IDOC Outbound Segment Extension Does Not Show

Hello Experts!

I created an extension (ORDERS05EXT) with reference to basic type ORDERS05 for message type ORDERS.

In the ORDERS05EXT extension, I inserted a new segment type ZE1EDC01 as child to parent segment E1EDC01.

NACE:

EF (Purchase Order) > ZEDI (Output Type) > RSNASTED > EDI_PROCESSING (Routine)

FM: IDOC_OUTPUT_ORDERS

Basic Type: ORDERS05

New Message TYpe: ZORDERS

Extension: ORDERS05EXT

Object: BUS2012

Partner profiles properly set-up, CMOD project is activated, all new segments and message types are released.

Problem:

In ME29N

Purchase Order: 4300000419 (for example)

Using Message Type: ORDERS and Basic Type ORDERS05,

E1EDC01 shows with the other segments - green status in WE02 - OK!

but after adding my message type in the outbound messages in partner profiles,

Purchase Order: 4300000419 (for example)

Using Message Type: ZORDERS, Basic Type ORDERS05, Extension ORDERS05EXT,

E1EDC01 with my new segment ZE1EDC01 DOES NOT SHOW, but some segments are still populated - green status in WE02 - NOT OK!

Any ideas why this is happening?
