On December 2021, the ECHA updated the “PCN: a practical guide” to its version 5.0. A version which includes a step-by-step explanation of the new functionality for disable submitted notifications through the ECHA submission portal, which was introduced in IUCLID 6 (version 6.20.)
Now, the ECHA submission portal allows companies to disable a successfully submitted dossier when they need it because:
This new function is only accessed in very specific circumstances, namely, when incorrect data has been submitted and cannot be corrected in any update.
In those cases, only the latest valid submission (e.g. if the notification has been updated) will offer this feature. Thus, in case of updated submissions, it is only possible to disable the latest submission, and then, the company may also consider to disable the initial submission as well.
The “Dissable Submission functionality” can be accessed via the three dots “...” from the submission report:

Then, once the request to disable the submission has been confirmed, it will generate a number assigned to it, in order to track the process down in the ECHA Submission portal:

Finally, it is important to notice that, once the submission has been successfully disabled, it is the responsibility of the company to inform downstream customers who may be affected by the disabling process as there is no communication to inform those companies who make reference to such submissions.
