Collect statement not working

Dear Experts,

The collect statement is not working properly. There are 6 records in total and it is showing 2 in the output. It must show 1. All the character values are exactly same.

Following is my stucture:

      gs_final-tot_age1 = gs_bsid-wrbtr.
      gs_final-gsber = gs_bsid-gsber.
      gs_final-kunnr = gs_bsid-kunnr.
      gs_final-budat = gs_bsid-budat.
      gs_final-name1 = gv_name1.
      gs_final-ageing = '1 to 2 years'.

and following is the output:

ABC 1 - 2 years 5000 ABC LTD 10000.10

ABC 1 - 2 years 5000 ABC LTD     616.72

There should be one record Why not?

Regards

Mani
