  CTP with Block Planning (Example for Finite Scheduling)

Purpose

You can use CTP with block planning .The planned orders created in the CTP process are scheduled in suitable blocks. The advantage of block planning is that resource capacities can be reserved in advance by products that have certain characteristics.

The system uses the results of this scheduling to calculate a confirmation date. Here, the system takes account of the available capacity and, if necessary, component availability.

Using CTP with block planning, you can schedule the orders in one block with as few gaps as possible. More efficient use can be made of the resource’s capacity by assigning the orders to suitable blocks.Every newly received customer requirement is covered immediately and can be confirmed either per day or per block at order entry.

You can use this form of the CTP process for configured sales orders (make-to-order production).However, you can also use the scenario for some standard products that are planned using make-to-stock (planning with final assembly).

In this scenario, it is best to schedule only one level (the final assembly) finitely.

Prerequisites

  • You have activated the use of CDP characteristics by choosing Start of the navigation path Basic Settings Next navigation step Define Class System End of the navigation path in Customizing for SAP APO.

  • You have maintained characteristics and classes in R/3 and transferred them to APO.

  • You have made the settings for the CTP process.

Process

  1. You manually define blocks on the most important resources. You should do this several weeks in advance. See also: Block Maintenance

  2. As soon as you create a new sales order, the system accesses the CTP check. If the SAP APO System determines that the desired product is not available, it creates a new planned order. This planned order is scheduled finitely in a suitable block using the strategy Find Gap .

  3. To fill the capacity gaps in the blocks on the resources as far as possible, you can create requirements for a few standard products that are produced to stock. You do this as late as possible.

  4. Then you can manually move and firm the orders in the blocks as necessary.
