I have read and understand Cora Zimmermann's how to guide named "How to Protect Cells with non-Editable Key Figures". I have a requirement to prevent edits to a key figure (Sales Forecast) that are within the next four months AND permit edits to the same key figure (Sales forecast) for months five and beyond.
Can this be done within the S&OP toolset or will a Excel macro or L-code be required to satisfy the requirement?
