Cannot process a Fixed Field Length file using the File Adapter (Sender)

Question

Hi -
I have checked throughout these posts and blogs but I still have not been able to find a solution to my issue.  When using the File Adapter (Sender) I get a Conversion initialization failed with "xml.keyfieldName", no value found.  Why would I require a key field when I am using fixed field lenghts?  The file is comprised of 2 structures - 1 header and multiple details (see below).  There are no key fields in the flat file that I would be able to use.  Any suggestions?

The File Adapter is configured as follows:
Document Name = Rfchke00
Document Namespace = 'my namespace'
Recordset Name = Rfchke00
Recordset Structure = Dtachkh,1,Dtachkp,*
Recordset Sequence = Ascending
Recordsets per Message = 1
Key Field Type = String (Case-Sensitive)
Dtachkh.fieldFixedLengths = 15,25,8,6,1,8,8,8,15,3,31
Dtachkh.fieldNames = F1,F2,F3,F4,F5,F6,F7,F8,F9,F10,F11
Dtachkh.processFieldNames = fromConfiguration
Dtachkp,fieldFixedLengths = 18,13,13,35,15,3,8,2,21
Dtachkp,fieldNames = F1,F2,F3,F4,F5,F6,F7,F8,F9
Dtachkp,processFieldNames = fromConfiguration
Thanks,

Hi,
you can use the module from which u can convert your structure to
H011000390 Customer Americas 20080605164317 000000000000000800000008000000000016000000
D12345678 100500 100500 Supplier 1 0000000000030000002008040400
D12345678 100501 100501 Supplier 2 0000000000052000002008042100
Please note the extra H,D in the struture added by the module.
You can then use them as your key fieldValues.. The module should be deployed in Visual Admin and then can be used in the Module tab of your adapter CC
While writing the content conversion after that please dont forget about the added new characters
Please note also that i can find that the word supplier kept repeating in all the Dtachkp records
Please use that
Also if you feel that the field is of 13 characters and that would cause a problem dont worry... create a dummy field eg split tht 13 to two fields and use the common one as key field Value and identifier... as i see in ure case its like 500 Supplier , 502 Supplier . u can split the first 4 char and the remaing 9 char are key field value.
try this out
