Cancellation of MIC Results arrived using formula
I have a critical problem. I am recording results for MIC in Inspection lot through QE51N. I recorded for operation 010, 020. For Operation 030, the results is arrived through formula where in it takes in to consideration of results of Op 020 and 030, when you press a calculator kind of icon in the item row. Now the problem is I have calculated results for 030 on pressing calculator icon and arrived at a results. Now i have found that results entered for 010 is wrong. So value for 030 is also obviously wrong. I want to cancel value for 030 but it is not happening. It is Grey and non editable.
How to do this ?
