Leave type to deduct two absence quota simultaneously

Hi All,

I am facing issue for deduction of quota.

Scenarioa is like that

Leave type ADV is assigned with quota 04 and

Leave type ADV1 is assigned with quota 44.

Whenever i will apply a leave ADV1 for two hours, my quota 44 should get deducted for 2 hours and simultaneously quota 04 also should get deducted by 2 hours.

I have created one deduction rule AA, where i have assigned two quota (44 & 04) there, but SAP is deducting the quota sequentially as once quota 44 exhausted then quota 04 will deduct.

but

my client want to deduct the two quota's simultaneously.

Please help me out.

Thanks in advance.

Sandeep.
