Errors in standard programs after refresh

Hello Experts,

We recently upgraded our system to ERP EHP5.

Before that we have taken the refresh from Prod-QA system.

After the refresh there were transports which we didn't imported on QA since it was thought that the system should be tested as it is Prod.

But now the system are upgraded and we imported last 4 months transport including the SPDD/SPAU transports again,we are getting lot of dumps in standard programs like STMS,VA01 etc.

How should we correct this error situation and what will be best approach here.

Regards

Ajay Sandal
