Editing Data Requests in the PI Assistant You want to maintain a process data request for the PI sheet.
You have created the process data request in the master recipe and called the process instruction assistant (PI assistant); see Editing Process Instructions in the PI Assistant .

If you can only define some of the data request data, such as the value of a message characteristic, when you are in the process order, you can leave the relevant field blank in the master recipe. In this case, you can leave the relevant field empty in the master recipe.
On the first screen, check and, if necessary, correct the settings for the type of data request.
Set the indicator for the corresponding data request type.
If you define a repeated data request, enter the minimum and maximum number of lines for the input table if required.
Choose
Next screen
.
On the second screen, check and, if necessary, correct the message category allocation to the data request.
Enter the message category of the process message to be created for the process instruction in the PI sheet.
To help you select the message category, the assistant displays all characteristics of the assigned message category on this screen.
If you define a repeated data request, choose
Insert MessCategory
for every additional message category and enter the message category key.
If you have assigned several message categories, use the sort numbers to specify the message category sequence.
If you define a repeated data request, select the message category whose processing data you want to enter in the next step.
Choose
Next screen
.
On the third screen, check and, if necessary, correct the selection and processing of the message characteristics and variables you want to copy to the process instruction.
Set the selection indicator for the characteristics of the process message category you want to copy to the process instruction, and thus to the corresponding process message.
If you want to add characteristics to the process message that are not defined for the message category, choose
Add. char.
and select the characteristic you want to add.
If you want to display additional variable values in the PI sheet, choose
Output variable
and enter the variable name.
Set the
Input
indicator for characteristics whose values you want to enter in the PI sheet.
Set the
Output
indicator for characteristics whose values are to be displayed in the PI sheet.
For characteristics that are also marked as input values, you can use this indicator to display a planned value deviating from an actual value.
The
Output
indicator is automatically set for variables.
If the unit of measure is to be displayed after a numeric input value, set the
UM
indicator for this input value.
You can only do so if the standard characteristic for the unit of measure is contained in the process instruction and the
Input
indicator is not set for the unit of measure in the process instruction.
Choose
Next screen
On the fourth screen, check and, if necessary, correct the short texts and the sequence of the input and output values.
Use the sort numbers to specify the sequence of the input and output values.
Enter short texts for the input and output values.

If you define several output values in simple data requests and want them displayed in the same line, enter a short text for the first output value only.
If you want to group several values under a common heading in a simple data request, choose
Group
and enter the heading.
Enter the appropriate sort number to specify where the heading is to be displayed.
In the PI sheet, all values following this heading are indented.
Choose

On the fifth screen, check and, if necessary, correct the data on how the message characteristics are to be processed in the PI sheet.
If you enter long texts, note that paragraph and character formats are only taken into account in the browser-based PI sheet but not in the ABAP list-based PI sheet.
For hidden characteristics and output values:
Select the message characteristic and choose
.
In the
Default value
group box, specify value assignment for the characteristic.
If required, enter a variable name for the characteristic value in the
Variable definition
group box and specify the variable’s validity area.
For input values:
Select the message characteristic and choose
.
In the
Default value
group box, specify whether a default value is to be displayed for the input value and how it is determined.
Check and, if necessary, correct the validation rule in the
Input validation
group box.
If you have assigned a check function, choose
and check the data entered for parameter value assignment.

You cannot define an input validation for the standard characteristic
Signature
. Depending on the type of signature defined in the control recipe destination, you enter the following data:
For signatures with a simple password check: details on the authorization check
For digital signaturesdetails on the authorization check, signature strategy and signature process
If you define a numeric input value, enter a variable name for the characteristic value in the
Variable definition
group box if required and specify the variable’s validity area.
If you are maintaining a repeated data request, choose
Next screen.
The system takes you back to the second screen.
Select the next message category and repeat steps 3 to 5.
When you have edited all message categories, check the process instruction and, if necessary, correct errors (see Checking Process Instructions in the PI Assistant ).
When you have finished editing the data, choose
Copy
and save the master recipe.

If you have not corrected all errors when exiting the process instruction assistant, the error log is displayed. To call up the PI assistant again and correct errors, you must, however, first choose
Continue
to get back to the process instruction overview.
