Diagnosis
In the process instruction, characteristic PPPI-TEXT_FOR_INVALID_INPUTdefines a warning note for an input validation. You must define thecorresponding checking rule directly in front of the warning note usingcharacteristic PPPI_VALIDATION_FORMULA.
However, the checking rule has not been defined at this point in theprocess instruction.

Procedure
RESET N1
Check whether the checking rule the warning note belongs to exists inthe process instruction.
If the checking rule exists, move characteristicPPPI_TEXT_FOR_INVALID_INPUT to the position directly in front of it.
To do so, change the sort numbers of the characteristics.
If the checking rule does not exist in the process instruction, proceedas follows:
RESET N2
Assign characteristic PPPI_VALIDATION_FORMULA to the processinstruction immediately before characteristicPPPI_TEXT_FOR_INVALID_INPUT.
Assign the required checking rule to the characteristic.

Note
If the checking rule is very long, you can repeatedly assigncharacteristic PPPI_VALIDATION_FORMULA to it. The value to be assignedto the characteristic is the appropriate section of the checking rule.If you do so, you must assign the warning note behind the last formulasection.
