Process Message

DefinitionCommunication structure that is used to transfer actual process data from

process control to one or several destinations of the following types:

Other R/3 components User-defined ABAP tables

Users of the SAP-office mail system

External function modules

The information contained in a process message is determined by the

message characteristics as well as the characteristic values assignedto them.

A characteristic in a characteristics group that has been released foruse in process messages. Process message characteristics areassigned to process message categories. Together with thecorresponding characteristic values, they determine the content of aprocess message.

Process Instructions

UseIn process instructions, you can use predefined characteristics to define

process steps that you want:

To be executed manually by a process operator at a production line To be executed automatically by a process control system

You assign process instructions to the phases of the master recipe andprocess order.

Prerequisites Process instructions that you assign to a phase in the master recipe and

process order must be assigned to a certain process instruction category.You must first have created these process instruction categories inCustomizing for Process Management. They serve as a kind of templatefor the process instruction you use in the master recipe and processorder.

Every process instruction category you create in Customizing must itself

be assigned to a process instruction type.

31/47

Process Instruction Category

Definition:

Process instruction categories are standard process

instructions that have been predefined in Customizing for

Process Managementand that usually do not have specific

characteristic values assigned. They serve as a kind of

template for the process instruction you use in the masterrecipe and process order.

8/11/2019 PP PI.2.ppt

32/47

Process Instruction Type

Definition:

Process instruction types are keys that have been define inCustomizing for Process Managementand that you mustspecify when you create a process instruction category.

You use the process instruction type to determine whichfunctions are to be supported in the process instructioncategory. Depending on whether the process instructioncategory is defined for the PI sheet or a process controlsystem, you must use the corresponding processinstruction type.

Type 1: Process Parameters for PI

Sheets

Use

You can define the following information in a process parameterby assigning characteristics:

Control information displayed on the overview screen of the PIsheet

Additional notes displayed in the PI sheet on one or more detailscreens

The individual elements are displayed in the PI sheet in the

following sequence: All long texts according to their sort numbers

All other control information according to sort number

Pushbuttons for calling up the notes

Type 2: Process Data Request

Process instruction that specifies that processcontrol is to send a process message with actual

process data to the SAP System.

A process data request contains the followinginformation:

Process message category to use for the process message Information to provide by process control

36/47

Type 4: Process Data Calculation

Formula

A type of process instruction that specifies that avalue must be calculated in the PI sheet.

This value is then sent to a destination using aprocess message.

The process data calculation formula specifies: Value to calculate Formula to use for calculation

Message category of the requested process message

Type 5: Inspection Result Request

Process instruction that specifies the operations

and phases for which inspection results must be

recorded. For these operations and phases, thefunction for recording inspection results can be

accessed directly from the PI sheet.

This function can only be used if there is aninspection lot and appropriate characteristics for

the process order.

Type 6: Dynamic Function Calls

Use:

You can use this function to call certain R/3 functions whilemaintaining the PI sheet. Function modules created for the R/3

functions to be called are used to realize the function call.

Prerequisites:

The function module to be called must be defined in the FunctionBuilder and must be active.

For details on the individual function modules, see thecorresponding section below.

Calling of any Transaction

Accessing of Order Confirmation

Displaying of Material Quantity Calculation

Displaying of Documents From Document Management System

Calculation of Time Intervals and Dates
