How To Fix NRSCNV142 - Temporary DSO &1 already exists (delete)

SAP Error Message - Details

• Message type: E = Error

• Message class: NRSCNV - Message class

• Message number: 142

• Message text: Temporary DSO &1 already exists (delete)

What causes this issue?

The check on DataStore object &V2& returned an error because an
DataStore object called &V1& already exists. Since the remodeling
framework will create a temporary DataStore object called &V1&, it must
be ensured that this DataStore Object does not exist before running the
remodeling rule. The reason for DataStore object &V1& existing could be
as follows:
DataStore object &V2& has already been remodeled before, but the
remodeling run did not finish successfully. The temporary DataStore
Object created during this previous run therefore was not removed
DataStore object &V1& is a real DataStore Object and was not created as
a temporary DataStore object during a previous remodeling run

System Response

Activating, scheduling or running the remodeling rule is not possible.

How to fix this error?

If the first of the two cases described above applies, simply delete
temporary DataStore object &V1& in transaction RSDODS. If the second
case applies, change the prefix character used to create a temporary
DataStore Object. In the default setting, the prefix character is <ZK>Z
</>. You can change this by opening the Configuration Screen by pressing
<ZK>Configure</>, or choosing <ZK>Remodeling Rule -> Configure</>.

Procedure for System Administrators

A temporary DataStore object created by the remodeling framework can
also be identified by its description, which should look something like
this: <ZK>TEMPORARY CUBE FOR REMODELING OF CUBE <(><<)></> DataStore
Object<ZK> name></>.

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

• What is the cause and solution for SAP error message NRSCNV142 - Temporary DSO &1 already exists (delete) ?

  The SAP error message NRSCNV142 indicates that a temporary DataStore Object (DSO) already exists in the system, and the system is unable to create a new one with the same name. This typically occurs during data loading or transformation processes in SAP BW (Business Warehouse) or SAP BW/4HANA.
  Cause:
  
  Existing Temporary DSO: The error arises when a temporary DSO with the same name is already present in the system. This can happen if a previous process did not complete successfully, leaving the temporary DSO in an active state.
  Concurrent Processes: If multiple processes are trying to create or use the same temporary DSO simultaneously, it can lead to conflicts.
  System Configuration: Misconfiguration in the data flow or process chain can also lead to this error.
  
  Solution:
  
  
  Delete the Existing Temporary DSO:
  
  Go to the SAP BW system and navigate to the Data Warehousing Workbench.
  Locate the temporary DSO that is causing the issue.
  Delete the temporary DSO manually if it is no longer needed. This can usually be done through transaction codes like RSA1 or using the Data Warehousing Workbench.
  
  
  
  Check Process Chains:
  
  Review the process chains that are running to ensure that they are not overlapping or trying to create the same temporary DSO at the same time.
  If necessary, adjust the scheduling of the process chains to avoid conflicts.
  
  
  
  Monitor and Clean Up:
  
  Regularly monitor the system for any orphaned or temporary objects that may not have been cleaned up after a process failure.
  Implement a cleanup job to remove temporary DSOs that are no longer in use.
  
  
  
  Error Handling:
  
  Implement error handling in your data loading processes to ensure that if a process fails, it can clean up any temporary objects it created.
  
  
  
  Consult Documentation:
  
  Refer to SAP documentation or notes related to your specific version of SAP BW for any additional troubleshooting steps or patches that may address this issue.
  
  
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as RSA1 (Data Warehousing Workbench), RSCONN01 (Connection Management), and RSPC (Process Chain Maintenance).
  SAP Notes: Check SAP Notes for any known issues or fixes related to this error message. You can search for NRSCNV142 in the SAP Support Portal.
  System Logs: Review system logs (transaction SLG1) for additional context or related error messages that may provide more insight into the issue.
  
  By following these steps, you should be able to resolve the NRSCNV142 error and prevent it from occurring in the future.
