SAP Error Message - Details

• Message type: E = Error

• Message class: C0 - PP-PI: Messages for PI Sheet and Syntax Checker

• Message number: 648

• Message text: Changing parameter & is missing in the function call

What causes this issue?

The function module that has been called up contains changing
parameter &V1&. In the current call, no value is transferred for this
parameter.

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?

RESET N1
INCLUDE 'NA_HA_POS' OBJECT DOKU ID TX LANGUAGE E
Check
whether the definition of the function call in the process order is
complete
<DS:TRAN.COR2>Change process order</>
whether the variable whose value is to be transferred to the
parameter is defined in a preceding process instruction for the same PI
sheet
whether the value for the variable has been maintained in the PI sheet
If the value to be transferred has not been maintained in the PI sheet,
enter this value. Then carry out the function again.
If the function call is incomplete or the variable is not defined for th
PI sheet, you have the following options:
<ZH>In the case of PI sheets with test function:</>
Correct the process instruction in the process order.
Create a new control recipe and maintain the corresponding PI sheet.
<ZH>In the case of productive PI sheets:</>
Errors in the process instruction cannot be corrected for the current PI
sheet.

• What is the cause and solution for SAP error message C0648 - Changing parameter & is missing in the function call ?

  The SAP error message C0648, which states "Changing parameter & is missing in the function call," typically occurs when a function module or method is called without providing a required changing parameter. In SAP ABAP, changing parameters are those that can be modified by the called function and are expected to be passed by reference.
  Cause:
  The error arises when:
  
  A function module or method is defined with a changing parameter, but the calling program does not pass a corresponding variable for that parameter.
  The parameter is either omitted entirely or incorrectly specified in the function call.
  
  Solution:
  To resolve this error, you should:
  
  Check the Function Module/Method Definition: Look at the definition of the function module or method you are calling. Identify the changing parameters and ensure you understand their purpose.
  Modify the Function Call: Ensure that you are passing the required changing parameter in your function call. For example, if the function module is defined as:
  FUNCTION my_function_module.
    CHANGING
      my_param TYPE my_type.
  ENDFUNCTION.
  You should call it like this:
  DATA: my_variable TYPE my_type.
  CALL FUNCTION 'my_function_module'
    CHANGING
      my_param = my_variable.
  
  Check for Typos: Ensure that the parameter names in the function call match those defined in the function module or method exactly, including case sensitivity.
  Review Documentation: If available, refer to the documentation for the function module or method to understand the expected parameters and their usage.
  
  Related Information:
  
  Changing Parameters: In ABAP, changing parameters are used to pass data to a function module or method that can be modified within that function. They are passed by reference, meaning that changes made to the parameter inside the function will affect the variable in the calling program.
  Function Module Documentation: You can access the documentation for a function module by using transaction SE37 (Function Builder) and entering the function module name. This will provide details on the parameters and their types.
  Debugging: If you are unsure which parameter is causing the issue, you can use the ABAP debugger to step through the code and inspect the parameters being passed to the function call.
  
  By following these steps, you should be able to identify and fix the cause of the C0648 error in your SAP ABAP program.
