Quota Corrections Infotype (2013) 
You use this infotype to change accrual entitlements that are generated by time evaluation.
Time evaluation can generate and update records from the Absence Quotas infotype (2006) automatically. In the time evaluation run, the system first generates what are known as accrual entitlements. Your Customizing settings determine the time at which the accrual entitlements are transferred as a deductible quota to the Absence Quotas infotype (2006).
You can use the Quota Corrections infotype (2013) to influence how these accrual entitlements are generated and transferred from the table:
· You can increase, decrease, or replace an accrual entitlement (set to a fixed value).
· You can make the accrual entitlements available for deduction immediately in the Absence Quotas infotype (2006).

An employee has joined your company from another company. His or her contract has guaranteed a one-off entitlement of ten days of leave when the employee joins your company. You therefore want to increase the employee’s leave quota by 10 days. You want the entitlement to be immediately available in the Absence Quotas infotype (2006) so that the employee can take the ten days of leave.
You can only use the infotype to change absence quotas that are accrued in time evaluation. The changes are taken into account the next time that time evaluation is run. Time evaluation carries out a recalculation starting on the day for which you have entered the quota correction. You can view the results of the quota correction in the Quota Overview (transaction PT50).
Transfer time
The Absence Quotas infotype (2006) does not take account of quota corrections immediately. The infotype is updated at a specific transfer time that is determined in Customizing.
If you want to make the corrected accrual entitlements available directly in the Absence Quotas infotype (2006), you can also immediately transfer the accrual entitlements accumulated in time evaluation and the quota number specified in the infotype. You do this by setting the Transfer field to Transfer collected entitlement immediately.

An employee is leaving the company and wants to use the remainder of all his or her absence quotas that have not yet been transferred.
Replace and increase
In the case of automatic accrual, time evaluation can either replace or increase the existing accrual entitlements in the Absence Quotas infotype (2006). You will generally want to use the Quota Corrections infotype (2013) to change only accrual entitlements that are increased by time evaluation.

If the accrual entitlement is replaced by the quota correction, you can only choose the Transfer collected entitlement immediately function for quotas that are to be replaced. If the entitlement were not transferred immediately, time evaluation would overwrite the correction immediately.
If an accrual entitlement is replaced by the quota correction, you can only enter one record for each day. This is because a second quota correction would overwrite the first one, thereby making it void.
Customizing
