Technical system was updated in parallel session

[Former Member]

I'm trying to assign a system a product instance. When I click on the error correction link, 'Change Product Instance Assignments', I am presented with the error that the 'Technical system was updated in parallel session'. From what I've read, it's typically caused by opening the transaction twice.

So, here's what I did to reproduce the error.

1. Restarted the windows server.

2. Start the SAP system

3. Log in as an SAP Admin

4. Transaction: LVSM

5. Click on the Errors - Warnings tab

6. Click on the 'Change Product Instance Assignments'

What can I do to avoid this lockup?

Thanks again.
