How To Fix UCT8208 - Source and target key figures for field &1 have different units of meas.

SAP Error Message - Details

• Message type: E = Error

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

• Message number: 208

• Message text: Source and target key figures for field &1 have different units of meas.

What causes this issue?

The system processes the unit of measure of a key figure during the
conversion from the external format to the SAP-internal format and durin
g the conversion from the SAP-internal format to the external format.
While mapping a source key figure to a target key figure for field &V1&,
the system discovered that the unit for the source key figure (for
example, EUR) is not the same as the unit for the target key figure (for
example, USD). Maybe the move is incorrect or the mapping rules are
missing for the target fields that require units of measure.

System Response

The system will execute the method and convert the source and target key
figures using the defined units of measure.

How to fix this error?

Examine the mapping rule for field &V1& and make sure you really want to
use this move; also make sure that there are proper mapping rules for
the target fields that use units (such as the currency key or units of
measure).

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 UCT8208 - Source and target key figures for field &1 have different units of meas. ?

  The SAP error message UCT8208 indicates that there is a mismatch in the units of measure between the source and target key figures in a data transfer or transformation process. This typically occurs in scenarios involving data extraction, transformation, and loading (ETL) processes, such as in SAP BW (Business Warehouse) or SAP HANA.
  Cause:
  The error arises when:
  
  The source key figure (the data being transferred) has a different unit of measure compared to the target key figure (the destination where the data is being loaded).
  For example, if the source key figure is in kilograms and the target key figure is in grams, the system will raise this error because it cannot automatically convert between these units.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check Key Figure Definitions:
  
  Verify the definitions of both the source and target key figures in the data model. Ensure that they are intended to represent the same type of data.
  
  
  
  Adjust Units of Measure:
  
  If the source and target key figures are supposed to represent the same data but in different units, you may need to adjust the units of measure in the source data or apply a conversion during the data transfer process.
  You can create a transformation rule that includes a conversion factor to align the units.
  
  
  
  Modify Data Flow:
  
  If the mismatch is due to a design issue, consider modifying the data flow or the transformation logic to ensure that the units are consistent.
  
  
  
  Consult Documentation:
  
  Review the documentation for the specific data model or process you are working with to understand the expected units of measure for each key figure.
  
  
  
  Testing:
  
  After making adjustments, perform tests to ensure that the data transfer works correctly without raising the error.
  
  
  
  Related Information:
  
  SAP BW/4HANA: In SAP BW, key figures are often defined in InfoObjects, and you can check the properties of these InfoObjects to see their units of measure.
  Data Transformation: When creating transformations in SAP BW, you can specify conversion routines to handle unit conversions.
  Error Logs: Check the error logs or the process chain logs for additional context on where the error is occurring, which can help in troubleshooting.
  
  By following these steps, you should be able to identify the cause of the UCT8208 error and implement a solution to resolve it.
