KA,
Expert Rahul provided good advice. Sometimes the safety stock section of the standard macro "Safety Stk/Reorder Pt/Target Stock Lvl"
gets hosed (that's a technical term). Check the macro in standard vs. your copy. Go row by row. Sometimes the KF changes.
If you don't have the macro then either it wasn't copied from the standard when your book was created or it is not set as one of the default macros.
Come back if the macro is really OK.
Best regards,
Mike
