• Message number: 017

• Message text: Generation of object &1: Object already exists

What causes this issue?

Depending on the <DS:TX.CNV_PE_TX_GEN_MODE>generation mode</>, existing
objects may not be overwritten but remain unchanged.

System Response

This object was generated with generation mode &V2&.
In case this messages occurs in the context of the function group
generation, the meaning is that the function group is not deleted, as
this would also delete all function modules within the function group.
This might be unwanted in certain situations.
<ZH>Note</>
Independent of the generation mode, in case an object is generated the
very first time, the program checks if the object (name) is not yet
available in the system where the object shall be generated/created. In
case an object with the same name already exists, the generation process
will stop and nothing will be deleted or generated.

How to fix this error?

Consider the statements above.
In case of the generation of a new object (very first time), this
situation indicates a problem with the number range status in the
control system. To solve the problem, contact SAP for support.

  Object Already Exists: The primary cause of this error is that the object you are trying to create already exists in the database. This can happen if:
  
  The migration process was run previously and the object was created.
  There was an incomplete or failed migration that left behind some objects.
  The object was manually created or modified outside of the migration process.
  
  
  
  Naming Conflicts: There may be naming conflicts if the same object name is used in different contexts or if there are multiple migration runs that attempt to create the same object.
