Definition
Process instruction types are keys that have been define in Customizing for Process Management and that you must specify when you create a process instruction category. You use the process instruction type to determine which functions are to be supported in the process instruction category. Depending on whether the process instruction category is defined for the PI sheet or a process control system, you must use the corresponding process instruction type.
Use
There are eight different process instruction types. Which type you can use, depends on different criteria.
The type is used to distinguish:
For information processing by process control systems, you can use the following process instruction types:
For examples of process instructions for a process control system, see Process Instruction Structure.

For information processing using the PI sheet, you can use the following process instruction types:
For examples of process instructions for the PI sheet, see
Process Instructions for the R/3 PI Sheet.
