append for xml

[Former Member]

Dear Experts,

Is it possible to use append mode for xml files. Each time an idoc comes it should get appended to the xml .

Thanks,

We had a similar requirement & we had to do it as a 2 step process.

Out requirement was : Sending System-> IDOC; Receiving System-> XML message (not an IDOC) but this XML will contain multiple records, one record for an IDOC.

2 Adapter modules are required.. 1 adapter module(in receiver comm channel) to strip all the XML tags when the data is being appended to a temporary file.

When you know this final file has to be transferred to target system, we pick this temporary file (& using another adapter module in Sender comm channel create XML root tags) & create the required output file..

If your requirement is to append IDOC-XML's, collecting them at source is the best solution.

You can use BPM to merge them.

Saying you pick up the target xml file, get the new xml file and merge them to new target.

No,in that case you will have multiple XML declaration tags within the same XML file which is Invalid XML.

Hi Amir,

The scenaro is this. Idoc comes from sap at regular intervals. It has to be collected into one fixed length file. But in the reciever append is not allowed. So what are the options ?

Hey

You have 2 options

First is to use BPM:

You can collect all the IDOC's in BPM and after a certain time period send them all to the receiver system.

Second is to collect IDOC's in SAP itself:

IDOC's will be collected on the file system in SAP itself and will be send as a batch(XML file) to PI.This is a much better approach in your case.

Hi Amir,

you could append in a temporary file, which you transfer frequently to target folder in other process. Easy development but may be not the most elegant solution.

As alternative create a business process, where merge the messages and send them finally to the target folder. This would be the standard, but a little bit more complex to develope and with less performance.

Hey Udo

>>you could append in a temporary file, which you transfer frequently to target folder in other process

But at the end of the day,it will be an XML file with multiple XML declaration tags,wont that be syntactically wrong as per XML standards?

Thanks
