SAP Error Message - Details

• Message type: E = Error

• Message class: R7 - BW: Data basis

• Message number: 544

• Message text: Characteristic &1 has no conversion routine, ouput length set to &2

What causes this issue?

Characteristic &V1& does not have a conversion routine or has
conversion routine 'ALPHA'. Additionally, the internal length &V2& was
not the same as the output length &V3&.
In this case the internal length and the output length must agree.
Different lengths only make sense for characteristics with conversion
routines not of type 'ALPHA'.

System Response

Output length was set to &V2&.

• What is the cause and solution for SAP error message R7544 - Characteristic &1 has no conversion routine, ouput length set to &2 ?

  The SAP error message R7544 indicates that a characteristic in your SAP system does not have a conversion routine defined, which is necessary for the system to interpret the data correctly. This error typically arises in the context of SAP BW (Business Warehouse) or when dealing with characteristics in InfoObjects.
  Cause:
  
  Missing Conversion Routine: The characteristic specified in the error message does not have an associated conversion routine. Conversion routines are used to convert data from one format to another, and if one is missing, the system cannot process the data correctly.
  Data Type Mismatch: The data type of the characteristic may not match the expected format, leading to issues when the system tries to interpret the data.
  Configuration Issues: There may be configuration issues in the InfoObject or the data model that prevent the conversion routine from being recognized.
  
  Solution:
  
  
  Define a Conversion Routine:
  
  Go to the InfoObject maintenance transaction (e.g., RSD1).
  Find the characteristic that is causing the error.
  Check if a conversion routine is defined. If not, you will need to create one.
  You can create a conversion routine using ABAP code if necessary, or use existing routines if applicable.
  
  
  
  Check Data Types:
  
  Ensure that the data type of the characteristic matches the expected input. If there is a mismatch, you may need to adjust the data type or the incoming data format.
  
  
  
  Review InfoObject Settings:
  
  Check the settings of the InfoObject in the Data Warehousing Workbench. Ensure that all necessary attributes and settings are correctly configured.
  
  
  
  Transport Requests:
  
  If the characteristic was recently transported from another system, ensure that all related objects and routines were included in the transport request.
  
  
  
  Testing:
  
  After making changes, test the data load or query to ensure that the error is resolved.
