Hi Michael,
If you choose to run the tool for the client specific tables in client 000, you will need to update the other clients. You can either run the sync tool in the other working clients or create a transport request to update it.
Let´s say that you have run the tool in your client 045, if you go to client 020 the entries will not be there, this is the reason that you need to create a transport or run the sync tool in client 020 as well.
In the old way of applying TUBs you should do the same, cascade the information to the other working clients. I could see a lot of customer didn´t do that, therefore just client 000 was update and the other working clients doesn´t have all SAP delivery entries in the other working clients. I could see a lot of customers receiving the error: "The system does not have the required TUB installed". This is the reason for the error, the SAR file was just applied in client 000.
I created a KBA talking about this.
2139409 The system does not have the required TUB installed
Hope I make this clear.
Kind regards,
Graziela
