SAP Error Message - Details

• Message type: E = Error

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

• Message number: 244

• Message text: Variable &1 was declared anew. The old declaration was overwritten

What causes this issue?

Browser-based test PI sheets in which you have declared global
variables and that you have created several times are processed as
follows:
The system always uses the variable value of the PI sheet in which the
variable has <LS>last</> been declared and transfers this value to the
PI sheet in which the variable is to be used.
The system overwrites all variable values of previous PI sheets in
which the variable was declared.
In this case, you have defined global variable &V1& in a browser-based
test PI sheet that you have created several times. The value of
variable &V1& that has last been declared is transferred.

System Response

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

• What is the cause and solution for SAP error message CPOC244 - Variable &1 was declared anew. The old declaration was overwritten ?

  The SAP error message CPOC244 indicates that a variable in your ABAP program or calculation view has been redeclared, which means that the new declaration has overwritten the previous one. This can lead to confusion and potential issues in your code, as the original variable's properties and values may be lost.
  Cause:
  
  Variable Redeclaration: The most common cause of this error is that the same variable name is being declared multiple times within the same scope. This can happen in ABAP programs, function modules, or calculation views.
  Scope Issues: If a variable is declared in a broader scope (like a global variable) and then redeclared in a narrower scope (like a local variable), it can lead to this error.
  Copy-Pasting Code: Sometimes, when code is copied and pasted, the variable names may not be changed, leading to redeclaration.
  
  Solution:
  
  Check Variable Declarations: Review your code to identify where the variable is declared. Ensure that each variable has a unique name within its scope.
  Rename Variables: If you find that a variable is being redeclared, consider renaming one of the variables to avoid the conflict.
  Use Unique Names: Adopt a naming convention that ensures variable names are unique and descriptive, which can help prevent such issues in the future.
  Refactor Code: If the variable needs to be reused, consider refactoring your code to use the existing variable instead of redeclaring it.
  Debugging: Use debugging tools to trace the variable's lifecycle and understand where the redeclaration is occurring.
  
  Related Information:
  
  ABAP Programming Guidelines: Familiarize yourself with best practices in ABAP programming to avoid variable redeclaration issues.
  SAP Documentation: Refer to SAP's official documentation for more details on variable scope and declaration rules.
  Code Review: Regular code reviews can help catch such issues early in the development process.
  
  By following these steps, you should be able to resolve the CPOC244 error and prevent it from occurring in the future.
