Update work process has too high respose time.

Our functional team is facing issue while saving data in va03 transaction. IT prompts Sales order saved successfully and when we go to va02 and try to open getting error Document "SD document not in database or has been archived"

So when I checked sm66 update WP is on hold due to RFC response. and in st03 it has high response time

Task          steps  response time                                             wait time

UPDATE2    2       1.130,0               335,0    65,0    724,0    0,0    0,0                0,0    0,0    70,5

UPDATE    29        1.188.035,2       19,6    8,6    35,9    0,0         1.187.979,4    0,0    0,0    0,3

Also in SM13 all updates are at Initial status. Nothing get updated in database.
