Diagnosis
The process instruction is of type "dynamic function call".
With characteristic &V1& &V2&, an interface parameter of the functionmodule is assigned to the process instruction. Immediately after theparameter, you need to assign the value to be transferred for theparameter or a variable which refers to the value to be transferredwithin the PI sheet.
However, in the process instruction, the value to be transferred is notdefined at this position.

Procedure
Assign the value or variable to the process instruction after thedefinition of the parameter.
