Ambigous problem with a setfilter

Dear All,

I have created a perfectly-working report. Today I have decided to add a new set filter which is the item ledger filter. By commenting the code the report works perfectly but when removing the code it simply get stuck even though actually it is not being used.


SETRANGE("Date Filter",PeriodStartDate,PeriodStartDate[i+1] - 1);
SETFILTER("Item Ledger Filter",'Negative Adjmt.');
SETFILTER("Sales Type Filter", 'Stock');
CALCFIELDS("Sales (Qty.) - Sales TYpe", "Sales (LCY) - Sales Type", "Avg. Cost (LCY) - Sales Type");

Can anyone explaing to me this thing since I can't explain why this is happening. Please note that I have created the item ledger filter column and therefore am more than sure that it is not affecting anything.

Best Regards,

Stephen
