Hi All,
I am working on WMB6.1 and need to create below message definition in MRM domain TDS Format. First of all I would like to know whether we can create such a structure or not. If possible how I can go ahead.
| Code: |
HeaderStart (Tag to indicate Header line started)
Field1, Field2, Field3
HeaderEnd (Tag to indicate Header line ends here)
LineStart (Tag to indicate Line started) --> ( Occurence 0 to N)
Field1, Field2, Field3
SubLineStart (Tag to indicate Sub line started)--> ( Occurence 0 to N)
Field1, Field2, Field3
SubLineEnd (Tag to indicate Sub line ends here)
LineEnd (Tag to indicate Line ends here) |
I am able to structure the message with Header and Line items but not understanding how to go ahead with SubLine element creation
Thank You
Regards
Satya |

Note that Field1, 2 and 3 are all fixed length fields, created from CobolCopy text files.
Basically its clubbing of 3 CopyText files to create one complex structure and a mesage definition...... |

| Is there any CRLF in this message? Does ',' exist between Field? Please provide a sample to show the details. |

Yes we have CRLF between each lines as a record delimiter. Comma ',' does not exist between the fields. Sample example looks as below
| Code: |
HeaderStart
AAABBBCCC
HeaderEnd
LineStart
EEEFFFGGG
LineEnd
LineStart
EEEFFFGGG
SubLineStart
HHHIIIJJJ
SubLineEnd
LineEnd |
Fields values I have given with 3 similar Alphabets. In above example 2 line records are present. First Line record not having any SubLine records.
Thanks for the reply |

Yes - it's definitely possible to parse your message.
Your sample looks a little strange. Is it really like this:
| Code: |
HeaderStart
AAABBBCCC<CR><LF>
HeaderEnd<CR><LF>
LineStart<CR><LF>
EEEFFFGGG<CR><LF>
LineEnd<CR><LF>
LineStart<CR><LF>
EEEFFFGGG<CR><LF>
SubLineStart<CR><LF>
HHHIIIJJJ<CR><LF>
SubLineEnd<CR><LF>
LineEnd<CR><LF> |
or is it like this:
| Code: |
HeaderStartAAABBBCCCHeaderEnd<CR><LF>
LineStartEEEFFFGGGLineEnd<CR><LF>
LineStartEEEFFFGGGSubLineStartHHHIIIJJJSubLineEndLineEnd<CR><LF> |
The difference is quite important, as it will affect the setup of the model.
I assume that you want subLine to be a child of Line in the message tree. |

My Sample message is like shown below. SubLine is a child element for Line record, you are correct.
| Code: |
HeaderStart<CR><LF>
AAABBBCCC<CR><LF>
HeaderEnd<CR><LF>
LineStart<CR><LF>
EEEFFFGGG<CR><LF>
LineEnd<CR><LF>
LineStart<CR><LF>
EEEFFFGGG<CR><LF>
SubLineStart<CR><LF>
HHHIIIJJJ<CR><LF>
SubLineEnd<CR><LF>
LineEnd<CR><LF> |

Is "HeaderStart<CR><LF>" an actual fixed value?
If so, I'd use it as a Tag in a TDS message.
And I'd use "HeaderEnd<CR><LF>" as a group terminator.
And likewise with LineStart<CR><LF> and SubLineStart<CR><LF> and etc.
Then your model just has a group that represents the header, which contains your fields, and a group that represents a Line, with an optional subgroup for the subline.
There's a link here to a tutorial on fixed length messaging - that's not entirely what you've got here (but it *could* be). It'll at least get you moving in the right direction. |

Yes, "HeaderStart<CR><LF>" is a Physical value in the incoming message.
I have used HeaderStart as a Tag and <CR><LF> as the record delimiter. As you (mqjeff) said I have used HeaderEnd<CR><LF> as a Group terminator.
I am able to create Header Elements and Line Elements, if I add SubLine complex type as an element for the Line Segment then the message not getting parsed correctly...
You (mqjeff) have mentioned that

Please provide the link, let me check if I get some hints from that. |

Hi,
I had a discussion with Sending application and proposed a new structure as shown below.
HEADField1Field2Field3<CR><LF>
LINEField1Field2Field3<CR><LF>
SUBLField1Field2Field3<CR><LF>
LINEField1Field2Field3<CR><LF>
SUBLField1Field2Field3<CR><LF>
SUBLField1Field2Field3<CR><LF>
Where HEAD, LINE and SUBL can be used as the tags in the message set and they are fixed length tags.
If sending application agrees for this then I will go ahead with new structure.
Thanks for all your replies.
