How To Fix LDAPMAP019 - Mapping does not contain any object classes

SAP Error Message - Details

• Message type: E = Error

• Message class: LDAPMAP - Messages for Mapping and Mapping Maintenance

• Message number: 019

• Message text: Mapping does not contain any object classes

What causes this issue?

You must record the object classes in the "Object Classes" table for
which an entry in the directory is to be synchronized with the
SAP system.
If the system creates a new entry in the directory, the new entry is
assigned this object class.
If the system searches for an entry in the directory, only entries
which have all object classes entered here are found.
Although it is possible to enter an asterisk ("*") as the object class,
we recommend that you do not do so, since this will lead to errors
when creating new entries.

System Response

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

• What is the cause and solution for SAP error message LDAPMAP019 - Mapping does not contain any object classes ?

  The SAP error message LDAPMAP019: Mapping does not contain any object classes typically occurs in the context of integrating SAP systems with LDAP (Lightweight Directory Access Protocol) directories. This error indicates that the mapping configuration for LDAP does not specify any object classes, which are essential for defining the structure of the data being synchronized or accessed.
  Cause:
  
  Missing Object Classes: The mapping configuration for the LDAP integration does not include any object classes. Object classes define the types of entries that can be stored in the LDAP directory (e.g., user, group).
  Incorrect Configuration: The LDAP mapping configuration may be incomplete or incorrectly set up, leading to the absence of necessary object classes.
  Changes in LDAP Schema: If there have been changes in the LDAP schema or if the schema does not match the expected configuration in SAP, this error may arise.
  
  Solution:
  
  
  Check Mapping Configuration:
  
  Go to the SAP system where the LDAP mapping is configured.
  Navigate to the LDAP mapping settings (usually found in transaction codes like LDAPMAP or similar).
  Ensure that the mapping includes the necessary object classes. You should define the object classes that are relevant to your integration (e.g., inetOrgPerson, organizationalUnit, etc.).
  
  
  
  Add Object Classes:
  
  If the object classes are missing, add them to the mapping configuration. This may involve editing the mapping file or using the SAP GUI to update the settings.
  Make sure to include all required attributes for the object classes you are using.
  
  
  
  Validate LDAP Schema:
  
  Check the LDAP directory schema to ensure that the object classes you are trying to map exist and are correctly defined.
  If there are discrepancies, you may need to update the LDAP schema or adjust your SAP mapping accordingly.
  
  
  
  Test the Configuration:
  
  After making changes, test the LDAP connection and mapping to ensure that the error is resolved.
  Use tools like LDAP browsers to verify that the entries are being correctly mapped and synchronized.
  
  
  
  Consult Documentation:
  
  Refer to SAP documentation or guides specific to LDAP integration for detailed instructions on configuring object classes and mappings.
  
  
  
  Related Information:
  
  SAP Notes: Check SAP Notes related to LDAP integration for any known issues or additional guidance.
  LDAP Documentation: Review LDAP documentation for information on object classes and attributes.
  Support: If the issue persists after checking the configuration, consider reaching out to SAP support for further assistance.
  
  By ensuring that the mapping configuration includes the necessary object classes and validating the LDAP schema, you should be able to resolve the LDAPMAP019 error.
