In a sales order (with billing plan), only in 11th month billing, billing value differs

[ali-sd]

Dear all,

Please find the below issue.

How come 11th month billing has different billing value (refer below image)?
When 500 INR is entered manually (using condition type ZGSD), it should be same for all 11 months.
This happened only for few sales orders. But otherwise it works fine.

Condition tab details. Ctype ZGSD is entered manually during SO creation.

CType ZGSD item details - might help for further analysis

Awaiting for response please...

Your last period is from March 31st until April 27th (28 days), whereas the contract runs until April 29th (30 days). Hence 500/30*28 = 466.67
