To each document record, add the data fields which values must be exchanged. For external file-based documents, set up the fields in line with naming in the file.

For XML documents, fields are always of type string, to enable type conversions.

This topic explains how to add record fields to an XML document.

If fields are already initialized for the document, selected for the record, or copied to the record, you can review and complete the setup for these fields. To do so, skip step 6.


Standard procedure

1. Click Connectivity studio Integration Design.
2. Click the Documents tab.
3. In the list, find and select the desired XML document.
4. Click Edit.
5. In the Records section, in the Record list, find and select the desired record.
6. On the Fields tab, click New.
7. As a field name, enter a free-definable name. Usually, this is the name used in the external file.
  In the Field name field, type a value.
 

Note: The value of this field cannot have spaces.

8. As a record table, enter a free-definable name. Usually, this is the name used in the external file.
The value, as entered in the Field name field, is the default value. You can change this value.
  In the Record table field field, type a value.
 

Note: The value of this field cannot have spaces.

9. Indicate if the field is a key field for the record.
  Select the Key field check box.
10. Indicate if the field is mandatory to be filled. If on processing the document, the field has no value and Mandatory is set to:
- Yes, an error is given, and the document is not processed.
- Warning, a warning message is given, but the document is processed.
- No, the document is processed.
  In the Mandatory field, select an option.
11. Set the field length carefully. Make sure, the number of characters is sufficient to contain the value. If you set the length too short, you will use value characters.
  In the Length field, enter a number.
12. XML elements can have attributes. In a document, on a record, you can use a field value as attribute. Use the attribute type to define of which element the field is an attribute. You can choose these attribute types:
- Field: The field value is an attribute of another field element in the XML file. Make sure to fill in the Attribute of field.
- Root: The field value is an attribute of the root record element in the XML file.
- Expression: In a complex XML file, a value that is required for the current record, can be positioned at a different place. You can use an XPath expression to navigate through elements and attributes in an XML document to find the required value. Make sure to fill in the Expression field. Note: The XPath expression is only used on reading an XML file.
  In the Attribute Type field, select an option.
13. If you choose 'Field' as attribute type, define the field of which the current field is an attribute.
  In the Attribute of field, enter or select a value.
14. If the field name in the record differs from the attribute name in the XML file, define the attribute name in the XML file.
  In the Attribute name field, type a value.
15. If you choose 'Expression' as attribute type, define the XPath expression.
  In the Expression field, type a value.
16. On read, you can have the value not only searched for the in the record tag, but also in the children of the record tag. The first-found value is used.
  Select the Search in children check box.
17. On write, if the field has no value, the field is not written to the XML file. So, there's no reference to the field in the file at all.
  Select the Skip empty check box.
18. Sub-task: Set external references for record.
  18.1 In the Line details section, set the external references for the record.
You can indicate which of the records fields contains the unique ID of the record in the external database. In this way, you link the external ID to the record ID.
  In the External reference field, enter or select a value.
 

Note: Usually, you only use this for an ODBC connection with CRM or if you use web services.

  18.2 You can indicate which of the records fields contains the revision of the record in the external database. In this way, you find and link the latest revision to the record ID.
  In the Revision field field, enter or select a value.
 

Note: You can only use this field in combination with the External reference field.
