  The SAP error message DT606, which states "Specifications for number of key fields are deleted," typically occurs in the context of data transfer or data modeling, particularly when working with Data Transfer (DT) or Data Warehousing scenarios. This error indicates that the system is unable to find the specifications for the key fields that are required for a particular operation, such as data extraction or loading.
  Cause:
  
  Deleted Specifications: The key field specifications that were previously defined for a data object (like an InfoObject or DataSource) have been deleted or are no longer available in the system.
  Inconsistent Data Model: Changes in the data model, such as modifications to InfoObjects or DataSources, can lead to inconsistencies if the key fields are not properly maintained.

  Check Key Field Specifications: Go to the relevant transaction (like RSA1 for Data Warehousing) and check the specifications for the key fields of the affected object. Ensure that they are correctly defined.
  Recreate Specifications: If the specifications have been deleted, you may need to recreate them. This can involve defining the key fields again in the relevant InfoObject or DataSource.
  Transport Corrections: If the issue arose due to a transport, check the transport logs for errors and ensure that all necessary objects were included in the transport request. You may need to re-transport the missing specifications.
