• What is the cause and solution for SAP error message CNV_NCE_BAS144 - NR interval &1: alphanumeric pattern '&2' is not allowed ?

  The SAP error message CNV_NCE_BAS144 typically occurs during data conversion processes, particularly when using the SAP Data Migration tools or during the execution of a conversion program. This error indicates that there is an issue with the format of the data being processed, specifically that an alphanumeric pattern is not allowed for a certain interval.
  Cause:
  The error message can be broken down as follows:
  
  NR interval &1: This indicates that the error is related to a numeric range (NR) interval, where &1 would be the specific interval number.
  Alphanumeric pattern '&2' is not allowed: This part of the message indicates that the data being processed contains an alphanumeric value (represented by &2) that does not conform to the expected numeric format.
  
  Common causes for this error include:
  
  Incorrect Data Format: The data being imported or converted contains characters that are not valid for a numeric field (e.g., letters, special characters).
  Data Mapping Issues: There may be a mismatch in the data mapping configuration, where a field expected to be numeric is being populated with alphanumeric data.
  Configuration Errors: The settings in the conversion program may not be correctly defined, leading to the acceptance of invalid data formats.
  
  Solution:
  To resolve the CNV_NCE_BAS144 error, you can take the following steps:
  
  
  Check the Data Source: Review the source data for the specific interval mentioned in the error message. Ensure that all values intended for numeric fields are indeed numeric and do not contain any letters or special characters.
  
  
  Data Cleansing: If the source data contains invalid entries, you may need to cleanse the data. This can involve:
  
  Removing or replacing invalid characters.
  Ensuring that all entries conform to the expected numeric format.
  
  
  
  Review Mapping Configuration: Check the mapping configuration in the data migration tool to ensure that fields are correctly defined. Make sure that numeric fields are mapped to numeric data types.
  
  
  Adjust Conversion Program Settings: If applicable, review the settings of the conversion program to ensure that it is configured to handle the data correctly. This may involve adjusting validation rules or data type definitions.
  
  
  Testing: After making the necessary changes, re-run the conversion process to see if the error persists. It may be helpful to test with a smaller subset of data to isolate the issue.
