@ Veeram,
I've already checked Validity & deduction to & from dates in IT2006, it working fine from R/3 when i try to apply leave from IT2001.
@ Hari
we have screen number 2001 & deduction rule---->counting rule--->absence type assignment also also fine, bcz leave is deducting in IT2006 correctly when we applied from backend.
@ Raghavendra
I've already checked unapproved leaves which are in sent status (Red color) marked in calender.
but there are no leaves and i 've checked in PTARQ display document also, but not found any record from 18.04.2014 to 18.05.2014, but it available in PTREQ_ATTABSDATA table..
