XStep process instructions for destination type PI Sheet are displayed as browser-based PI sheets in the SAP system. The process operator can process the PI sheet interactively. That is, the process operator is provided with the instructions for his work at the production line and he then enters data into the system accordingly, which is then further processed in the SAP system.
In order to create process instructions for an XStep, you must first assign a destination type to the XStep or a specific control recipe destination.
Using XStep process instructions you can store the following contents and functions in the PI sheet:
You can output information such as long texts, numerical values and images in the PI sheet.
For more information, see XStep: Outputs.
Using the input fields, you can request production-relevant data, that the process operator should create in the PI sheet. For example, values and signatures can be created in the PI sheet.
For more information, see XStep: Inputs.
Depending upon the data type, you can also define the following functions for input fields:
¡ Suggested Value
¡ Input Validation
¡ Error Handling
· Control Functions
Using control functions you can, for example, create backflushes, carry out calculations and so on. You can store the following functions in the PI sheet:
See: XStep Calculations
¡ Manufacturing Data Access
¡ Automatic Entries
¡ Function Calls
¡ Process Messages
See: Process Messages
A value is suggested, as standard, for the majority of XStep process instructions, which determines the data format of the value. If you want to use a different format, you have to choose a different characteristic from the input help, or create a new characteristic.
You can create your own characteristics in Customizing for production planning – process industries under Process Instructions ® Process Instruction Characteristics ® Define Characteristics for Process Instructions.
The SAP standard layout is defined in such a way that all input and output fields, with the exception of long texts, are displayed on the right side of the PI sheet. If you have defined input and output fields as well as long texts, the long text will be displayed on the left of the PI sheet. In parallel, the input and output fields will also be displayed at the same level.
If you want to change the standard layout of the PI sheet, or you want to define it yourself, you must choose characteristic PPPI_LAYOUT, as is the case with characteristic-based process instructions. To do this, proceed in the following way:
1. Double-click node and choose the tab page Characteristics.
2. Create the characteristic PPPI_LAYOUT in the characteristic overview. It must be in first position in the characteristics list.
3. Go to the Long Text Editor and create your XML definition.
For more information, see Layout Definition for PI Sheets and Cockpits.
The following example illustrates how you can create an XStep process instruction:
Select a new XStep
node and choose Create ® Process Instruction.
The system creates the entry <Process Instructions> underneath the selected XStep node.
Select <New Process Instruction>
and choose Create ® Output ® Long Text.
Under the <New Process Instructions> node, the system creates the entry <Group> with the sub node <Long Text>.
<Long Text> icon.
The Values Output dialog box appears.
4. In the dialog box Value Output enter a description and a long text.
