• What is the cause and solution for SAP error message C$723 - Function &: Incorrect table parameter type & (pool) ?

  The SAP error message C$723, which states "Function &: Incorrect table parameter type & (pool)," typically occurs when there is a mismatch in the expected data type of a table parameter in a function module or method. This error is often related to the use of internal tables in ABAP (Advanced Business Application Programming).
  Cause:
  
  Incorrect Data Type: The function module or method is expecting a specific type of internal table (e.g., standard table, sorted table, hashed table), but the parameter being passed does not match this expected type.
  Table Pool Issues: The error may also arise if the internal table is defined in a way that is incompatible with the function module's expectations, particularly if it involves table pools or cluster tables.
  Parameter Mismatch: If the function module is designed to accept a certain structure or type of data, and the calling program passes a different structure or type, this error can occur.
  
  Solution:
  
  Check Function Module Definition: Review the definition of the function module or method to understand the expected data types for the parameters. Ensure that the internal table you are passing matches the expected type.
  Adjust Data Types: If there is a mismatch, adjust the data type of the internal table in your calling program to match the expected type. This may involve changing the definition of the internal table or converting the data before passing it.
  Use Correct Structures: Ensure that the structure of the internal table matches the expected structure in the function module. If necessary, create a new internal table with the correct structure.
  Debugging: Use the ABAP debugger to step through the code and inspect the types of the variables being passed to the function module. This can help identify where the mismatch occurs.
  Documentation: Refer to the SAP documentation for the specific function module to understand its requirements and constraints.
  
  Related Information:
  
  ABAP Data Types: Familiarize yourself with the different types of internal tables in ABAP (standard, sorted, hashed) and their characteristics.
  Function Module Documentation: Always check the documentation for the function module you are using to ensure you are passing the correct parameters.
  SAP Notes: Search for any relevant SAP Notes that might address this specific error or provide additional context or solutions.
  
  By following these steps, you should be able to resolve the C$723 error and ensure that your function calls are correctly parameterized.
