FixedElement

FixedElement inserts a constant value into an outbound document (in contrast with

ImpliedField, which inserts a constant value into the data store).

FixedElement has the following parameters:

• String tagName. This parameter is the XML tag of the data element to be

included in the outbound document.

• String value. This parameter is the value to be generated for the data element.

Here is the constructor for the FixedElement class:

public FixedElement(String tagName, String value)

Example:

The following example comes from the IDOC.HEADER. FixedElement is used to

populate header fields that are not captured in the data store but are required for SAP

XML schema validation.

FixedElement("TABNAM", "EDI_DC40"),

Concatenating Elements

The PrependFieldElement and AppendFieldElement classes map two elements into a

single table column by concatenation. PrependFieldElement specifies the first element;

AppendFieldElement specifies the second. You must specify either a unique separator

character or an element length, to permit the value to be separated into its constituent

parts when the IDoc needs to be reassembled for delivery to a client.

PrependFieldElement and AppendFieldElement have the following parameters:

• String tagName. This parameter is the XML tag of the data element.

• String columnName. This parameter identifies the database column in which the

data will be stored.

• Char separator. This parameter specifies the separator. You must specify either

this parameter or the length of the element.

• Int length. This parameter specifies the length of the element. You must specify

either this parameter or a separator.

PrependFieldElement and AppendFieldElement must be used as a pair.
