RV_DELIVERY_CREATE issue

Hi guys,

1.

Is it possible that RV_DELIVERY_CREATE could generate an item text (Delivery Item)? Well I know there's CREATE_TEXT, SAVE_TEXT to STXH. But in our case, we have Sales order as reference and use it in RV_DELIVERY_CREATE like VBUP. Do you think the sequence of the item texts refers to the sales order table VBUP?

2.

I was also wondering why child items have to set the line items first to 999001/999002 instead of 00021/00022, when passing it to RV_DELIVERY_CREATE?

3.

Can we still use RV_DELIVERY_CREATE for MySAP Version or we need to change the function module?

Need your urgent response..

Thank you..Points will be given.
