How To Fix LDAPMAP026 - No mapping defined for this filter

SAP Error Message - Details

• Message type: E = Error

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

• Message number: 026

• Message text: No mapping defined for this filter

What causes this issue?

The "Filter" indicator must be set for exactly one attribute in a
mapping.
This attribute is used when reading objects from the directory to
be able to assign the directory entry to an etnry in the SAP system.
For example, in the proposals delivered by SAP for the mapping for
user master synchronization, the attribute "sapUsername" is the
filter attribute, since it is mapped to the database field that contains
the SAP user name..
You must set this indicator, even if you do not want to import any
data from the directory, since the filter attribute is also required
for constructing the search query for the existence check for entries
in the directory.
