CALL TRANSFORMATION

[Former Member]

Hello.

I am making a small and simple example of a XML transformation.

The transformation i am using is the following:

<?sap.transform simple?>

<tt:transform xmlns:tt="http://www.sap.com/transformation-templates">

<tt:root name="ROOT"/>

<tt:template name="tmpl1">

<tt:loop ref=".ROOT" name="a">

<A>

<name>

<tt:value ref="$a.name"/>

</name>

<ZLS>

<tt:loop ref="$a.zls" name="z">

<Z>

<tt:value ref="$z.nummer"/>

</Z>

</tt:loop>

</ZLS>

</A>

</tt:loop>

</tt:template>

</tt:transform>

I can do the transformation from XML to ABAP tables without any problems but when i try to to it the other way (ABAP tables to XML) i get the following dump: CX_INVALID_TRANSFORMATION --> "Type of source and target must always be different for transformation START-OF-SELECTION"

The program i am using is the following:

data: xml_string type string.

data: begin of z,

number type string,

end of z.

data: begin of a,

name type string,

zls like table of z,

end of a.

xml_string = `<A>` &

`<name>A1</name>` &

`<ZLS>` &

`<Z>01</Z>` &

`<Z>02</Z>` &

`</ZLS>` &

`</A>` &

`<A>` &

`<name>A2</name>` &

`<ZLS>` &

`<Z>03</Z>` &

`</ZLS>` &

`</A>`.

CALL TRANSFORMATION ZMY_FRIST1

SOURCE XML xml_string

RESULT ROOT = t_a.

CALL TRANSFORMATION ZMY_FRIST1

SOURCE ROOT = t_a

RESULT XML = xml_string.

I get the dump on the second CALL TRANSFORMATION.

Anyone knows why and what can i do to fix this?

Thank you

why not use the standard XSLT program ID to convert to XML.

CALL TRANSFORMATION (`ID`)

SOURCE ROOT = t_a

RESULT XML = xml_string.

the simple tranformation you have written is for converting xml to abap not abap to xml

i hope you are aware that XLM transformation can be done in two ways

1. Simple transofrmation (the weblogs i have mentioned refers to that as you have used ST in your example)

2. XSLT

Hello.

Thank you for all the links.

Durairaj you said this is only for converting xml to abap, but why cant i use it for the opposite? What needs to be different?

I tryed using ('ID') like u said but the xml_string came out empty.

Thank you

try this sample code to see whether it works.

( ihave tested and it works)

REPORT Y_TEST_XML.

data: xml_string type string .

data: itab type standard table of sflight .

select * from sflight into table itab .

CALL TRANSFORMATION (`ID`)

SOURCE flights = itab[]

RESULT XML xml_string.

<i>Durairaj you said this is only for converting xml to abap, but why cant i use it for the opposite? What needs to be different?</i>

you need a different ST for that

Hello.

Thank you for all the help.

You say i need a diferent ST, but different in what way? What do i need to change in this one so it will work?

I tested an example from help.sap wich is identical (the difference is it uses a table of i instead of a defined table) and it worked.

Thank you

Hi Nuno,

1. itab --- > xml

xml ---> itab.

2. This program will do both.

(just copy paste in new program)

3.

REPORT abc.

DATA : t001 LIKE TABLE OF t001 WITH HEADER LINE.

DATA : BEGIN OF itab OCCURS 0,

a(100) TYPE c,

END OF itab.

f(255) TYPE c,

END OF upl.

my knowledge on ST is limited, can you check the weblogs i have mentioned.

Can anyone help me figuring why am i getting that exception?

Thank you

Hi Nuno, This is little irrelevant. All I want to know is the use of the command <ZLS> as used by you.

Thanks n regards, Prerna
