Easy ways to create and populate range tables in ABAP 7.4 onwards
2233102,570
Introduction
In certain cases, you need to create and populate range tables in ABAP for different purposes. So, in this blog post, I have explained 3 easy ways to populate range tables.
Solution
The ways are the following.
Using LET with VALUE. Please check the below section for quick reference.
TYPES lr_bukrs_type TYPE RANGE OF bukrs.
DATA : lr_bukrs_01 TYPE lr_bukrs_type, "Table 1
lr_bukrs_02 TYPE lr_bukrs_type. "Table 2
• Using only LET with VALUE
*--------------------------------------------------------------------*
lr_bukrs_01 = VALUE lr_bukrs_type(LET s = 'I'
o = 'EQ'
IN sign = s
option = o
( low = '0100' )
( low = '0200' )
( low = '0300' )
( low = '0400' )
( low = '0500' )
( low = '0600' )
( low = '0700' )
).
Using MACRO: This is the simplest way. Please check the below section for quick reference.
TYPES lr_bukrs_type TYPE RANGE OF bukrs.
DATA : lr_bukrs_01 TYPE lr_bukrs_type, "Table 1
lr_bukrs_02 TYPE lr_bukrs_type. "Table 2
• Using MACRO
*--------------------------------------------------------------------*
DEFINE range_bukrs.
lr_bukrs_01 = VALUE lr_bukrs_type(BASE lr_bukrs_01 (
sign = 'I'
option = 'EQ'
low = &1
)
).
END-OF-DEFINITION.*--------------------------------------------------------------------*
range_bukrs: '0100', '0200', '0300', '0400', '0500', '0600', '0700'.
*--------------------------------------------------------------------*
Using FOR LOOP: By this procedure, one can populate the range table w.r.t another table. Please check the below section for quick reference.
TYPES lr_bukrs_type TYPE RANGE OF bukrs.
DATA : lr_bukrs_01 TYPE lr_bukrs_type, "Table 1
lr_bukrs_02 TYPE lr_bukrs_type. "Table 2
• Using MACRO
DEFINE range_bukrs.
lr_bukrs_01 = VALUE lr_bukrs_type(BASE lr_bukrs_01 (
sign = 'I'
option = 'EQ'
low = &1
)
).
END-OF-DEFINITION.range_bukrs: '0100', '0200', '0300', '0400', '0500', '0600', '0700'.
• Combining LET with FOR LOOP
*--------------------------------------------------------------------*
lr_bukrs_02 = VALUE #( FOR ls_bukrs IN lr_bukrs_01• ( sign = 'I' "Alternatively
• option = 'EQ' "Alternatively
LET s = 'I'
o = 'EQ'
IN sign = s
option = o
( low = ls_bukrs-low )).
That’s it.

the first example can still be simplified,
DATA(burks_range) = VALUE lr_bukrs_type( sign = 'I' option = 'EQ'( low = '0100' )
( low = '0200' )
( low = '0300' )
( low = '0400' )
( low = '0500' )
( low = '0600' )
( low = '0700' ) ).
I personally find the other options not elegant and rather complicated.

Dear Andre,
Thanks for reviewing the blog post.
Yes, the example that you have provided is also right. The 'LET' keyword creates complicacy sometimes.
Regards,
Kallol

I actually like all three of the examples. It drives me crazy to create those range tables. My personal preference is the macro. However, someplace around here I read "Macros were bad". Not sure where...
My old way of doing it - is a simple loop within a class where the table and the field are dynamically passed. I know not very elegant - Hence I'm not sharing. I like these better.

You're right. There're two main reasons that I feel macros are not so good
You cannot debug through a macro. That's a biggest deal-breaker for me, as it's bad maintainability.
In this sort of example, it might still be considered if the 'filling' in range table is being done many times, but for one time it's an overkill. Moreover, even for many times, I wouldn't mind writing the 1 statement a few times as Andre shows in his comment above.

