SAP Error Message - Details

• Message type: E = Error

• Message class: STC_CONT_CFG_ENTITY - Technical Configuration Entity Messages

• Message number: 200

• Message text: Parameter &1 has key flag so it also should have direction INOUT.

What causes this issue?

A key parameter is used to select a config entity as input when
executing an operation on an entity. And it is used to describe the
result of an operation.
So it should have the direction INOUT, i.e. Runtime <-> Entity a.k.a.
Changing

System Response

The parameter definition maintenance raises an error.

How to fix this error?

Check the definition. Either change the direction setting or remove the
key flag.

• What is the cause and solution for SAP error message STC_CONT_CFG_ENTITY200 - Parameter &1 has key flag so it also should have direction INOUT. ?

  The SAP error message STC_CONT_CFG_ENTITY200 indicates that there is a configuration issue related to a parameter in a process or function module that is expected to have a specific direction (INOUT) due to its key flag status. This typically occurs in the context of SAP's process integration or when configuring certain types of workflows or background jobs.
  Cause:
  The error arises when a parameter that is marked as a key (i.e., it is essential for identifying a unique record or entity) is not set up correctly in terms of its direction. In SAP, parameters can have different directions:
  
  IN: The parameter is input only.
  OUT: The parameter is output only.
  INOUT: The parameter can be used for both input and output.
  
  If a parameter is marked as a key, it is expected to be able to both receive a value (input) and return a value (output), hence it should be defined as INOUT. If it is incorrectly defined as IN or OUT, the system will raise this error.
  Solution:
  To resolve this error, you need to check the configuration of the parameter in question. Here are the steps to follow:
  
  
  Identify the Parameter: Look at the error message to identify which parameter is causing the issue (the &1 placeholder will be replaced with the actual parameter name).
  
  
  Check Parameter Configuration:
  
  Go to the relevant transaction or configuration area where the parameter is defined (this could be in a function module, a workflow, or a process configuration).
  Verify the properties of the parameter. Ensure that it is marked as INOUT if it is a key parameter.
  
  
  
  Modify the Parameter Direction:
  
  If the parameter is incorrectly set as IN or OUT, change its direction to INOUT.
  Save your changes.
  
  
  
  Test the Configuration: After making the changes, re-run the process or function that was causing the error to ensure that the issue is resolved.
  
  
  Check Documentation: If you are unsure about the implications of changing the parameter direction, refer to the SAP documentation or consult with a colleague who has experience with the specific configuration.
  
  
  Related Information:
  
  SAP Notes: Check SAP Notes for any known issues or additional guidance related to this error message.
  Transaction Codes: Familiarize yourself with relevant transaction codes such as SE80 (Object Navigator), SE37 (Function Module), or SWDD (Workflow Builder) depending on where the error is occurring.
  Debugging: If the issue persists, consider using debugging tools to trace the execution and see how the parameters are being passed and utilized.
  
  By following these steps, you should be able to resolve the STC_CONT_CFG_ENTITY200 error and ensure that your parameter configurations are correct.
