 Manual Maintenance of Characteristic-Based Process Instructions Locate this document in the navigation structure

Use

Using this function, you create characteristic-based process instructions manually in the process instruction overview if they contain process-specific data that cannot be transferred to the process instruction automatically.

Example Example

The measurement readings to be recorded when a process order is executed vary from process to process. Since no information on this is maintained elsewhere in the process order, you must create the process instructions for the relevant phase manually.

End of the example.

Prerequisites

The following settings have been made in Customizing for Process Management :

  • Process instruction categories, in which the function and contents of your process instructions (that is, the process instruction type and characteristics) are maintained as default.

  • An appropriate value assignment function or table field has been allocated to those process instruction characteristics whose value is to be assigned automatically when you create the control recipe.

Features

You can use the following functions to maintain characteristic-based process instructions in the master recipe or process order:

  • Maintenance Using the Characteristic Overview

    Using this function, you can maintain all characteristic-based process instructions . On the characteristic overview, you can:

    • – Delete and add characteristics

    • – Enter and change characteristic values

      The characteristic structure required for your process instructions depends on the requirements of your process control systems or PI sheet. For more information about the structure of process instructions, see Characteristic-Based Process Instruction Structure .

      A value can be assigned automatically to some characteristics when you create the control recipe. A special indicator is set for these characteristics on the characteristic overview. For more information, see Automatic Value Assignment to Process Instruction Characteristics .

  • Maintaining Process Instructions Using the PI Assistant

    Using this function, you can maintain process instructions for PI sheets .

    The PI assistant offers specific selection screens and prompts for every process instruction type, guiding you through process instruction definition.

    You enter the contents in the process instruction assistant. No knowledge of the process instruction characteristics or their use is required. The system creates the characteristic structure of the process instruction when you exit the assistant.

    Caution Caution

    Note that at present you cannot use the process instruction assistant to define process instructions of Type 0: Universal process instruction category .

    End of the caution.
