FREE

Short Reference

FREE dobj.

Effect

The statement FREE deletes all lines from an internal table and releases the memory area that was occupied by the lines.

On other data objects, FREE works like the statement CLEAR.

If dobj is a structure with tabular components, the memory of all the tabular components is released.

Notes

• If dobj is an internal table with a header line, FREE only affects the table body and not the header line.

• Unlike CLEAR, the initial memory area (see INITIAL SIZE) remains unoccupied when FREE is used. This can become necessary when there is a lack of memory.

• In general, FREE should only be used if the entire memory is to be released completely and the internal table is no longer needed or at the least not filled immediately.

• See also Memory Requirements of Deep Data Objects.
  
  

Example

At the breakpoints in the memory analysis of the ABAP debugger, it can be observed that FREE releases more allocated bound memory than CLEAR.
