Question

BizTalk newbie here...

I have a flat file output schema which consists of 4 child records, and for each input record, the map needs to write each of the child records. The issue that I am having is that the output is coming out in this order:

Rec 1 Rec 1 Rec 2 Rec 2 Rec 3 Rec 3 Rec 4 Rec 4

The specs call for the file in this order:

Rec 1 Rec 2 Rec 3 Rec 4 Rec 1 Rec 2 etc

I have tried creating the schema in several different ways, I have asked coworkers with more BizTalk experience, and I have googled 'til my eyes are crossed, but I have yet to find a solution.

I have considered, but not yet tried, using XSLT to sort the output, but the difficulty that I foresee in that method is that each of the child records is a different length and some of the child records have additional key fields.

Hoping someone has prior experience with this situation.

Here's the current output schema:

Solution

Your situation is fairly common and the solution an be pretty eash depending on home much control you have over the two schemas.

For your flat file, Rec 1-4 must be children of the same Parent:

<RecordsParent>
  <Rec1/>
  <Rec1/>
  <Rec1/>
  <Rec1/>
</RecordsParent>

RecordsParent should be maxOccurs=unbounded.

Then, from the source schema, use a Looping Functoid to connect the parent of Rec 1-4 sources to RecordsElement.

This will cause the Mapper to add an additional for-each around the parent elements which in most cases will give you the output you want.
