ABAP 7.40: using function 'segment' instead of command 'split'

ralf_wenzel_heuristika — Sat, 23 Apr 2016 14:02:05 GMT

The following coding has to be translated into ABAP 7.40:

DATA:

source TYPE string VALUE 'MARA-MATNR=12345',

tabname TYPE tabname,

fieldname TYPE fieldname,

attribute TYPE string.

SPLIT:

source AT '-'

INTO tabname fieldname,

fieldname AT '='

into fieldname attribute.

" RESULT: tabname = 'MARA', fieldname = 'MATNR', attribute = '12345' !

I do not understand the F1 help of "segment" functions' features....

appendix:

via trial & error:

tabname = segment( val = source index = 1 sep = '-' ).
fieldname = segment( val = segment( val = source index = 2 sep = '-' ) index = 1 sep = '=' ).
attribute = segment( val = source index = 2 sep = '=' ).

any shorter codings?

Hi Ralf,

the documentation ABAP Keyword Documentation looka quite clear, But I don't see any advantage over SPLIT in this context.

Your code will run in 740 as it is. Translation is 1 : 1.

I have no idea what the special purpose of segment function may be - don't eve like the sample code for determining min an max as given here ABAP Keyword Documentation.

Regards Clemens

I am just training 7.40.... So my example may offer no advantages. But it IS an advantage to append a part of a field to an internal table without using help variables, for instance. In my example:

data:

tabnames type table of tabname.

append to_upper( segment val = source index = 1 sep = '-' ) ) to tabnames.

instead of

data:

tabnames type table of tab name,

helpfield_1 type tabname,

helpfield_2 type string.

split source at '-'

into helpfield_1 " only used as split target field

helpfield_2. " helpfield_2 never used, just a dummy!

translate helpfield_1 to upper case.

append helpfield_1 to tabnames.
