Flat IDOC structure on adding Zsegment to ORDERS05

Hello All,

My requirement is to extend outbound IDOC for ORDERS05 as follow

-->E1EDP01 (item level)

----------> under E1EDP01 segment add new custom segment.

In order to achieve this, I have completed the needful steps in WE30, WE31, partner profile maintenance, etc.

I have added below logic in EXIT_SAPLVEDC_002

IF int_edidd-segnam = 'E1EDP01'.

CLEAR int_edidd.

int_edidd-segnam = 'ZEX_ORDERS05'.

int_edidd-sdata = ls_orders05.

APPEND int_edidd.

ENDIF. " At this point, INT_EDIDD is appended with custom segment details.

However, when IDOC is generated, the structure is flat.

I have tried searching in the forum but none of the suggestion worked. Your help will be greatly appreciated and the right answer would be rewarded.

TIA.
