• What is the cause and solution for SAP error message FDT_CORE287 - Length was reduced to &1 compared to &2 in DDIC ?

  The SAP error message FDT_CORE287 indicates that there is a discrepancy in the length of a field defined in the Data Dictionary (DDIC) compared to what is expected in the context of the application or data flow. This typically occurs in scenarios involving field mappings, data transformations, or when working with data models in SAP applications, particularly in the context of SAP Fiori or SAP S/4HANA.
  Cause:
  The error arises when the length of a field in the Data Dictionary is shorter than what is required or expected by the application or the data processing logic. This can happen due to:
  
  Field Length Changes: If the field length in the DDIC has been modified (e.g., reduced) after it was initially defined or used in a data model or mapping.
  Inconsistent Data Models: If there are inconsistencies between the data model definitions in different parts of the application or between the application and the underlying database.
  Data Transformation Logic: If there are transformations or mappings that expect a longer field length than what is defined in the DDIC.
  
  Solution:
  To resolve the FDT_CORE287 error, you can take the following steps:
  
  
  Check Field Definitions: Review the field definitions in the Data Dictionary (transaction SE11) to ensure that the lengths are consistent with what is expected in the application or data model.
  
  
  Adjust Field Lengths: If necessary, adjust the field lengths in the DDIC to match the expected lengths. This may involve changing the data element or structure definition.
  
  
  Review Data Mappings: If you are using data mappings or transformations, ensure that they are correctly configured to handle the field lengths as defined in the DDIC.
  
  
  Test Changes: After making adjustments, test the changes in a development or quality assurance environment to ensure that the error is resolved and that there are no unintended side effects.
  
  
  Consult Documentation: Review any relevant SAP documentation or notes related to the specific application or module you are working with, as there may be specific guidelines or best practices to follow.
  
  
  Seek Support: If the issue persists, consider reaching out to SAP support or consulting with a technical expert who has experience with the specific application or module.
  
  
  Related Information:
  
  Transaction Codes: SE11 (Data Dictionary), SE80 (Object Navigator), SE37 (Function Module), and SE24 (Class Builder) may be useful for checking definitions and mappings.
  SAP Notes: Check for any SAP Notes that may address known issues or provide guidance related to this error message.
  Documentation: Review SAP Help documentation for the specific module or application you are working with for additional context and troubleshooting steps.
