Condition within loop not working correctly

Hi Experts,

I am passing a condition it should be false when loop flag set to Y but it's not working condition &Authorize_again& = N

loop condition is &Authorize_again& = Y. I am checking in WF log  Authorize_again = Y loop terminates after getting true in second time (Re_Authorization case) but this time if Authorize_again = Y why should not condition inside the loop is not set Y and getting failed. This is weird never faced like this because of this work item is getting duplicated.

Please help I have tried many combinations in last 24 hrs.

Thanks,

Saquib
