OB52 AND OB08 transactions not working in QAS

Hi All,

My client is upgrading from 4.7 to ECC 6.0

Due to not modifiable status two transaction could't be done in the new QUALITY System.

This is IMG activity under the following.

1. OB52 :- Open and Close Posting periods (FA -> FA Global Setting -> Document ->Posting -> Open and Close Postinfg periods

2. OB08 :- Enter Foriegn exchange rate. (Gen Settings) Enter foriegn exchange rate

These transaction are to be executed regularly and directly in the 4.7 but in the present new ECC6.0 system the same is not possible due to non modifiable status. Now for testing in the new system we have to execute the same directly.

Please suggest
