How To Fix UCT8207 - Error during mapping of concatenation component &2 in target field &1

SAP Error Message - Details

• Message type: E = Error

• Message class: UCT8 - Message class for UCT8(mapping)

• Message number: 207

• Message text: Error during mapping of concatenation component &2 in target field &1

What causes this issue?

The mapping rule for target field &V1& contains a move with a
concatenation rule. During method execution, the system discovered that,
after the concatenation component &V2& is inserted, the character string
exceeds the length of the target data. The concatenation rule presumably
contains too many components.
Another cause might be that the format of concatenation component &V2&
is incompatible with the format of the target data. In this case, the
conversion settings are incorrect.

System Response

The system will not execute the mapping rule for target field &V1&.

How to fix this error?

Examine the mapping rule for target field &V1& and change the settings
as follows depending on what caused the error:
In the mapping rule for target field &V1&, reduce the number of
concatenation components or shorten the lengths of the individual con
catenation components.
Select or deselect the <LS>Conversion Exit</> indicator for the
concatenation component &V2& in the mapping rule for target field &V1&.

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 UCT8207 - Error during mapping of concatenation component &2 in target field &1 ?

  The SAP error message UCT8207 indicates that there is an issue during the mapping of a concatenation component in a target field. This error typically occurs in the context of data transformation processes, such as when using the SAP Data Services or SAP BW (Business Warehouse) for data loading or transformation.
  Cause:
  The error can be caused by several factors, including:
  
  
  Incorrect Mapping Configuration: The mapping of the concatenation component to the target field may not be set up correctly. This could involve incorrect data types, incompatible lengths, or missing components.
  
  
  Data Type Mismatch: The source data type may not match the expected data type of the target field. For example, trying to concatenate a string with a numeric field without proper conversion.
  
  
  Null or Empty Values: If one of the components being concatenated is null or empty, it may lead to issues during the mapping process.
  
  
  Field Length Exceeded: The concatenated result may exceed the maximum length allowed for the target field.
  
  
  Transformation Logic Errors: There may be errors in the transformation logic that define how the concatenation should occur.
  
  
  Solution:
  To resolve the UCT8207 error, you can take the following steps:
  
  
  Check Mapping Configuration: Review the mapping configuration for the concatenation component and ensure that all components are correctly mapped to the target field.
  
  
  Verify Data Types: Ensure that the data types of the source fields match the expected data types of the target field. If necessary, use conversion functions to convert data types appropriately.
  
  
  Handle Null Values: Implement logic to handle null or empty values in the source fields. You can use functions to replace nulls with default values or skip concatenation if a component is null.
  
  
  Check Field Lengths: Ensure that the total length of the concatenated result does not exceed the maximum length of the target field. If it does, consider truncating the result or adjusting the target field length if possible.
  
  
  Review Transformation Logic: Double-check the transformation logic for any errors or inconsistencies that could lead to the mapping failure.
  
  
  Test with Sample Data: Run tests with sample data to identify specific cases that trigger the error, which can help in debugging the issue.
  
  
  Related Information:
  
  SAP Documentation: Refer to the official SAP documentation for the specific module you are working with (e.g., SAP BW, SAP Data Services) for detailed information on mapping and transformation processes.
  SAP Community: Engage with the SAP Community forums to see if other users have encountered similar issues and to find additional solutions or workarounds.
  Transaction Codes: Familiarize yourself with relevant transaction codes (e.g., RSA1 for SAP BW) that can help you navigate the data modeling and transformation processes.
  
  By following these steps and considerations, you should be able to diagnose and resolve the UCT8207 error effectively.
