I wanted to use TDS to create a message with the following structure:
Row 1 Length 5 n occurances
Row 2 Length 10 m occurances
Row 3 Length 6 x occurances.
n,m,x > 1 and unbounded.
All lines end with <CR><LF>
I know that I can't use Tagged delimited because the length is the only parameter to distinguish Row 1,2 or 3.
Using fixed length wants a value on MaxOccurances other than -1
I can only think of variable length delimited and all elements delimited.
But their usage is not working either.
I know I am setting some properties incorrectly or looks like this cannot be done without using a data pattern.
I am sure this was doable on 2.1
My current environment is V5.
Please advise

There's an option somewhere for "repeat til end of bitstream". That's what you want, I think.
Unless you mean that n is unbounded AND m is unbounded AND x is unbounded? That's probably going to be tricky.
Or is is that there will only be three <cr><lf>'s in there?

Jeff,
All m,n,x are unbounded.
Wasn't end of bitstream somewhere in CWF? and not TDS?

I think you'll have to use data patterns for this. But again, you may have issues if you have [row1<cr><lf>][row1<cr><lf>]...[row2<cr><lf>]...
Because there's not going to be anything that can tell the parser that row 1 has stopped repeating and row 2 has started.

Shouldn't the length of each line help me in distinguishing that?
But I think the parser needs to know before hand what kind of data it is handling and doesn't get around to determining an element type from its length.

I haven't used data patterns in MB before.
Is there a tutorial or something available?
I need to be able to map the length though as each row can be uniquely identified that way only.

You can set Data Element Separation to 'Use Data Pattern' and use a data pattern something like '.*(100)\r\n' where the 100 is the length of the line.
This assumes, of course, that each row type has a fixed length.
By the way - this is very strange message format. Why doesn't the source application identify the lines with a tag? What application is your flow replacing, and how does that application parse these records? |
