SUM
Short Reference • SUM ABAP Statement
ABAP Syntax SUM.
What does it do? The statement SUM can only be specified within a loop starting with LOOP, and is only considered within a AT-ENDAT control structure. Prerequisites for using the statement SUM include using the addition INTO in the LOOP statement, and that the specified work area wa is compatible with the row type of the internal table. In addition, SUM cannot be used when the row type of the internal table itab contains components that are tables.
The statement SUM calculates the sums of the components withnumerical data type of all rows in the current group level and assigns the sums to the components of the work area wa. In the control levels FIRST, LAST, and outside of an AT-ENDAT control structure, the system calculates the sum of numeric components of all rows in the internal table.
