The order does not fall within the relevant approval rule

Hi,

I created the approval rule according to my project group.

I have two approval rules, T-SAS001 and T-SAS002.

While the priority of T-SAS001 is 20, the priority of the other approval rule is 21.

Currently, when I select the project code that falls within the scope of the approval rule with priority 21, it falls into the approval rule with priority 20. What should I do?
