Selection screen -Query

Question

Hi Gurus:
I have a query which has selections form extars tab in the
infoset and one selection for language from the selection tab.
The problem is that when this selection in teh selection screen
from the selection tab is filled with no language(blank)
and run withoutselecting anyother selection it gives all teh result,
similaryly if I put in a language and in it and run it still shows up
witha ll the result. Actually I would like to see only thiose
materials with description for which the language is entered and not all .
Since this selection copmes from teh selection tab fo the infoset
its not filtering as required but the other selection criteria which
comes from teh extra tab does filter accordingly.
Could anyone sufggest as how tyo gho about doing it so
that it shows the result by filtering from this languiage criteria also.
My selection screen is as follows.
(General data selection)
TDG Language                    ___<----- this comes from the selection tab in infoset
(Report-specific selection)
Material Number                 ____               to    ____ (these comes from the extra tab in infoset)
Material Type                   ____               to    ____
Material Desc. Language         ____               to    ____
Layout      ____
Thanks

Answer 1

I have two different columsn(additional field) for two diffrenet texts.
FOr the first one its :and its sequence is 2.
data: name3 type tdobname,
      language3 type spras,
      tlines3 type table of tline with header line.
language3 = sy-langu.
clear tdgtextz1.
name3 = mara-matnr.
call function 'READ_TEXT'
  exporting
    id                            = 'PRUE'
    language                      = language3
    name                          = name3
    object                        = 'MATERIAL'
  tables
    lines                         = tlines3
  exceptions
    others                        = 1.
if sy-subrc = 0.
  loop at tlines3.
    if sy-tabix = 1.
      tdgtextz1 = tlines3-tdline.
    else.
      concatenate tdgtextz1 tlines3-tdline into
          tdgtextz1 separated by space.
    endif.
  endloop.
endif.
if p_spras = language3.
check not tdgtextz1 = ' '.
tdg_text = ' '.
endif.
for the second one as follows and has the same sequence in infoset as 2.
data: name2 type TDOBNAME,
      language2 type SPRAS,
      tlines2 type table of TLINE WITH HEADER LINE.
language2 = sy-langu.
clear tdg_text.
name2 = mara-matnr.
CALL FUNCTION 'READ_TEXT'
  EXPORTING
    ID                            = 'PRUE'
    LANGUAGE                      = language2
    NAME                          = name2
    OBJECT                        = 'MATERIAL'
  TABLES
    LINES                         = tlines2
  exceptions
    others                        = 1.
IF SY-SUBRC = 0.
  loop at tlines2.
    if sy-tabix = 1.
      tdg_text = tlines2-tdline.
    else.
      concatenate tdg_text tlines2-tdline into
          tdg_text SEPARATED BY space.
    endif.
  endloop.
ENDIF.
if p_spras = language2.
check not tdg_text = ' ' .
tdgtextz1 = ' '.
endif.
