Hi!

Mostly CLEAR clears only the table header. Use REFRESH to clear all records from and internal table.

If you are confused using CLEAR statement, then you can separate your internal table and the work area, like this:

DATA: gt_mara LIKE STANDARD TABLE OF mara,

wa_mara LIKE LINE OF gt_mara.

CLEAR wa_mara.

REFRESH gt_mara.

The message means you cannot empty the contents of an internal table whilst you are processing it i.e. you must do it outside the loop... so

loop at gt_data.
  clear: gt_data[].
endloop.

makes no sense as you are destroying the array you are looping around.

Just use "refresh gt_data." or "clear: gt_data, gt_data[]." outside a loop to drop the contents from memory.
