 PARAMETER_CHANGED Event Locate this document in the navigation structure

When using XSteps, you can specify that a function module is executed via the event PARAMETER_CHANGED only if values have been assigned to certain parameters in the browser-based PI sheet.

You can specify which parameters must have values assigned to them in order for a function module to be executed. These parameters must be assigned to a characteristic with the Entry Required indicator.

Note Note

On no account should you change the characteristics once the master data has been set up. If you set the Entry Required indicator for a characteristic, you should not change an existing characteristic but create a new one and use the new characteristic.

End of the note.
