  SELECT MARAMATNR MARAPRDHA
         MAKTMAKTX T179TVTEXT
         APPENDING CORRESPONDING FIELDS OF TABLE GT_WK_STORAGE

Hi,
I see one error in your code:
+FROM MARA AS MARA
INNER JOIN MAKT AS MAKT
ON MARAMATNR EQ MAKTMATNR
AND SPRAS EQ SY-LANGU+
how can you pretend to join tables MARA and MAKT with field SPRAS, when this field does not exist in MARA ??
I think you should modify your code this way:
SELECT MATNR PRDHA
into CORRESPONDING FIELDS OF GT_WK_STORAGE
from mara
WHERE MATNR IN S_MATNR.
SELECT single MAKTMAKTX T179TVTEXT
into CORRESPONDING FIELDS OF GT_WK_STORAGE
FROM makt inner join T179T
ON MAKTSPRAS EQ T179TSPRAS
WHERE MAKT~MATNR = GT_WK_STORAGE-MATNR
and   spras = sy-langu.
append GT_WK_STORAGE.
endselect.
Check the code, that I didn´t do it in SAP.
