BAPI to convert J_3GEMPRO

Hello guys if you go to J_3GBELP from SE16N tcode, you can see the fields J_3GEMPRO and J_3GEMPSP, but shows other information:

you need go in from SE16:

as you can see _3GEMPRO and J_3GEMPSP has numeric information, to show information like other screen you need run the BAPI  CONVERSION_EXIT_ABPSP_OUTPUT this is only for J_3GEMPSP

I think the J_3 GEMPRO is ever the seven first numbers of J_3GEMPSP but Im not sure.

Please help
