user want to change values for 4 columns but not at the same time.
For example customer has ABCD columns with values , EF are formula segregated columns....
If we change the values in the ABCD columns then EF columns will change that is fine.
All we need is
If user give value to column A then remaining columns BCD should be original data.
If user give value to column AB then remaining columns CD should be original data.
If user give value to column ABC then remaining columns D should be original data.
Or user want to give value to D then remaining ABC should be original data
The original data is available below.....
Please help
