Urgent: problem with Change Outbound Delivery (VL02)

Hi guys,

When I give

Outbound Delivery >output >screen in transaction (VL02)

output type --zlab (Outbound Del. Label)

I get a information message called (zipe003)

after this I get Output could not be issued (Message no. VL086)

but when I give-- LD00 I get the correct output.

regards

Joseph
