Short text

Using Global Variables in PI Sheets and Manufacturing Cockpits (Enhanced)

Use

You can define variables in process management to transfer characteristic values from one process instruction to antother. The system distinguishes between simple and global variables. Until now, the following applied:

• Simple variables could only be transferred within one control recipe or one cockpit.

• Global variables could only be transferred between different control recipes of the same process order. Exchanging variable values between PI sheets and manufacturing cockpits as well as between cockpits was not possible either.

As of SAP R/3 Enterprise SCM Extension 1.10 (EA_APPL 110), you can now use the new Manufacturing Data Access interface to also exchange global variables as follows:

• Between PI sheets of different process orders

• Between PI sheets and cockpits

• Between different cockpits

Global Variable Definition

Global variables are defined as before by assigning characteristic PPPI_GLOBAL_VARIABLE to the process instruction immediately before the message characteristic whose value you want to transfer.

Characteristic	Value Assigned
PPPI_GLOBAL_VARIABLE	Variable name
Message characteristic	Characteristics of the message category assigned

Using Global Variables

To use Manufacturing Data Access to work with global variables, you define the following in the process instruction:

Read Data

Characteristic	Value Assigned
PPPI_DATA_ACCESS	Manufacturing Data Access
PPPI_IMPORT_DATA	Data point or global variable of the application from which the value is to be transferred to the subsequent variable

Example:

PPPI_DATA_ACCESS	Manufacturing Data Access
PPPI_IMPORT_DATA	PMC:1100.MYCOCKPIT.GINVAR
PPPI_STRING_VARIABLE	VAR

Write Data

Characteristic	Value Assigned
PPPI_DATA_ACCESS	Manufacturing Data Access
PPPI_EXPORT_DATA	Data point or global variable of the application into which the value of the subsequent variable is to be transferred
Parameter characteristic	Variable names with the relevant data type

For more information, see Data Exchange Between Applications in the SAP R/3System.

Note that global variables that are transferred using Manufacturing Data Access may only be defined in Process instructions of type 0: universal process instruction category.
