ABAP RAW String not updating

If you have created a field of RAWSTRING type and while checking you will be seeing that when appending into the table and check in SE11 tcode, you may see that the field data is not visible.

Don't get panic, check once in SE16N and still its not visible then try by moving the field in the last in the SE11.

Add first line to field symbol
