Rename screen problem

I am writing a dialog problem which will call screen 9100 by:

CALL SCREEN '9100' .

Today, I rename the screen number from 9100 to 9020 by:

CALL SCREEN '9020'.

All of PBO/PAI modules is udpated as well, but

I still got an error "DYNPRO NOT FOUND".

From the error message, I found the program still pointing to 9100.

I try to copy the screen 9100 to 9020 instead of rename but still the same error.

I also try download and upload the screen but still the same error.

The SAP version is ECC6.0.

Do I miss any step or is there any OSS note to fix this problem?

Thank you.
