Hi Experts,

I know there are lots of post related to this but nothing is working for my scenario.

Here is my scenario :

I have a Z table ZTAB1 which will be having feild names like F2 F4 F6 F7.

Lets say I do Select single * from Ztab2 into WA_ZTAB2.

THis WA_ZTAB2 is having feilds F1 F2 F3 F4 F5 F6 F7 F8 F9

Now in the out put i want to keep the data only in

wa-ZTAB2-F2

wa-ZTAB2-F4

wa-ZTAB2-F6

wa-ZTAB2-F7

Rest i want to clear them.

Please guide me how to achieve this

If possible please provide some code for this.

Thanks

Pravin
