Outbound delivery creation BAPI vs FM

[maqsood_ahmed]

Hi all,

I want to create outbound delivery for SO/STO/Subcontracting PO , i came across a BAPI BAPI_OUTB_DELIVERY_CREATE_SLS 

and FMs  RV_DELIVERY_CREATE and GN_DELIVERY_CREATE.

What flexibility will i miss out if i use the BAPI instead of FMs? Which one should i choose to implement the delivery creation action ?

Functionality is that the user selects few orders and chooses create delivery button.

Please read note 949074.

In standard, here are the bapis realesed for customer use.

bapi_outb_delivery_create_sls

bapi_outb_delivery_create_sto

bapi_outb_delivery_create_noref

From the BAPIs' name. it's easy to tell the functionality.

It's for SO-delivery, STO-delivery and delivery-without-reference.

The FMs (RV_DELIVERY_CREATE and GN_DELIVERY_CREATE) are the core function module for collective delivery creation. All the BAPIs, and standard non-dialog delivery creation tcodes will finally call one of the FMs to create delivery.

(Exceptions: VL01n, VL31n don't use the FMs. They have different program logic.)

RV_DELIVERY_CREATE:  It's for sales order delivery creation and it's ONLY for SO-delivery scenario.

GN_DELIVERY_CREATE: All the scenarios except SO-deliveries (STO-delivery, inbound delivery, post change delivery.....) should be created by this FM.
