EDI business document Schedule

LN supports the following types of purchase schedules:

• Push schedules
  A push schedule is a list of time-phased requirements, generated by a central planning system, such as LN Enterprise Planning or LN Project that are 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 also called a non-referenced schedule. A non-referenced schedule is a schedule that contains lines without a reference number. Because no specific requirement exists for the schedule line, non-referenced schedule lines can first be clustered (grouped to send the lines in one purchase release) and then ordered, shipped, and received together.
• Pull forecast schedules
  A pull forecast schedule is a list of time-phased planned requirements, generated by LN Enterprise Planning, that are sent to the purchase business partner. Pull forecast schedules are only used for forecasting purposes. To actually order the items, a pull call-off schedule must be generated with the same schedule number as the pull forecast schedule. Like a push schedule, a pull forecast schedule is also a non-referenced schedule.
• Pull call-off schedules
  A pull call-off schedule is a list of time-phased specific requirements of purchased items, triggered from Assembly Control, Shop Floor Control, or LN Warehousing ( Kanban, time-phased order point). A pull call-off schedule is a referenced schedule. A referenced schedule contains lines with reference numbers. When goods are shipped, received, and invoiced, the reference numbers are used to communicate with suppliers and other LN packages. Because a specific requirement exists for the schedule line, each single schedule line is ordered, shipped, and received separately.

The purchase schedule can be sent by means of 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, however, the material release can also contain the actual order. In this case the release is called a material release with shipping capabilities. A material release can contain 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 contain 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, and the order, the place, and the time of unloading after shipment. A sequence shipping schedule can only contain pull call-of schedules.

As a result, the business document schedule includes the following EDI messages:

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

To prepare EDI messages for push schedules in a purchase release

Complete the following steps 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 only be generated 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 only be generated from Assembly Control by means of the Transfer Assembly Part Supply Messages (tiasc8220m000) session, or from Warehousing by means of the Generate Orders (KANBAN) (whinh2200m000) and the 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, 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. 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, line station, and so on 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, 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.

   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.
   • Dependent on the setting of the Message per Vehicle check box in the Purchase Releases (tdpur3120m000) session, the release is either created per item or per vehicle.
4. The purchase release is printed in the Print Purchase Releases (tdpur3422m000) session.

As a result, the following information is automatically entered in LN when EDI messages are processed:

• 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. If you receive an update of a referenced shipping schedule, LN does not create a new sales schedule revision number. 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. As a result, a sales release position detail refers to a sales schedule line.
• A sales schedule with sales schedule revision number 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 if 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.
