I knew that to write customer own logic, exits wuld b located in main prog. with the help of following statement,
<i>CALL CUSTOMER-FUNCTION '003'
xvbak = vbak
xvbuk = vbuk
xkomk = tkomk
lvf_subrc = lvf_subrc
xvbfa = xvbfa
xvbap = xvbap
xvbup = xvbup.</i>
So, my doubts r,
1- Under Export parameter, Which one is exporting, either its vbak or xvbak?
2- In Import paras, there is no X prefix either side! In Tables there is X prefix for either side! Why this difference? Is it just like that?
