Hi,
Go to NACE and check the access sequence assigned to the output type. Go to Access sequence button in NACE. Now check the condition tables assigned to the access sequence. Ideally all the condition tables defined here will be displayed in MN04 as key combination for the output type. Please check and revert back.
Now, you can check the issue with condition table description. Note the condition table / tables assigned in the access sequence in NACE. Now, check the condition table description in M/61 transaction.
In your case, I think the condition table was created with another user ID where the logon language is different / maintained with a different logon language. If you are able to see the condition table description in your login in M/61, the same will be visible in MN04 as well. If its not visible in M/61 with your login language, then maintain the same in change mode (in M/61) and test the scenario again.
Regards,
AKPT.
