Hello, grues! 
Recently faced a problem with PT_QTA10 report.
If I run the report on the date of the beginning of vocation quota (in 2006 IT) it shows the hole quota per year in "Total Remain" column. Then I run the report for the same Personal Number on other date (later) and it shows the correct residue per date.
In my opinion the report must show me 0 balance on the first date of the quota period, but it show the hole quota.
Does anybody faced the same problem and how did you solve it?
Thank you in advance!