Here's where you can also read it: ABAP Programming Guidelines on Macros
It basically says "Only use macros in exceptional cases", but also that simple cases (like I would say this one is) are just fine...
Personally, as one of those "decisions that make other decisions easier", I prefer not to use them at all. For ranges specifically I use the UserName Placeholder for UXP-4318 UserName Placeholder for UXP-4318 version without the additional LET...

There's nothing you can do with a macro that you can't do equally well using methods or VALUE or ASSIGN.
If you feel there is somewhere where you need it, I'd bet you've got a bad program design!
TL;DR Don't use macros. They're BAAAAAAAAAAAAAAAAAAAAAAD.

My 2 cents...
data RANGE_OF_COMP_CODES type range of BUKRS.
select 'I', 'EQ', BUKRS from T001 up to 10 rows
into table @RANGE_OF_COMP_CODES.

Perhaps
SELECT 'I' AS sign, 'EQ' AS option, bukrs AS low, @space AS highFROM t001 UP TO 10 ROWS
INTO TABLE @DATA(range_of_comp_codes).

But i remember having some problem declaring the ranges in-line. Therefore, I do not use this construct.
High_Low_Diff_Datatype
I prefer declaring the range explicitly & then using it in the select.

Good point. Maybe
` ` AS high
would work.

Better yet, use cast
SELECT 'I' AS SIGN, 'EQ' AS OPTION, BUKRS AS LOW, CAST( @SPACE AS CHAR( 4 ) ) AS HIGHFROM T001 UP TO 10 ROWS
INTO TABLE @DATA(RANGE_OF_COMP_CODES).

Don't use macros - reason given above.
I use
DATA range_of_strings TYPE RANGE OF strings.
range_of_strings = VALUE #( ( sign = 'I' option = 'EQ' low = `cotton`)
( sign = 'I' option = 'EQ' low = `rope` )
( sign = 'I' option = 'EQ' low = `hemp` ) ).
I seem to recall you can also use
DATA range_of_strings TYPE RANGE OF strings.
range_of_strings = VALUE #( ( sign = 'I' option = 'EQ' low = `cotton`)
( low = `rope` )
( low = `hemp` ) ).

Well dang - I like these even better. My loop/end loop might be around a T table. So I'd have to see how it works - one line at a time.
I can see I need to think about ranges a bit longer.

Don't you mean this? (like Andre Kuller answer)
DATA range_of_strings TYPE RANGE OF strings.
range_of_strings = VALUE #( sign = 'I' option = 'EQ' ( low = `cotton`)
( low = `rope` )
( low = `hemp` ) ).

I love this blog. Just for all the comments it's been generating. It proves to me - again - it's worth writing a blog sometimes just to read the comments.

Sometimes you need to create a range table from another internal table. I use an SQL Expression for that. In the example below docitems is an internal table containing the BUKRS field.
SELECT DISTINCT'I' AS sign,
'EQ' AS option,
bukrs AS low,
CAST( ' ' AS CHAR ) AS high
FROM @docitems AS docitems
INTO TABLE @DATA(bukrs_range).

Instead of blank spaces, can specify exact number
SELECT 'I' AS SIGN, 'EQ' AS OPTION, BUKRS AS LOW, CAST( @SPACE AS CHAR( 4 ) ) AS HIGHFROM T001 UP TO 10 ROWS
INTO TABLE @DATA(RANGE_OF_COMP_CODES).

Can I ask you please on what release you are? This does not work on ABAP 7.50. Perhaps you are beyond this version?

We can also convert any column in internal table to a Rangle table in a single line of code like below.
DATA(RT_PERNR) = VALUE RSDSSELOPT_T( FOR WA_EMP1 IN IT_EMP ( SIGN = IF_FSBP_CONST_RANGE=>SIGN_INCLUDE OPTION = IF_FSBP_CONST_RANGE=>OPTION_EQUAL LOW = WA_EMP1-PERNR ) ).
