How To Fix CPOC132 - You may use constants for export parameters only

CPOC132 - Overview

• Message type: E = Error

• Message class: CPOC - PP-PI-PMA: Process Operator Cockpit Messages

• Message number: 132

• Message text: You may use constants for export parameters only

What causes this issue?

The following characteristics are used to assign the interface
parameters of the function module to be called to the process
instruction. Directly after each parameter, you must define the value
that is passed on for this parameter. This value must be passed on as a
constant value, a variable, or a message characteristic. The parameter
type determines which of these is used to pass on the value.
For export parameters:
Constant values
Variables
Message characteristics
For import parameters, table parameters, and changing parameters:
Variables
You have, however, attempted to assign a constant value to an import
parameter, table parameter, or changing parameter in the process
instruction. This is not permitted.

System Response

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

How to fix this error?

Assign a variable that stands for the value to be passed on in the PI
sheet to the import parameter, table parameter, or changing parameter.
<DS:TX.NA_INST_VAR>Define Variable</>
<DS:TX.NA_INST_FUPAR_VALV>Assign Variable to Parameter</>

• What is the cause and solution for SAP error message CPOC132 - You may use constants for export parameters only ?

  The SAP error message CPOC132, which states "You may use constants for export parameters only," typically occurs in the context of ABAP programming, particularly when dealing with function modules or methods that have export parameters. This error indicates that you are trying to use a variable or a non-constant expression where a constant is expected for an export parameter.
  
  Cause:
  The error arises when:
  
  You are passing a variable instead of a constant to an export parameter of a function module or method.
  The function module or method is defined in such a way that it expects a constant value for its export parameters.
  
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check the Function Module/Method Definition: Review the definition of the function module or method you are calling. Look at the export parameters and see which ones are defined to accept only constants.
  
  
  Use Constants: If the export parameter requires a constant, ensure that
