ADS Printing: SY521 at PRE_DISP Act Hook on NC

Dear experts,

I am trying to set-up an ADS Printing scenario, where a label is printed after a concrete NC is logged. For that I have attached the SY521 activtiy as PRE_DISP activity hook on the NC, which has disposition group.

I followed the How-To Guide for SAP ME 6.1 printing ("How To Set Up and Use the SAP ME Printing Feature"), but there is no concrete reference to this scenario.

Does anyone have experience with such scenario? From my uderstanding, there are not many config steps necessary. But maybe I missed some:

1. define document
2. define printer as SY521 rule
3. attach document to material in material maintenance
4. attach activity hook in NC Code Maintenance

From this steps, I see as the complicated one the document settings, which I am attaching to the post.

Can anyone give hints?

Regards,

Andrej
