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

LDAPMAP019 - Overview

• 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.

LDAPMAP019 - Details

• 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.
