Need Help to delet sort key! Please help!

Question

Hi,
I have a problem in the following program.
Source Code:
t-belnr  = bsid-zuonr.
SPLIT t-belnr at '#' into wk_belnr wk_x_belnr.
CLEAR t-belnr.
    t-belnr  = wk_belnr.
    t-xblnr  = bsid-belnr.
    IF t-belnr NE space.
      s-belnr      = t-belnr.
    ELSE.
      t-belnr      = t-xblnr.
      s-belnr      = t-xblnr.
    ENDIF.
IF t-xblnr NE space.                                    "WD041005a
      s-xblnr      = t-xblnr.                               "WD041005a
    ELSE.                                                   "WD041005a
      s-xblnr      = t-belnr.                               "WD041005a
    ENDIF.                                                  "WD041005a
    WHILE s-xblnr(1) EQ '0'.                            "INS MG130606
      SHIFT s-xblnr LEFT.                               "INS MG130606
    ENDWHILE.                                "INS MG130606
In the final ALV.
If first colum (t-zuonr) (sort key for the document )is blank, the document need to be deleted.
Question:
How can I write the code to deleted the t-zuonr when it is space?
Please help!!!
Thank you!!

Try as below:
DELETE <itab> WHERE <fld> IS INITIAL.
i.e
DELETE t WHERE zuonr IS INITIAL.
