How field Transaction type (Bseg-bewar) is populated ?

    Hello All,

I am trying to find out how the field BSEG-BEWAR is populated, I searched on internet but all i could find is technical data and propreties about this field ,

I am looking of the use of this functional use field, as in my actual SAP system, this field is not displayed , so may be it 's relateed to a spcific sub module or an add-on that we do not have...

any information can be really helpful.

regards

Thanks
