This process instruction is of type "dynamic function call".

interface parameter using characteristic PPPI_IMPORT_PARAMETER or
PPPI_CHANGING_PARAMETER. In order for the system to be able to process
this parameter correctly, you need to assign a variable to it that
identifies the parameter in the process instruction. This variable
must be positioned directly after the characteristic.
The system could not determine a constant value for characteristic &V1&
&V2&.

,,Date,,,,PPPI_DATE_VARIABLE
,,Time,,,,PPPI_TIME_VARIABLE

,,Alphanumeric value,,,,PPPI_STRING_VARIABLE
Assign the following values to the characteristic:
Assign a new variable name after PPPI_IMPORT_PARAMETER for the value
you want to import.
After PPPI_CHANGING_PARAMETER, use the name of an existing variable
whose value you want to transfer to the function module.
The variable must be defined for the same control recipe destination in
the previous process instruction.
