ID SUM • SUM ABAP Statement
SUM Short Reference
ABAP_SYNTAX SUM.
What does it do? The statement SUM can only be specified within a loop LOOP and is only respected within a AT-ENDAT control structure. Prerequisites for using the statement SUM are that the addition INTO is used in the LOOP statement, and that the specified work area wa is compatible with the line type of the internal table. Furthermore, SUM cannot be used when the line type of the internal table itab contains components that are tables themselves.
In a group level AT NEW compi and AT END OF compi, SUM calculates the sums of the numeric components to the right of the current group key for all lines of the current group level and assigns these to the corresponding components of the work area wa. In an elementary line type, there are no components to the right of the current group key and the work area wa remains unchanged.
In the group levels FIRST, LAST, and outside an AT- ENDAT control structure, for a structured line type the sum of all numeric components of all lines of the internal table is calculated and assigned to the corresponding components of the work area wa. For an elementary numeric line type, SUM sums the line values and assigns the sum to wa. For non-numeric elementary line types, SUM has no effect and the work area wa keeps its current value.
Latest notes: When the AT control structure is exited, the content of the current table line is reassigned to the work area wa. ABAP_HINT_END

Runtime Exceptions
Catchable Exceptions CX_SY_ARITHMETIC_OVERFLOW
Reason for error:
Overflow when calculating totals
Runtime error:
ADDF_INT_OVERFLOW
Reason for error:
Value too large when calculating totals in internal table, field too small
Runtime error:
SUM_OVERFLOW
Non-catchable Exceptions
Reason for error:
The statement SUM was used outside a LOOP processing of an internal table.
Runtime error:
SUM_NO_INTERNAL_TABLE
Reason for error:
The statement SUM was used within a LOOP processing belonging to another ABAP program.
Runtime error:
SUM_ON_FOREIGN_INTERNAL_TABLE
Reason for error:
The statement SUM was used within a loop starting with LOOP ... ASSIGNING.
