• What is the cause and solution for SAP error message C0823 - Only use function modules without table parameters ?

  The SAP error message C0823, which states "Only use function modules without table parameters," typically occurs when you are trying to use a function module that has table parameters in a context where it is not allowed. This is often seen in scenarios involving remote function calls (RFC) or when using certain types of function modules in specific environments, such as in ABAP programs or when integrating with other systems.
  Cause:
  
  Table Parameters: The function module you are trying to call has one or more table parameters. In certain contexts, such as RFC calls, table parameters are not supported.
  Context Restrictions: The environment or context in which you are trying to use the function module may not support table parameters. For example, if you are calling a function module from a web service or a specific interface that does not allow table parameters.
  
  Solution:
  
  Use Function Modules without Table Parameters: Look for an alternative function module that does not use table parameters. You may need to create a wrapper function module that converts table parameters into single value parameters if necessary.
  Modify the Function Module: If you have control over the function module, consider modifying it to remove table parameters or to handle them differently (e.g., using single value parameters).
  Check Documentation: Review the SAP documentation for the specific function module to understand its parameters and any restrictions on its use.
  Use Structures Instead: If you need to pass multiple values, consider using structures instead of tables, as structures can often be used in contexts where tables cannot.
  Consult SAP Notes: Check for any relevant SAP Notes that might address this issue or provide guidance on how to handle function modules with table parameters.
  
  Related Information:
  
  RFC Function Modules: When working with RFC, it is important to understand the limitations regarding parameters. RFC function modules should ideally use simple data types or structures.
  ABAP Development: If you are developing in ABAP, familiarize yourself with the best practices for creating and using function modules, especially in terms of parameter types.
  SAP Community: Engage with the SAP Community or forums to see if others have encountered similar issues and what solutions they have found.
  
  By addressing the use of table parameters and ensuring that you are using compatible function modules, you should be able to resolve the C0823 error.
