IT0041 Date specification: not allowing two same date type

Hi,

I need to update the Infotype  0041: "Date specification"  attributes (customizing) to allow Two or more same date type :

Detail:

General attribute-

IT0041- date specification

Time constraint : 2

Sub type Obligatory : No

accounting /logdata: NO

Time const table: NO

Text allow : yes

maintain alt. leave : NO

sub type text table: no

access autho.: Yes

propose info type : No

apart above, IT0041 having 25 date Type following no. of  PA action. In the employee life cycle, it is possible to have two same action (Transfer, absconding) for one employee, but whenever user repeat a action twice (any action) system give error "Date type already existing"  i have tried by changing the Time constraint but error not solved due to IT0041 infotype is not having Sub type, Please suggest how to allow Two date type in IT0041?

Thanks,

Akhilesh
