The value of the Top property for the tablix ‘list1’ is negative. Negative sizes are not allowed.

This is a common issue in Dynamics NAV RDLC reports layout.

I have modified standard report a bit and when i try to save and compile the object it was keep prompting below error.

The strange thing was i haven't change the List control however it's complaining about that object.

Solution

Here it's mentioning the object name so go into the property of that object and check the location property and adjust the top valve or remove the minus sign(-)
