The search is running on communications with a filter for Tax Invoice and Email to restrict results

thanks, i have added my vote to the enhancement

I have checked that answer and i do have the additional accounts box ticked, the account I am missing is an expense account, so dont think that would change it

Yes i was using a sublist group, but i have subsequently found an enhancement request to enable these fields in the sublist fields, so looks like not currently possible

yes at the moment given the restriction to have locations at a single subsidiary level i am going to create a new location, i will then need to transfer all of the existing transactions from the current to the new location for one of the subsidiaries, so far have not found a script or process that can automate this
