Cancel positive line send the whole requisition order through approval process

Hello everyone,

I have a problem cancelling requisition order lines and I need some help. This is the case step by step:

1. I create an OR with some lines (all positive amounts).
2. The OR goes through the approval process.
3. Once the OR is approved, we cancel one or more lines (positive amount).
4. The remaining lines goes through approval process again.

I have read this:

In 8.9 and later: Cancelled lines on the PO are forced to go back through approvals. None of the critical fields have changed. This is functioning as designed (Bug: 10958586) to prevent users from entering in credit lines to bring the amount under the approved amount. So when a line is canceled, the order still goes through the approval processing algorithm to determine if after the change the order is over or under the approval amount. If it is under, it will automatically approve all lines on the order. If it is over, all lines on the order will go through the approval route. This gives visibility to the approver to know that someone did something to the order. For example, a first level approval is set to $1,000.
