Credit hold updated by R42542 which is running in scheduler. It is observed that orders created on 2/22/2018 but went on credit hold on 3/2/2018 even though all of them are having eligible next status for the batch but didn't get hold till 3/2/2018.

Observed that most of them have any 1 lines cancelled on (3/2/2018) the order and order lines are future committed till 3/6/2018 but still got hold on 3/2/2018 by credit hold batch.

Can you please help me to understand if cancelling a line will trigger the credit hold batch to put the order on hold. I believe until unless order total is not increased hold wont be placed.
