Batch Voucher Process Error Messages

[sean]

Hi,
Can some body help me in resolving following error message of batch Voucher processing (R04110ZA).
1.I am not inserting any value into the Open amount (AAP) of F0911Z1.

Error : Open Amount is greater than Gross Amount.
Res : adjust open amount as less than or equal to gross amount.


2. Error : You do not have authority to fetch records from F0011.

And How to look into error exactly?

Thanks
Sean
