Perfomance Issue

[Former Member]

Hi ,

Suppose I have got an internal table itab with field F1,F2,F3,F4.

Suppose itab F1,F2,F3 are already filled up with data . I want to fill field F4 based on Field F3 from a different table .

Take the example of F3 containing Vendor No . I want to get the Vendor name from LFA1 .

i dont want to use the below statement in bold

<b>select lifnr name1 from lfa1 into itab_lfa1 for all entries in itab where lifnr = itab-f3.

loop at itab.

read table itab_lfa1 with key lifnr = itab-f3.

-

---

endloop.</b>

Is there any way to select the data other than looping the itab itself .

sort itab_lfa1 by lifnr.

loop at itab.

at new lifnr.

read table itab index sy-tabix

select lifnr name1 from lfa1 into itab_lfa1 for all entries in itab where lifnr = itab-f3.

endat.

endloop.

Make sure LIFNR is the first field though.
