Hi Amir,
Not used, but tried to find some technical info. let see whether its help you or not.
Actually once you select that check box its automatically insert one attribute as shown above.
Attribute name was 0RECORDMODE..
Its holds a value length of 1("X" or " "), its just like indicater. if you are familiar with ABAP. you can debug this below program.
X = indicate true
" " = indiacte false
Data element - RSDATRRECMODE
Prorgam name - SAPLRSD_GUI_IOBJ_MAINT
Field technical name - ATR_RECORDMODE(delete masterdata with 0recordmode)
Table - RSDGSCIOBJ
Table type - RSD_T_IOBJ_CMP -
Thanks
