• Message class: P0 - Messages for Transactions PE01, PE02 and PE03

• Message number: 810

• Message text: There are no fixed parameter values if parameter type is not initial

What causes this issue?

You can only assign parameter values if the parameter type has not been
specified. If the parameter type has been specified, it determines the
valid parameters.

• What is the cause and solution for SAP error message P0810 - There are no fixed parameter values if parameter type is not initial ?

  The SAP error message P0810, "There are no fixed parameter values if parameter type is not initial," typically occurs in the context of ABAP programming or when working with function modules, particularly when dealing with parameters in function calls.
  Cause:
  This error usually arises when:
  
  Parameter Type Mismatch: You are trying to call a function module or method that expects certain parameters to be initialized or set, but they are not. Specifically, if a parameter is defined as a fixed parameter (i.e., it should have a specific value), and it is not initialized, this error will occur.
  Incorrect Function Module Call: The function module or method being called may have been defined with certain expectations regarding the parameters, and if those expectations are not met, the error will be triggered.
  Missing or Incorrectly Defined Parameters: If the parameters are not defined correctly in the function module or if the calling program does not provide the necessary values, this error can occur.
  
  Solution:
  To resolve the P0810 error, you can take the following steps:
  
  Check Parameter Definitions: Review the function module or method definition to ensure that all required parameters are correctly defined and initialized before the call.
  Initialize Parameters: Make sure that all parameters that are expected to have values are initialized properly in your code. If a parameter is defined as a fixed parameter, it must have a value assigned before the function call.
  Review Function Module Documentation: Check the documentation for the function module to understand the expected input parameters and their types. Ensure that you are passing the correct types and values.
  Debugging: Use the ABAP debugger to step through the code and inspect the values of the parameters being passed to the function module. This can help identify which parameter is causing the issue.
  Consult SAP Notes: Sometimes, specific issues may be documented in SAP Notes. Check the SAP Support Portal for any relevant notes that might address this error.
  
  Related Information:
  
  Function Module Documentation: Always refer to the documentation of the function module you are using to understand its parameters and expected behavior.
  ABAP Programming Guidelines: Familiarize yourself with best practices in ABAP programming, especially regarding parameter handling and function calls.
  SAP Community: Engage with the SAP Community forums or other user groups where similar issues may have been discussed, and solutions shared.
  
  By following these steps, you should be able to identify the root cause of the P0810 error and implement a solution to resolve it.
