1. Goals

The goal with this tutorial is to understand how to create a payload based upon information inside the ENOVIA™ DB and transfer the data into some external location.

In this tutorial we will both illustrate how you can trigger a data-transfer both manually, but also based upon events inside ENOVIA™, for example modify-attribute event.

We will in this use case publish data onto a JMS queue.

1.1. Configuration File Structure

During this tutorial, we are going to create the following kind of configuration file structure.

You can download configuration files described in this tutorial.

Figure 1. Configuration File Structure

2. First, the Data Format

From ENOVIA™, we will publish data that follows this format:

<part-data>
    <name>...</name>
    <description>...</description>
    <status>...</status>
    <unit-of-measure>...</unit-of-measure>
    <last-modified>...</last-modified>
    <created>...</created>
    <bill-of-material>
        <row qty="..." findNumber="..." refDes="..." item="..." />
        ...
    </bill-of-material>
</part-data>

3. The Payload

The payload configuration is responsible for producing data according to your business rules.

TIF has a wide range of support that allows you to create the payload in different ways. In this tutorial we look into using a couple of different alternatives like

Using the Templating support (Apache Freemarker)
XSLT
Use of so called XML-Spec configurations to adjust the generated XML without further processing.

${TIF_ROOT}/modules/enovia/cfg/payload/SingleLevelEBOM.xml

<Payload rootElement="part-data">
    <TableContent outerElement=""> (1)
        <Table>SingleLevelEBOM_1.xml</Table>
        <XMLSpec> <!-- NOTE: Can be put in a separate file and reused -->
            <IncludeTableHeaders>false</IncludeTableHeaders>
            <IncludeTableGroups>false</IncludeTableGroups>
            <AddColumnId>false</AddColumnId>
            <AddCellIndex>false</AddCellIndex>
            <AddColumnRef>false</AddColumnRef>
            <AddCellValueSize>false</AddCellValueSize>
            <OmitCellValueElement>true</OmitCellValueElement>
            <OmitRowAttributes>true</OmitRowAttributes>
            <UseColumnName>true</UseColumnName>
            <TableDataElement/>
            <RowElement/>
        </XMLSpec>
    </TableContent>

    <TableContent> (2)
        <DataSet>SingleLevelEBOM.xml</DataSet>
        <Table>SingleLevelEBOM_2.xml</Table>
        <Template>SingleLevelEBOM.ftl</Template>
    </TableContent>

    <TableContent> (3)
        <DataSet>SingleLevelEBOM.xml</DataSet>
        <Table>SingleLevelEBOM_2.xml</Table>
        <Transformer>SingleLevelEBOM.xslt</Transformer>
    </TableContent>
</Payload>

1	Section 1: Extract info about the Part and use XML-Spec to tweak the generated XML to reduce need for additional processing
2	Section 2: Use Freemarker Template to generate output
3	Section 3: Generates same output as section 2, just illustrate how to use XSLT instead of Template

In the first section we only use the context object, hence we do not need any data-set for retreival of data. We only specify a table, containing the select statements we are interested of.

Related configuration(s) below:

Here is the table we use to extract the meta data from the context object:

${TIF_ROOT}/modules/enovia/cfg/table/SingleLevelEBOM_1.xml

<?xml version="1.0" encoding="UTF-8"?>
<Table>
    <Column>
        <Name>name</Name>
        <Expression>name</Expression>
    </Column>
    <Column>
        <Name>description</Name>
        <Expression>description</Expression>
    </Column>
    <Column>
        <Name>status</Name>
        <Expression>current</Expression>
    </Column>
    <Column>
        <Name>unit-of-measure</Name>
        <Expression>${attribute[attribute_UnitofMeasure]}</Expression>
    </Column>
    <Column>
        <Name>created</Name>
        <Expression>originated</Expression>
    </Column>
    <Column>
        <Name>last-modified</Name>
        <Expression>modified</Expression>
    </Column>
</Table>

Here is the data set we use to expand the first level. Note that we remove the root node from the result.

${TIF_ROOT}/modules/enovia/cfg/dataset/SingleLevelEBOM.xml

<DataSet>
    <RemoveRoots>
        <Expand>
            <Depth>1</Depth>
            <From>true</From>
            <RelationshipPattern>
                <Relationship>relationship_EBOM</Relationship>
            </RelationshipPattern>
        </Expand>
    </RemoveRoots>
</DataSet>

Below is the table used for the EBOM rows:

