Hello Upadhyaya,
Thank you for your answer.
I did as you said. I have two conconated value, first one is F1 - F2 and F3 and second one is F1 F2 F3 and F4 but the thing is i have two input that based on this complex table. Regarding the data of above example, the first input should only show(F1 + F2 + F3); 01,02,03,04 and the second input should show(F1 + F2 + F3 + F4) GMD, KMD, ...., OTR.
The index of second input is the conconacated field of F1+F2+F3+F4 and it works ok.
The index of first input is the conconacated field of F1+F2+F3 but still shows dublicated value.
Those two index has no parent index.
I hope, i tell myself clear.
Regards,
Adem
