Unable to use flexfield lexical oracle.apps.fnd.flex.kff.segments_metadata

Question

EBS 11.5.10.2
XMLP 5.6.3
ARXAGMW.rdf
Hello,
I am trying to convert an Oracle Report to XML Publisher, and I am having problems getting lexicals in the Data Template to work.
I raised an SR for this since both related threads in this forum from two years ago were unresolved. Oracle had no answers for me, and told me to ask the question here.
So anyone who has any ideas, please chime in!
Here is a simplified version of the data template, narrowed down to just the use of the lexicals:
<?xml version="1.0" encoding="utf-8"?>
<dataTemplate name="XXWLC_ARXAGMW"
              description="samples from doco"
              defaultPackage=""
              dataSourceRef="ORA_EBS"
              version="1.0">
  <properties>
    <property name="xml_tag_case"       value="upper" />
    <property name="include_parameters" value="true"  />
    <property name="debug_mode"         value="on"    />
  </properties>
  <parameters>
    <parameter name="P_ID_FLEX_NUM" dataType = "number" defaultValue="101" />
  </parameters>
  <lexicals>
    <lexical type="oracle.apps.fnd.flex.kff.segments_metadata"
             name="FLEX_GL_BALANCING_APROMPT"
             comment="Comment"
             application_short_name="SQLGL"
             id_flex_code="GL#"
             id_flex_num=":P_ID_FLEX_NUM"
             segments="GL_BALANCING"
             show_parent_segments="Y"
             metadata_type="ABOVE_PROMPT"/>
    <lexical type="oracle.apps.fnd.flex.kff.segments_metadata"
             name="FLEX_GL_ACCOUNT_LPROMPT"
             comment="Comment"
             application_short_name="SQLGL"
             id_flex_code="GL#"
             id_flex_num=":P_ID_FLEX_NUM"
             segments="GL_ACCOUNT"
             show_parent_segments="Y"
             metadata_type="LEFT_PROMPT"/>
    <lexical type="oracle.apps.fnd.flex.kff.segments_metadata"
             name="ACCT_BAL_LPROMPT"
             application_short_name="SQLGL"
             id_flex_code="GL#"
             id_flex_num=":P_ID_FLEX_NUM"
             segments="GL_BALANCING"
             show_parent_segments="Y"
             metadata_type="LEFT_PROMPT" />
  </lexicals>
  <dataQuery>
    <sqlStatement name="Q_DOCO_SAMPLE">
      <![CDATA[
        SELECT
           &FLEX_GL_BALANCING_APROMPT alias_gl_balancing_aprompt
          ,&FLEX_GL_ACCOUNT_LPROMPT   alias_gl_account_lprompt
          ,&ACCT_BAL_LPROMPT          alias_acct_bal_lprompt
        FROM dual
      ]]>
    </sqlStatement>
  </dataQuery>
  <dataStructure>
    <group name="G_DOCO_SAMPLE" dataType="varchar2" source="Q_DOCO_SAMPLE">
      <element name="sample_gl_balancing_aprompt" dataType="varchar2" value="alias_gl_balancing_aprompt" />
      <element name="sample_gl_account_lprompt"   dataType="varchar2" value="alias_gl_account_lprompt"   />
      <element name="sample_acct_bal_lprompt"     dataType="varchar2" value="alias_acct_bal_lprompt"     />
    </group>
  </dataStructure>
</dataTemplate>The lexicals "compile" and run successfully, but they return String values that SHOULD be wrapped with quotes; but this doesn't happen, so the SQL that runs is:
SELECT
   COMPANY alias_gl_balancing_aprompt
  ,ACCT  alias_gl_account_lprompt
  ,CO          alias_acct_bal_lprompt
FROM dualThus, the concurrent program ends with ERROR, due to java.sql.SQLException: ORA-00904: "CO": invalid identifier
The first two lexicals and their corresponding sql statement are samples directly from the user guide (which is full of errors). The third lexical is the one from ARXAGMW.rdf.xml that I am trying to make work.

Answer 1

By the way, simply adding the quotes around the lexical names in the sql statement doesn't work. That causes the lexical references to be ignored as simple string values:
SELECT
   '&FLEX_GL_BALANCING_APROMPT' alias_gl_balancing_aprompt
  ,'&FLEX_GL_ACCOUNT_LPROMPT'   alias_gl_account_lprompt
  ,'&ACCT_BAL_LPROMPT'          alias_acct_bal_lprompt
FROM dualI turned on statement-level debugging via xdodebug.cfg and saw how it compiled the lexicals. By replicating the call to apps.fnd_flex_xml_publisher_apis.kff_segments_metadata that I found there, I was able to hack together a workaround for this issue.
Please point me to a better way of doing this if possible, as I had to GRANT EXECUTE on this apps package to my custom code schema. Is there a better lexical/flexfields reference than the XML Publisher documentation?
Here is the call I made in my before-report trigger:
--set ACCT_BAL_LPROMPT flexfield segment metadata lexical
begin
apps.fnd_flex_xml_publisher_apis.kff_segments_metadata(
  'FLEX_ACCT_BAL_LPROMPT',
  'SQLGL',
  'GL#',
  101,
  'GL_BALANCING',
  'Y',
  'LEFT_PROMPT',
  c_FLEX_ACCT_BAL_LPROMPT
end;
