To use Character string operator in ABAP

Question

HI,
I have a problem with joining the two fields with different data length i.e
OBJKY has length (30).
tknum has length (10).
the above read table i_nast works as long as both has the records not greater than 10 and I do have some records with greater than 10 for OBJKY in the database and my read is failing at that scenario, I need to use a charater string operator, as I am new to ABAP, can any one suggest me how to do .
...SQL..
select OBJKY DATVR from nast
into corresponding fields of table i_nast
where KSCHL = 'ZBOL'.
sort i_nast by OBJKY.
LOOP at i_ship_data.
read table i_nast with key
OBJKY = i_ship_data-tknum binary search.
if sy-subrc = 0.
move: i_nast-datvr to i_ship_data-datvr.
endif.
modift i_ship_data.
ENDLOOP.

HI,
Since OBJKY and TKNUM are with different lengths the Read statement works only
when OBJKY has a 10 character value identical to TKNUM.
but if we can assume that only first 10 characters of OBJKY are to be comapred with TKNUM then we can try the under mentioned approach:
Create a new field in the Internal table I_NAST with length 10 characters.(I_NAST-OBJKY_TEMP).
now assign the first 10 characters of OBJKY to this new field :
LOOP AT I_NAST.
MOVE I_INAST-OBJKY+0(10) TO OBJKY_TEMP.
MODIFY I_NAST.
ENDLOOP.
Now you can Modify your READ STATEMENT :
LOOP at i_ship_data.
read table i_nast with key
OBJKY_TEMP = i_ship_data-tknum binary search.
if sy-subrc = 0.
move: i_nast-datvr to i_ship_data-datvr.
endif.
modift i_ship_data.
ENDLOOP.
Hope this will help.
Note: You can pick up any 10 characters starting from 1 to 20 th character of the field
I_INAST-OBJKY.
