customising error for absent types in MSS team Calendar

Hi,

In our system we have 2 types of absent types:

1. Those that employees can request approval

2. Those that employees cannot request approval but can be applied through CATS by managers.

Now when a manager clicks on the leave type 2 (leaves which employees can request) in the team calendar, we get a critical error saying:

"There are no Customizing settings for absence type".

Can anyone please tell me what customising are msising? We ahve checked in Team calendar absent type settings and everything seems to be ok.

Thanks and reagrds,

Pinki
