confirm that for each operating unit that you are selecting, the actual value is actually in the log file.
Below is a possible way that you can use to achive that:
1. Create a default package 'XX_PACKAGE_NAME_XML_PKG
2. Declare a variable of type Number (e.g LP_ORG_ID NUMBER;) in the package
3. Create a function AfterPForm that return a boolean
4. Assign the value of the org_id as follows:
5. Associate the dataTemplate with the default package XX_PACKAGE_NAME_XML_PKG
6. Create a tag as follows before the dataStructure tag:
<dataTrigger name="afterParameterForm" source="XX_PACKAGE_NAME_XML_PKG.AfterPForm" />
7. Define an element tag inside the dataStructure tag
dataType must be number and source="XX_PACKAGE_NAME_XML_PKG.LP_ORG_ID"
This should help in getting the value.