${TIF_ROOT}/modules/enovia/cfg/table/SingleLevelEBOM_2.xml

<?xml version="1.0" encoding="UTF-8"?>
<Table>
    <Column usesBusinessObject="false">
        <Name>find-number</Name>
        <Expression>${attribute[attribute_FindNumber]}</Expression>
    </Column>
    <Column usesBusinessObject="false">
        <Name>quantity</Name>
        <Expression>${attribute[attribute_Quantity]}</Expression>
    </Column>
    <Column usesBusinessObject="false">
        <Name>reference-designator</Name>
        <Expression>${attribute[attribute_ReferenceDesignator]}</Expression>
    </Column>
    <Column>
        <Name>name</Name>
        <Expression>name</Expression>
    </Column>
    <Column>
        <Name>status</Name>
        <Expression>current</Expression>
    </Column>
</Table>

Here is the template used in section 2:

${TIF_ROOT}/modules/enovia/cfg/template/SingleLevelEBOM.ftl

<#ftl output_format="XML">

<bill-of-material>
    <#list data.rows as row>
        <row
                   qty="${row.getCell("quantity").getFirstValue().getValue()}"
            findNumber="${row.getCell("find-number").getFirstValue().getValue()}"
                refDes="${row.getCell("reference-designator").getFirstValue().getValue()}"
                  item="${row.getCell("name").getFirstValue().getValue()}"
                status="${row.getCell("status").getFirstValue().getValue()}" />
    </#list>
</bill-of-material>

And finally, the XSLT stylesheet used in section 3:

${TIF_ROOT}/modules/enovia/cfg/xslt/SingleLevelEBOM.xslt

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0"
    xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">

    <xsl:output omit-xml-declaration="yes" indent="yes"/>
    <xsl:strip-space elements="*" />

    <xsl:template match="/">
        <xsl:element name="bill-of-material">
            <xsl:for-each select="//row">
                <xsl:apply-templates select="." mode="ebom" />
            </xsl:for-each>
        </xsl:element>
    </xsl:template>

    <xsl:template match="row" mode="ebom">
        <xsl:element name="row">
            <xsl:attribute name="findNumber"><xsl:value-of select="cell[1]/value[1]/text()"/></xsl:attribute>
            <xsl:attribute name="qty"><xsl:value-of select="cell[2]/value[1]/text()"/></xsl:attribute>
            <xsl:attribute name="refDes"><xsl:value-of select="cell[3]/value[1]/text()"/></xsl:attribute>
            <xsl:attribute name="item"><xsl:value-of select="cell[4]/value[1]/text()"/></xsl:attribute>
            <xsl:attribute name="status"><xsl:value-of select="cell[5]/value[1]/text()"/></xsl:attribute>
        </xsl:element>
    </xsl:template>
</xsl:stylesheet>

3.1. Testing the Payload

It is possible to test the payload via the Admin UI.

The following URL syntax can be used:

http://localhost:8181/enovia/admin/testPayload?objectId=53160.3064.60233.1057&payloadCfg=SingleLevelEBOM.xml&clearCache=true

Accepted parameters are:

objectId: The ENOVIA id of the object to create payload for
payloadCfg: The name of the payload configuration to test
clearCache: Force clear cache

4. Destination

${TIF_ROOT}/etc/destinations.xml

<Destinations>
    <JMS id="single-level-ebom"
         initialContextFactory="org.apache.activemq.jndi.ActiveMQInitialContextFactory"
         providerURL="tcp://172.16.16.210:61616">
        <Queue name="single-level-ebom" jndiKey="queue.%s"/>
    </JMS>
</Destinations>

5. Job Configuration

The Job configuration will put the pieces together, e.g in this example we use a transfer-data job and in such configuration we specify the payload to be used along with where to send the data.

${TIF_ROOT}/modules/enovia/cfg/jobcfg/SingleLevelEBOM.xml

<Job>
    <Name>Single Level EBOM</Name>
    <TransferData>
        <Payload>tvc:payload/SingleLevelEBOM.xml</Payload>
        <Destinations>
            <JMS id="single-level-ebom" messageType="text"/>
        </Destinations>
    </TransferData>
</Job>

6. Launch Job Manually

Below is a command defined in XML format that can be used by for example the TVC Structure Browser. If you need to use the command in a different context you need to create a corresponding Command object inside the ENOVIA™ database and assign it to the desired Menu.

<?xml version="1.0" encoding="UTF-8"?>
<!-- Sample command for creation of a TIF job manually -->
<Command>
    <Label>Send Part to ...</Label>
    <URL action="/tifCreateJob"
         submit="true"
         target="tableHiddenFrame">
        <Param name="job" value="SingleLevelEBOM.xml"/>
    </URL>
    <RowSelectType>single</RowSelectType>
</Command>

7. Launch Job via Trigger

You need to add the following trigger program object to enable this:

add bus "eService Trigger Program Parameters" "PolicyECPartStateApprovedPromoteAction" "TransferDataToERP"
    vault "eService Administration"
    policy "eService Trigger Program Policy"
    current Active
    "eService Program Name" "TIFTrigger"
    "eService Method Name" "newJob"
    "eService Program Argument 1" "${OBJECTID}"
    "eService Program Argument 2" "SingleLevelEBOM.xml";
