urgent: Slip output not trigger out

Hi experts

HOpe to get your help

We have two output type zwa1/zwa2. Now we found zwa1 could be triggered out by mb1b but zwa2 can't.

we have set NDR as big X and ND9 as the user group. in omj4 ,we setup plant locaiton and user gorup with printer.

Now If I set locaiton with output type with zwa1, when I do mb1b ,zwa1 could come up in message

but if I set locaiton with output type zwa2 , there is no message output trigger out.

I check the output type, it seems they both use plant/location/user group combination.

ANy adivce why zwa2 can't come up ?

Thanks

Alice
