Problem in IDoc administrative segments while converting IDoc text to IDoc xml

Hi Experts,

I am using file channel in PI for converting IDoc flat file into xml. I am using the standard module SAP_XI_IDOC/IDOCFlatToXmlConvertor.

The problem is with IDoc administrative segment which is 63 character long as described below:

Segment name (30) + SAP client (3) + IDoc number (16) + number of SAP segments (6) + Number of the hierarchically higher SAP segment (6) +

+ Hierarchy level (2)  = 63 chars.

Segment name, SAP client, IDoc number is fine. But I need to understand the functionality of 4th and 5th part in the above distribution.

number of SAP segment (excluding the header) --> If I generate an IDoc flat file, this 6 char field is generated as 000001, 000002, 000003 and so on ..

So I expected that same way I could keep it in the IDoc text file which I have to convert into IDoc xml but this is creating a problem. I am not sure what should be correct pattern if I wish to create a file same way as I got from the standard output for IDoc text.If I keep the fields as 000001, 00002, 000003,

I get an error that IDoc could not be parsed properly by the sender channel.

For example, the following file is not read by the channel

If I keep some random values for 000001, 000002,000003, 000004 ...in above file (say 000001, 000004, 000006, 000009...), then the file is processed successfully (Idoc text to IDoc xml).

Am I doing something wrong here ?

Thanks,

Ravi.
