Check box not selected in alv list
I have created a alv list with chek box in one column....
Having 2 buttons on the tool bar displaying APPROVE r REJECT.
After the selection of the Checkbox I need to go for APPROVE r REJECT.
but in my case ....
for eg consider there are abt 10 items in the list....
if i press 1st item means the process is ok.....but if i select for 5th & 6th in case the value is not selected...
LOOP AT T_YZA1 INTO W_YZA1.
IF W_YZA1-CHECK = 'X'.
W_YZA1-APPROVE = W_YZA1-CHECK.
MODIFY T_YZA1 FROM W_YZA1.
IF W_YZA1-CHEXK = 'X'.
CALL SCREEN 4.
