Currency precision in revenue management

Business case:

Currency: PKR

Currency precision (in Financial Reporting Structures) : 0

Extended Currency precision: 5

When we import customer contracts having revenue values up to 2 decimal places in oracle fusion revenue management from third party source system then it gives the following error during validate customer contracts source data process:

"you must enter a line amount that's the same as the quantity multiplied by the unit selling price in oracle fusion revenue management".

The values are exactly matched to decimal places and when we change the currency precision to 2 in financial reporting structures then there is no error during validate customer contracts source data.
