ST - tt:include , Including Transformations
Syntax
tt:include name="trafo" [templates="tmpl1 tmpl2 ..."] /
Effect
The tt:include statement can be used to embed a different ST
program trafo in an ST program: This statement makes
the templates and type definitions of the included program usable in the
current ST program. The ST program trafo must exist
actively in the repository. trafo is not case-sensitive.
The ST command tt:include can be executed in an ST
program only outside of templates. In the default setting, it includes
all named templates of transformation trafo at transformation
level (unnamed main templates are not
included). Make sure that no namespace conflicts occur; a transformation
is not allowed to include itself.
If you specify the attribute templates , only the templates
tmpl1 tmpl2 specified there and the templates called by them using
tt:apply are included.
Note
Only those transformations can be included (in another transformation)
whose named templates are not in conflict with the existing named
templates. Using tt:apply , you can use
the included named templates as subtemplates in "including" templates.
Example
The ST program below corresponds to the example from
Subtemplates Without Their Own Data Roots
except that the subtemplate of an included ST program is used.
<(><<)>tt:transform template="TEMP_MAIN"
xmlns:tt="http://www.sap.com/transformation-templates">
tt:root name="ROOT"/
<(><<)>tt:template name="TEMP_MAIN">
<(><<)>week>
<(><<)>day1 tt:ref="ROOT.DAY1">
tt:apply name="TEMP_SUB" /
<(><<)>/day1>
<(><<)>day2 tt:ref="ROOT.DAY2">
tt:apply name="TEMP_SUB" /
<(><<)>/day2>
...
<(><<)>/week>
<(><<)>/tt:template>
tt:include name="..." /
/tt:transform
The statement tt:include could also be placed before the main
template. The included ST program can be implemented as follows:
<(><<)>tt:transform
xmlns:tt="http://www.sap.com/transformation-templates">
<(><<)>tt:template>
...
<(><<)>/tt:template>
<(><<)>tt:template name="TEMP_SUB">
<(><<)>name>
tt:value ref="$ref.name" /
<(><<)>/name>
<(><<)>work>
tt:value ref="$ref.work" /
<(><<)>/work>
<(><<)>/tt:template>
/tt:transform
