• What is the cause and solution for SAP error message UCI2053 - Field &1 not contained in the source data basis ?

  The SAP error message UCI2053, which states "Field &1 not contained in the source data basis," typically occurs in the context of data extraction or data processing within SAP systems, particularly when working with data sources in SAP BW (Business Warehouse) or similar environments.
  Cause:
  This error generally indicates that the field specified (represented by &1) is not present in the source data that is being processed. This can happen for several reasons:
  
  Field Mismatch: The field may not exist in the underlying data source (e.g., a database table or a data extraction source).
  Incorrect Data Source: The data source being used may not be the correct one, or it may not have been properly configured to include the required fields.
  Changes in Data Structure: If there have been recent changes to the data structure (e.g., fields added or removed), the data source may not have been updated accordingly.
  Data Extraction Issues: There may be issues with the data extraction process that prevent the field from being included in the data set.
  
  Solution:
  To resolve the UCI2053 error, you can take the following steps:
  
  
  Check Data Source Configuration:
  
  Verify that the data source is correctly configured and that it includes the field in question. You can do this by checking the data source definition in the SAP BW system.
  
  
  
  Validate Field Existence:
  
  Ensure that the field exists in the underlying data source (e.g., the database table). You can do this by querying the database directly or using transaction codes like SE11 (Data Dictionary) to check the structure of the table.
  
  
  
  Update Data Source:
  
  If the field has been added to the source data after the data source was created, you may need to update the data source in SAP BW. This can involve reactivating the data source or making adjustments in the data flow.
  
  
  
  Check for Changes:
  
  If there have been recent changes to the data model or data structure, ensure that all related objects (like InfoObjects, DataSources, etc.) are updated accordingly.
  
  
  
  Review Extraction Logic:
  
  If you are using custom extraction logic (e.g., ABAP code), review the logic to ensure that it correctly handles the fields being extracted.
  
  
  
  Consult Documentation:
  
  Refer to SAP documentation or notes related to the specific data source or error message for additional guidance.
  
  
  
  Related Information:

  SAP Notes: Check SAP Notes for any known issues or patches related to the specific data source or error message.
  SAP Community: Engage with the SAP Community forums for insights from other users who may have encountered similar issues.
