ID REFRESH • REFRESH ABAP Statement
REFRESH Short Reference
ABAP_SYNTAX_OBS REFRESH itab.
What does it do? This statement deletes all lines in an internal table itab. This releases the memory space required for the table, except for the initial memory requirement. The operand itab must be an internal table. The statement FREE can be used to delete all lines and release all memory occupied by these lines including the initial memory requirement. System Fields This statement always sets sy-subrc to 0.
Latest notes:
The statement REFRESH itab has the same effect on internal tables as CLEAR itab[]. If the internal table itab has a header line , the table body is initialized and not the header line.
If the internal table itab does not have a header line, REFRESH itab has the same effect as CLEAR itab. The use of tables with header lines is obsolete and forbidden in classes, which makes the use of REFRESH instead of CLEAR obsolete too. CLEAR or FREE can always be used to delete lines in internal tables. ABAP_HINT_END
Example ABAP Coding
