• What is the cause and solution for SAP error message FDT_CORE288 - Number of decimals was reduced to &1 compared to &2 in DDIC ?

  The SAP error message FDT_CORE288 indicates that there is a discrepancy in the number of decimal places defined for a field in the Data Dictionary (DDIC) compared to what is expected in the context of the application or data processing. Specifically, it means that the number of decimal places for a certain field has been reduced from a higher value to a lower one.
  Cause:
  
  Data Dictionary Definition: The field in the Data Dictionary (DDIC) has a defined number of decimal places that is greater than what is being used in the application or data processing context.
  Field Mapping Issues: When mapping fields between different data sources or structures, the number of decimal places may not match, leading to this error.
  Data Type Changes: If the data type of a field has been changed (e.g., from a decimal with more places to one with fewer), this can trigger the error.
  Configuration Changes: Changes in configuration settings or updates to the system that affect how fields are interpreted can also lead to this issue.
  
  Solution:
  
  Check Data Dictionary Settings: Review the field definitions in the Data Dictionary (transaction SE11) to ensure that the number of decimal places is set correctly according to the business requirements.
  Adjust Field Mapping: If the error occurs during data transfer or mapping, ensure that the source and target fields have compatible definitions regarding decimal places.
  Review Application Logic: If the application logic is enforcing a specific number of decimal places, ensure that it aligns with the DDIC definition.
  Data Type Consistency: Ensure that the data types used in the application and the DDIC are consistent and appropriate for the data being processed.
  Testing: After making changes, conduct thorough testing to ensure that the issue is resolved and that no new issues arise from the changes.
  
  Related Information:
