T/code OMJ4

Dear all,

I want to print mat doc via network printer instead of frontend printer.

I have do the necesary configuration in OMJ4.

However, when doing MIGO for a non stock material, no mat doc was printed out. As the material was non stock, no storage location was needed during MIGO.

I tried setting up a conditon in OMJ4 without entering the storage location but the printout still did not come out.

My questions :

a) Is it because since there is no storage location being stipulated, SAP is unable to locate the network printer to do the printout?

b) Is the storage location in OMJ4 mandatory?

Please advise.
