String Processing 2.3
LD_RESULT = |Monster Number { ld_number } / { ld_status }|.
Listing 2.18 Building Up a String Using Pipes
This gives you much better control of spaces and punctuation and the like; it’s
slightly more difficult to use text symbols but not impossible. Moreover, you can
pass such constructs (the text between the starting | and the ending |) into
parameters of method calls that are ex pecting strings. Previously, you had to
build up the string in a helper variable and then pass that into the method call.
2.3.2 New String Features in Release 7.4
If you’re anything like me, you may spen
d half your life calling the functions
CONVERSION_EXIT_ALPHA_INPUT and CONVERSION_EXIT_ALPHA_OUTPUT to add and
remove leading zeroes from document numbers like delivery numbers; for example,
you might remove the zeroes when showing messages to the user, but then
then add them back before you read the database (Listing 2.19).
“Remove leading zeroes before output to user
CALL FUNCTION ‘CONVERSION_EXIT_ALPHA_OUTPUT’
EXPORTING in = ld_delivery_number
IMPORTING out = ld_delivery_number.
ld_message = |Problem with delivery number { ld_delivery_number }|.
MESSAGE ld_message TYPE ‘I’.
“Now add the leading zeroes back before database read
CALL FUNCTION ‘CONVERSION_EXIT_ALPHA_INPUT’
EXPORTING in = ld_delivery_number
IMPORTING out = ld_delivery_number.
SELECT *
FROM LIKP
INTO CORRESPONDING FIELDS OF ls_delivery_header
WHERE vbeln = ld_delivery_number.
Listing 2.19 Removing and Adding Leading Zeroes by a Function Call
In ABAP 7.4, this can be done in a more compact manner by using the ALPHA formatting
option, which does the exact sa me thing as the two function modules
used in Listing 2.19. To remove the leading zeroes in 7.4, you can write code such
as that in Listing 2.20.
ld_message = |{ ld_delivery ALPHA = OUT }|.
MESSAGE ld_message TYPE ‘I’.
SELECT *
FROM LIKP
