How To Fix MC199 - All physical matchcode IDs are case-sensitive

SAP Error Message - Details

• Message type: E = Error

• Message class: MC - Aggregate: views, matchcodes, lock objects

• Message number: 199

• Message text: All physical matchcode IDs are case-sensitive

What causes this issue?

Only transparent matchcode IDs (update type 'I') exist for the
matchcode object. These are implemented with views. The SAPMACO
therefore need not construct any matchcode records in this case.

System Response

Processing is terminated if exactly one matchcode object is to be
maintained. If a like pattern is entered for the matchcode object, i.e.
if several matchcode objects are to be maintained, the next matchcode
object is maintained.

How to fix this error?

The database views must be created for the transparent matchcode IDs. If
they were not yet created, they must be created with transaction SE11.
The SAPMACO should not be called for matchcode objects which only
contain tranparent matchcode IDs since such transparent IDs are
implemented directly with a database view. This ensures data access
without calling SAPMACO.

• What is the cause and solution for SAP error message MC199 - All physical matchcode IDs are case-sensitive ?

  The SAP error message MC199, which states "All physical matchcode IDs are case-sensitive," typically occurs when there is an issue with the matchcode IDs being used in a query or transaction. Matchcodes in SAP are used to facilitate searches for data, and they can be defined in a case-sensitive manner.
  Cause:
  The error is usually caused by one of the following reasons:
  
  Case Sensitivity: The matchcode IDs being referenced in the transaction or query do not match the case of the IDs defined in the system. For example, if the matchcode ID is defined as "ID1" and you are trying to access it as "id1", the system will not recognize it due to case sensitivity.
  Incorrect Matchcode ID: The matchcode ID you are trying to use may not exist or may have been incorrectly entered.
  Configuration Issues: There may be issues with the configuration of matchcodes in the system.
  
  Solution:
  To resolve the MC199 error, you can take the following steps:
  
  
  Check Matchcode ID: Verify the matchcode ID you are using. Ensure that it matches exactly (including case) with the defined matchcode IDs in the system.
  
  
  Use Correct Case: If you find that the case is incorrect, adjust it to match the defined matchcode ID. For example, if the ID is "ID1", make sure you are using "ID1" and not "id1".
  
  
  Review Configuration: If you are unsure about the matchcode IDs available, you can check the configuration of matchcodes in the SAP system. This can typically be done through transaction codes like SE11 (Data Dictionary) or SE78 (for matchcode objects).
  
  
  Consult Documentation: If you are still having trouble, refer to SAP documentation or consult with your SAP Basis or technical team for further assistance.
  
  
  Testing: After making the necessary adjustments, test the transaction or query again to see if the error persists.
  
  
  Related Information:
  
  Matchcode Objects: Matchcodes are defined in the Data Dictionary and can be created or modified using transaction SE11.
  Case Sensitivity in SAP: SAP is generally case-sensitive for many identifiers, including matchcode IDs, user IDs, and other key fields.
  SAP Notes: Check SAP Notes for any specific patches or updates related to matchcode issues or the MC199 error.
  
  By following these steps, you should be able to resolve the MC199 error and successfully use the matchcode IDs in your SAP transactions.
