IDOCXmlToFlatConvertor using segment type instead of segment definition

Hi,

We are migrating a PI7.1 to a PO7.5 (single stack).

In the old PI we were using an abap mapping to convert idocs to flat files.

So, we substitued tha abap mapping with the adapter module SAP_XI_IDOC/IDOCXmlToFlatConvertor. The issue is that the ABAP mapping was sending the segment types to the receiver system, and the IDOCXmlToFlatConvertor is sending the segments definitions.

For example:

Old abap mapping ->

E1EDK01 At start of the line.

Adapter module ->

E2EDK01005

Is there any option to change the adapter module to use segment types instead of segments definitions?

Thanks
