Leave deduction can be displayed using "leave dedution" option

What causes this issue?

From this menu item, you can display deduction for time quota records
(Infotypes 2006 and 2007). This is only possible if the absence record
to be deducted is <LS>not</> deducted from the quota type <LS>99</>
(Leave - old). The absence record currently being processed, however,
is deducted from this quota type.

System Response

The system can not carry out your request because the deduction of
leave from the Leave Entitlement infotype (0005) is not compatible with
deduction of other quota types.

How to fix this error?

If you want to see the quota deduction for the current absence, choose
instead <LS>Edit -> Leave deduction</>.
