Getting Error In the Routine - While writing Code for the Cross Reference.

Question

Hi,
Getting Error In the Start Routine - While writing Code for the Cross Reference from the Text table ( /BIC/TZMDES with Fields /BIC/ZMDES(Key),TXTSH ) Getting Error as [ E:Field "ZMDES" unknown ].
Transformation : IOBJ ZPRJ3(Source) -> IOBJ ZPRJC ( Target ).
The Source  Fields are: 0logsys(Key),zprj3(Key),ZDOM3.
The Target Fields are : 0logsys(Key),zprjc(Key),ZDOM3, UID.
Here i am trying to Update the target Field UID by Comparing the Source Field [ zprj3(Key)] with the Text table ( /BIC/TZMDES ) and update the UID.
The Code is as below:
Global Declarations in the Start Routine:
Types: begin of itabtype,
        ZMDES type /BIC/TZMDES-/BIC/ZMDES,
        TXT type /BIC/TZMDES-TXTSH,
         end of itabtype.
data : itab type standard table of itabtype
with key ZMDES,
wa_itab like line of itab.
Routine Code :
select * from /BIC/TZMDES into corresponding fields of table itab for
all entries in SOURCE_PACKAGE
where ZMDES = SOURCE_PACKAGE-/BIC/ZPRJ3.
READ TABLE itab INTO wa_itab
WITH KEY ZMDES = SOURCE_PACKAGE-/BIC/ZPRJ3
BINARY SEARCH.
IF SY-SUBRC = 0.
RESULT = wa_itab.
CLEAR wa_itab.
The tys_SC_1 structure is :
BEGIN OF tys_SC_1,
     InfoObject: 0LOGSYS.
        LOGSYS           TYPE RSDLOGSYS,
     InfoObject: ZPRJ3.
        /BIC/ZPRJ3           TYPE /BIC/OIZPRJ3,
     InfoObject: ZDOM3.
        /BIC/ZDOM3           TYPE /BIC/OIZDOM3,
     Field: RECORD.
        RECORD           TYPE RSARECORD,
      END   OF tys_SC_1.
    TYPES:
      tyt_SC_1        TYPE STANDARD TABLE OF tys_SC_1
                        WITH NON-UNIQUE DEFAULT KEY.
Please suggest with your valuable inputs.
Thanks in Advance

I have split the code in two.. one for start routine.. other for field routine.. hope this helps
Types: begin of itabtype,
ZMDES type /BIC/TZMDES-/BIC/ZMDES,
TXT type /BIC/TZMDES-TXTSH,
end of itabtype.
data : itab type standard table of itabtype
with key ZMDES,
wa_itab like line of itab.
Start routine
select * from /BIC/TZMDES into corresponding fields of table itab for
all entries in SOURCE_PACKAGE
where ZMDES = SOURCE_PACKAGE-/BIC/ZPRJ3.
Sort itab.
field routine
CLEAR wa_itab.
READ TABLE itab INTO wa_itab
WITH KEY ZMDES = SOURCE_FIELD-/BIC/ZPRJ3
BINARY SEARCH.
IF SY-SUBRC = 0.
RESULT = wa_itab-<field name>
