Hi there,
I need to add a custom report in post packing slip in place of sales packing slip, for that i attached my custom report using form setup > print management > sales packing slip > custom report
and to process that report i need to take salesid from sales edit lines as a parameter which I'm not getting how to achieve it.

After clicking on "Ok" my custom report will get generated but it needs that highlighted sales id as a parameter to process the report which I'm getting how to achieve it.
