The DATACOPY calculation command copies data cells from one range of members to another range of members in a database. The two ranges must be the same size. For example, the following formula copies Actual values to Budget values:
DATACOPY Actual TO Budget;

FIX (Jan) DATACOPY Actual TO Budget; ENDFIX
