drop down lists using VRM_SET_VALUES

Hello All ,

i am calling VRM_SET_VALUES for drop down list, by exporting the ID and VALUES.

total i am passing 6 values, so first time when i am in selection screen , it is displaying 6 values. fine ia m happy with this.

after executing the selection screen , if i come back, and see the drop down list , now this contains 7 values, the extra 7th value is what i selected first time. (so what i selected first time is now coming again, this entry is duplicated, now this entry is displaying at the bottom of the list , in capital letters). i dont want this extra entry, can some tell a way how to remove this.

P.S. i searched SDN , i dint find any problem releated this

Thanks in advance.

Best Regards,

Amarender Reddy B.
