2599335 - Solution Locked by User SAP_SYSTEM. This Solution is Locked by Another Process


You are trying to carry out a Lifecycle Management task on your custom solution (e.g. Assemble , Downlaod etc..), however you cannot as you receive the below errors:

  • Unable to lock ONE_OFF YXXXXXXX_, it is locked by user SAP_SYSTEM.
  • This solution is locked by another process.
  • Try again later.


  •  SAP Cloud Application Studio SDK (All Versions).

Reproducing the Issue

  1. Open the SAP Cloud Application Studio SDK.
  2. Open the affected solution.
  3. Open the Implementation Manager.
  4. Attempt to carry out the Lifecycle Management activity on your solution.
  5. Errors will appear in the log files.


If this solution is uploaded to multiple tenants that are within the one physical system, you can use the functionality called Automated Distribution.

This means that if you have uploaded your solution to one tenant on this physical system, the Automated Distribution will then automatically update the version of the solution on all tenants within the one physical system.

The user SAP_SYSTEM is an SAP technical user that is used for background jobs in the system. This user is used for the task of Automated Distribution, hence if you try to download or make changes to your solution while the Automated Distribution is being carried out, you will see this error as this is expected that the user SAP_SYSTEM is still carrying out the Automated Distribution task.


The distribution of solutions can be unsuccessful due to two reasons as shown below, and can be solved by the below suggestions:

  1. Both the upload and activation of the solution had failed: In this case, you must trigger a restart of the upload of the solution by clicking on Automated Distribution . Both the upload and activation of the solution is automated.
  2. Only the activation of the solution has failed: In this case, you must login to the relevant tenant and manually activate the solution. For both the cases, you must check the version history logs for the respective tenants.
