried out automatically to prepare EDI messages for pull forecast schedules in a purchase release:

1. A purchase schedule header is generated in the Purchase Schedules (tdpur3110m000) session and purchase schedule lines are generated in the Purchase Schedule - Lines (tdpur3111m000) session.
2. A purchase release is generated in the Release Lines (tdpur3222m000) session.
3. The purchase release is approved in the Approve Release Lines (tdpur3222m100) session.
4. The purchase release is printed in the Print Purchase Releases (tdpur3422m000) session.

A pull call-off schedule can be generated from Assembly Control through the Transfer Assembly Part Supply Messages (tiasc8220m000) session, or from Warehousing through the Generate Orders (KANBAN) (whinh2200m000) or Generate Orders (TPOP) (whinh2201m000) sessions. A pull call-off schedule cannot be created manually. Based on the parameters and triggers, the following steps are carried out automatically to prepare EDI messages for pull call-off schedules in a purchase release:

1. 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, a pull call-off schedule is created with the same schedule number as the pull forecast schedule. In this way, forecasting data and ordering data are separated. If no forecasting data is generated, the pull call-off schedule, as generated in the Purchase Schedules (tdpur3110m000) session, has no corresponding pull forecast schedule.
2. Schedule lines are generated in the Purchase Schedule - Lines (tdpur3111m000) session. If the release type that is linked to the pull call-off schedule is Sequence Shipping Schedule, a schedule line for each call-off is generated in the Purchase Schedule - Lines (tdpur3111m000) session, but the sequence details for a particular call off, such as VIN number, and line station are stored in the Sequence Shipping data (tdpur3517m000) session.
3. A purchase release is generated with the status Scheduled in the Purchase Releases (tdpur3120m000) session. With every generation of a schedule line, a release line detail record is generated in the Purchase Release Line - Details (tdpur3522m000) session. This record has a one-to-one relationship with the schedule line.

   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, because 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.
   • Depending on the settings of the Generate Release per Vehicle and Generate Release per Item check boxes in the Purchase Releases (tdpur3120m000) session, the release is either created by vehicle or by item or business partner.
4. The purchase release is printed in the Print Purchase Releases (tdpur3422m000) session.

When EDI messages are processed, this data is generated:

• A sales release with revision number one in the Sales Releases (tdsls3512m000) session. If a new EDI message is received for an existing sales release, a sales release revision is created with revision number two, and so on.
• Sales release lines in the Sales Release - Lines (tdsls3508m000) session.
• Sales release position details in the Sales Release Position Details (tdsls3515m000) session, for referenced schedules of the Shipping Schedule type. The Schedule Revisions for Referenced Shipping Schedules check box in the Schedule Terms and Conditions (tctrm1131m000) session determines whether sales schedule revision numbers are used for referenced shipping schedules. If this check box is cleared and if you receive an update of a referenced shipping schedule, no new sales schedule revision number is created. Instead, the sales schedule is updated. If an update arrives for a sales schedule line, also the sales schedule line is updated. To keep track of the updates, LN files the sales schedule line updates as revisions in the Sales Release Position Details (tdsls3515m000) session. Consequently a sales release position detail refers to a sales schedule line.
• A sales schedule with a sales schedule revision number of one in the Sales Schedules (tdsls3111m000) session. If new requirements are received for an existing sales schedule, a sales schedule revision is created with revision number two, and so on. The previous sales schedule revision and its requirements are no longer valid after the new sales schedule revision is approved.
• Sales schedule lines in the Sales Schedule - Lines (tdsls3107m000) session.
• Sequence shipping information in the Shipping Sequence (whinh4520m000) session, and shipping sequence detail revisions in the Sequence Shipping Information (tdsls3517m000) session, provided the schedule is referenced and of the Sequence Shipping Schedule type.
