Joining 2 tables with periods

[chrisk44]

I've got problem with joining tables.
Source tables look like that:
TAB1
START
END
EMPL_KEY
EMPL_ID
STATUS
COMPANY_NO
1989-02-15
2007-02-08
123#1
1356

I've tried intervalmatch
 
EMPL_ID&'#'&"COMPANY_NO"&'#'&'STATUS' as AB_KLUCZ
AB_EMPL_ID&'#'&"AB_COMPANY_NO"&'#'&'1' as AB_KLUCZ
INTERVAL:
IntervalMatch("AB_START",AB_KLUCZ)
LOAD
START,
END,
AB_KLUCZ
Resident TAB1 where STATUS=1;

LEFT JOIN TAB2
 
But it gave me multiple periods in table 2.
 
I am Not sure if I express myself clearly but thank you in advance for your help
PS... EMPL_KEY is The Key in Tab1 nad AB_ID is The Key in TAB2.
