While formulating a condition for ALV IDA, I see the below example.
* Add the required condition
data(lo_condition) = lo_alv_cond_fac->between( name = 'POSNR' low = '000010' high = '000030')->AND( lo_alv_cond_fac->equals( name = 'VBELN' value = '0000000010' ) ).
I need some help in understanding the usage of "->AND".
why does this usage not return any syntax error?
