select single as the name implies gets a single record based on some condition while select up to 1 rows is the same except that for example, you can get the latest value by adding the statement ORDER BY in you select statement. Here is an example:

***SELECT SINGLE

SELECT single bukrs anln1 gjahr

afabe knafa kansw

answl kaafa nafal

aafav aafag nafap

aafap nafav nafag

FROM anlc INTO (it_anlc-bukrs, it_anlc-anln1, it_anlc-gjahr,

it_anlc-afabe, it_anlc-knafa, it_anlc-kansw,

it_anlc-answl, it_anlc-kaafa, it_anlc-nafal,

it_anlc-aafav, it_anlc-aafag, it_anlc-nafap,

it_anlc-aafap, it_anlc-nafav, it_anlc-nafag)

WHERE anln1 EQ it_anla-anln1

AND anln2 EQ it_anla-anln2

AND bukrs IN r_iwerk

AND afabe EQ '01'.

***SELECT UP TO 1 ROWS

SELECT bukrs anln1 gjahr

afabe knafa kansw

answl kaafa nafal

aafav aafag nafap

aafap nafav nafag

FROM anlc UP TO 1 ROWS

INTO (it_anlc-bukrs, it_anlc-anln1, it_anlc-gjahr,

it_anlc-afabe, it_anlc-knafa, it_anlc-kansw,

it_anlc-answl, it_anlc-kaafa, it_anlc-nafal,

it_anlc-aafav, it_anlc-aafag, it_anlc-nafap,

it_anlc-aafap, it_anlc-nafav, it_anlc-nafag)

WHERE anln1 EQ it_anla-anln1

AND anln2 EQ it_anla-anln2

AND bukrs IN r_iwerk

AND afabe EQ '01'

ORDER BY gjahr DESCENDING.

ENDSELECT.

In the example, select single will get the record that matches your condition unlike in select up to 1 rows it will get the latest record since I am ordering it by GJAHR(Fiscal year) in descending order.

Hope this helps...

P.S. Please award points for useful answers.

Select Single -> You need to specify all the key fields

Select upto 1 rows - > Keys fields are not required.

Select Single is not a loop.

Select Upto 1 rows is a Loop. So you have to specify SELECT & ENDSELECT.
