How To Fix SCDT_MAP024 - The table(s) cannot be assigned 1:1

SAP Error Message - Details

• Message type: E = Error

• Message class: SCDT_MAP - Mapping Information for Synchronization

• Message number: 024

• Message text: The table(s) cannot be assigned 1:1

What causes this issue?

You have selected mapping type 'No Mapping Required' for your
synchronization object, but the tables of your synchronization object
cannot be assigned 1:1 because:
there are additional fields in the source or target component table
the source and target component tables use different field names.

System Response

If you keep the mapping type 'No Mapping Required', the Customizing
Scout (transaction SCDT_MON) and the Customizing Synchronizer
(transaction SCDT) only assign the fields which are in both the target
and source component tables and have the same field names. This means
that:
the Customizing Scout ignores all other fields and all fields which
have different field names in the source and target component tables,
for a comparison
the Customizing Synchronizer synchronizes the customizing settings only
in the fields which have the same field names in the source and target
component tables.

How to fix this error?

If you want the Customizing Scout and Customizing Synchronizer to
process fields with different field names for your synchronization
object, choose another mapping type (Mapping with Different Table/Field
Names).

Procedure for System Administrators

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 SCDT_MAP024 - The table(s) cannot be assigned 1:1 ?

  The SAP error message SCDT_MAP024 indicates that there is an issue with the mapping of tables in the context of SAP Data Transfer (SCDT). Specifically, it means that the system cannot assign the specified tables in a one-to-one relationship, which is often required for certain data transfer processes.
  Cause:
  The error typically arises due to one of the following reasons:
  
  
  Inconsistent Data Structure: The source and target tables may have different structures or cardinalities, meaning that the data in the source table does not match the expected format or number of records in the target table.
  
  
  Mapping Configuration Issues: There may be a misconfiguration in the mapping settings where the relationships between the source and target tables are not correctly defined.
  
  
  Duplicate Records: If the source table contains duplicate records that cannot be uniquely mapped to the target table, this can lead to a failure in establishing a one-to-one relationship.
  
  
  Data Type Mismatches: The data types of the fields in the source and target tables may not be compatible, which can prevent proper mapping.
  
  
  Solution:
  To resolve the SCDT_MAP024 error, you can take the following steps:
  
  
  Check Table Structures: Verify that the structures of the source and target tables are compatible. Ensure that the fields you are trying to map have the same data types and that the cardinality is appropriate.
  
  
  Review Mapping Configuration: Go through the mapping configuration in the Data Transfer process. Ensure that the relationships between the tables are correctly defined and that you are not trying to map multiple records from the source to a single record in the target.
  
  
  Eliminate Duplicates: If the source table has duplicate records, consider how to handle them. You may need to aggregate the data or filter out duplicates to ensure a one-to-one mapping.
  
  
  Data Validation: Perform data validation on both the source and target tables to ensure that the data adheres to the expected formats and constraints.
  
  
  Consult Documentation: Refer to SAP documentation or help resources for specific guidelines on mapping tables in your version of SAP, as there may be version-specific considerations.
  
  
  Testing: After making adjustments, test the mapping again to see if the error persists. It may be helpful to run smaller test cases to isolate the issue.
