FM READ_TEXT is not showing the data but the SAP standard transaction ME33L does show all the data

hello,

I am using FM READ_TEXT to read some texts (  EKPO, L03 ) but the FM is not showing any data. When I check the database table STXH also the DB table is not showing any data, but however, when I go to the SAP standard transaction ME33L ,  SAP  uses the same FM READ_TEXT  and the FM does show all the data !

If I debug the FM READ_TEXT  this is exactly the problem

1)  In my program when I use the FM  READ_TEXT

     syst-subrc = 4   (  not found )

2) In SAP program ,  when SAP uses the FM READ_TEXT

     syst-subrc = 0   (  everything ok !  )

 

any suggestions guys ?

thanks in advance,

Jimmy
