FM LDB_PROCESS doesn't work fine

Question

Hi everyone,
I need to access the logical database EHS_OH001 from a function, and I using the FM LDB_PROCESS to do this.
But when I've compared teh results using this LDB via a report (selection screen and GET event) and this function I noticed that the results don't match, I mean, the report resulted 1 record while the function didn't bring any record at all.
The code is below...thanks in advance!

type-pools: rsds, rsfs.
data: texpr type rsds_texpr,
      fsel  type rsfs_fields.
