The EDIFACTWriter component is optimized for EDIFACT documents, providing a simple way to create EDIFACT documents.
The component allows you to create a document from scratch. The component allows you to create an EDI document one segment at a time. Here's how a document would normally be created:
- Call LoadSchema to load the necessary schemas for the transactions that will be used.
- Specify where to write the output document by setting the OutputFile property or SetOutputStream method, or set neither and check the OutputData property.
- Create a new interchange start segment using the StartInterchangeHeader method and set its properties using WriteElementString and WriteComponentString.
- To write a basic element value to the current location, call the WriteElementString method. For complex element values, there are two possibilities, elements which are split into components, and elements which repeat. To write these complex element values, use the StartElement and EndElement methods, with WriteComponentString and RepeatElement methods for writing the values. (Examples available below).
- Create a new functional group using StartFunctionalGroupHeader and set its properties using WriteElementString and WriteComponentString.
- Create a new transaction using StartTransactionHeader and set the properties for the header segment.
- Write all the data for the transaction by creating new data segments using StartSegment and providing the path of the segment to create using the schema names of the loops and segments, like /N1Loop1/N1.
- Once you are done with the segment, call EndSegment.
- Once you are done with the transaction, call CreateTransactionFooter.
- Once you are done with the functional group, call CreateFunctionalGroupFooter.
- Once the interchange is complete, call CreateInterchangeFooter.
Example EDIFACTWriter Code:
EDIWriter1.StartInterchangeHeader("D98B"); //Complex Element, two components EDIWriter1.StartElement(); EDIWriter1.WriteComponentString("UNOB"); EDIWriter1.WriteComponentString("1"); EDIWriter1.EndElement(); //Skip a value for this element EDIWriter1.SkipElement(); //Basic element EDIWriter1.WriteElementString("7654323"); ... EDIWriter1.StartFunctionalGroupHeader(); ... EDIWriter1.StartTransactionHeader("APERAK"); //Complex Element, repeated element EDIWriter1.StartElement(); EDIWriter1.WriteComponentString("UNH1"); EDIWriter1.RepeatElement(); EDIWriter1.WriteComponentString("UNH2"); EDIWriter1.EndElement(); ... //Segment and its data EDIWriter1.StartSegment("BGM"); EDIWriter1.StartElement(); EDIWriter1.WriteComponentString("C00"); EDIWriter1.EndElement(); EDIWriter1.StartElement(); EDIWriter1.WriteComponentString("C10601"); EDIWriter1.EndElement(); EDIWriter1.EndSegment(); ... CreateTransactionFooter(); CreateFunctionalGroupFooter(); CreateInterchangeFooter();
