Fm tseg_write_upd

Hi ,

I need advice about FM tseg_write_ upd. How I can enter testing data in SM37. import parameters are two tables ( header and event)

I cannot fin how edit fields and add some data. I can see table metadata bit not edit them.

Is it possibl eto replace FM spe/tseg_mod_timestam with tseg_write_upd and how?

Thanks

Chris
