  SAP Error Message:
  
  VH701 - A key change is not allowed
  
  Cause:
  The error message VH701 occurs when you attempt to change a key field in a master data record or transactional data where the system does not allow modification of the key fields after the record has been created. In SAP, certain fields are designated as key fields (primary keys) that uniquely identify a record. Changing these fields is not permitted because it would affect data integrity and consistency.
  For example, in vehicle master data (which the message code VH701 suggests), you might be trying to change a vehicle identification number or another key attribute that uniquely identifies the vehicle record. Since these fields are used as keys in database tables, changing them is restricted.
  
  Typical Scenarios:
  
  Changing the vehicle identification number (VIN) or chassis number in vehicle master data.
  Modifying key fields in material master, customer master, or other master data records.
  Attempting to change document numbers or other unique identifiers in transactional data.
  
  
  Solution:
  
  
  Do not change key fields directly:
  
  Instead of changing the key field, create a new record with the correct key data and, if necessary, transfer or copy the relevant data from the old record.
  
  
  Use appropriate transactions or tools:
  
  If you need to correct data related to a key field, check if SAP provides a specific transaction or program for data correction or data migration.
  
  
  Consult business process:
  
  Sometimes, the business process requires cancellation or reversal of the existing record and creation of a new one rather than changing the key.
  
  
  Check customizing or configuration:
  
  In some cases, the system behavior can be influenced by configuration settings. However, changing key field behavior is generally not recommended.
  
  
  If a key change is absolutely necessary:  
  
  Export the data.
  Delete the old record (if allowed).
  Create a new record with the correct key.
  Re-import or re-enter related data.
  
  
  
  
  Related Information:
  
  Key fields in SAP: Fields that uniquely identify a record in a table. They are part of the primary key in database tables.

  Summary:
  
  Cause: Attempt to change a key field in a record where key changes are not allowed.
  Solution: Create a new record with the correct key instead of changing the existing key field.
  Additional: Always ensure data consistency and follow business processes for data correction.
