I have in my prodn org test coverage of over 82%. I ran the Test-> runall test from developer console.
I want to move in a few fields and 2 classes and 1 test class into prodn. These 2 classes have coverage of 88% and 100%.
But when i moved the code thru change sets and deploy them. They give an error that my code coverage is 72%.
Is there any reason why the coverage is low when i deploy the changeset?
