Error in bapi BAPI_OUTB_DELIVERY_CREATENOREF

Hi,

I want to create a delivery without reference i.e. tcode = VL01NO

I am using bapi BAPI_OUTB_DELIVERY_CREATENOREF.

But I am getting an error " Copying is not poss.because an entry is missing in Table TVCPL: ZLOR"

ZLOR is my delivery type to create delivery without reference.

Manually I am able to create delivery w/o ref in VL01NO.

However bapi is giving me an error.

I enquired with the functional, TVCPL check shouldn't happen as it is used to fetch when delivery is created without reference.

Please help.
