IT2001: Specified Subtype is Invalid

Dear Friends,

Checked below thread with similar issue but no solution 😔 . So rephrasing my issue in details:

http://scn.sap.com/thread/596305

I've created various Absence quotas in IT2006 for an employee. But when I try to apply leave in IT2001, it pops up the message: Specified Subtype is Invalid. Those subtypes have been maintained in V_T554S When I bypass the message and proceed for creating absences it gives another error message : "Attendance/Absence type not valid for selected period" . I've checked date range for IT2006(01.01.2015 to 31.12.2015) and applied leave in Jan 2015 through IT2001.

We are using -ve Time Management only.
