SAP Error Message - Details

• Message type: E = Error

• Message class: CNV_OT_APPL_PE - Messages for application specific functions

• Message number: 045

• Message text: Value preparation to screen format for field &1 with value &2 failed

What causes this issue?

Prior to calling the function POSTING_INTERFACE_DOCUMENT within function
module CNV_PE_POST_FI_RFBIBL all incoming data is moved in an internal
table FTPOST of type FTPOST.
Each record of FTPOST represents one screen field of transaction &V3&
with its value.
The value itself must be present in the format that is expected on the
respective screen field. Therefore (within CNV_PE_POST_FI_RFBIBL) each
value is prepared to match the screen input format.
This preparation failed for field &V1& with value &V2&. Instead the
value is passed unchanged into POSTING_INTERFACE_DOCUMENT function
module.

  The SAP error message CNV_OT_APPL_PE045 indicates that there was a failure in preparing a value for display on the screen for a specific field. This error typically occurs during data migration or conversion processes, particularly when using the SAP Landscape Transformation (SLT) or other data migration tools.
  Cause:
  The error can be caused by several factors, including:
  
  
  Data Format Issues: The value being processed does not conform to the expected format for the field. For example, if a numeric field is expecting a number but receives a string or an incorrectly formatted number, this error may occur.
  
  
  Data Type Mismatch: The data type of the value being processed does not match the data type defined for the field in the target system.
  
  
  Invalid Characters: The value may contain invalid characters that are not allowed in the target field.
  
  
  Length Exceedance: The value may exceed the maximum length defined for the field.
  
  
  Configuration Issues: There may be issues with the configuration of the data migration tool or the mapping of fields between source and target systems.
  
  
  Solution:
  To resolve the error, you can take the following steps:
  
  
  Check Data Format: Review the data being processed for the specific field and ensure it matches the expected format. For example, if the field expects a date, ensure the date is in the correct format (e.g., YYYY-MM-DD).
  
  
  Validate Data Types: Ensure that the data types of the source values match the target field definitions. If necessary, convert the data types before migration.
  
  
  Clean Data: Remove any invalid characters from the data. This may involve using data cleansing techniques or scripts to sanitize the data before migration.
  
  
  Check Field Lengths: Verify that the values do not exceed the maximum length defined for the target fields. If they do, truncate or adjust the values accordingly.
  
  
  Review Configuration: Check the configuration of the data migration tool and ensure that the field mappings are correctly defined. Make sure that the source fields are correctly mapped to the target fields.
  
  
  Debugging: If the issue persists, consider enabling debugging or logging in the migration tool to get more detailed information about the error.
