wrong posting key coming during the accrual/deferral run for contract after reversal

Dear Expert,

I am facing one issue during the accrual/deferral run for the real estate contract...

when i run accrual/deferral process for a contract first time it generate the accounting entries with the posting key Inception(I), which is right. And if i run the reversal of accrual/deferral for the same entries it generate the accounting entries with the posting key Change of Inception(U), which is also right.

But after reversal if i run the accrual/deferral process for same contract it the generate the account entries with the posting key(U) only instead of inception (I), which is wrong.

Kindly guide me.

Thanks
