Diagnosis
The process instruction is of type "dynamic function call".
The following characteristics are used to assign the interfaceparameters of the calling function module to the process instruction:

• PPPI_EXPORT_PARAMETER


• PPPI_CHANGING_PARAMETER


• PPPI_IMPORT_PARAMETER

For the system to be able to process this parameter correctly, you mustdefine the value to be transferred for this parameter or the variableused in the PI sheet for the value to be transferred immediately afterthis parameter.
However, the value to be transferred or the variable is missing for atleast one parameter in the process instruction.

• For export parameters:

Define a constant value or a variable whose value is to be transferredto the function module.

• For import and changing parameters:

Assign the variable defined in the PI sheet for the value to betransferred.
For changing parameters, the variable must have been defined in apreceding process instruction for the same control recipe destinationor PI sheet.
