Authorization at profit center level

Dear All,

In FI Module we have a requirement of Authorization at Profit Center

Level.

For Example : in FB50 transaction we want to allow some users to enter

only for "1001" profit center.

We have tried the following :

We have create authorization object for PRCTR - Profit Center field and

assing that object manualy to role. But it is not working. After assigning this authoization object, profit center also comes in "Organization Level". But at transaction level no effect.

Thanks in adanace,

Nirav
