Already uploaed to SVN and modified Suppliers.php to use it.
Please check if it's according webERP rules (I hope so). If OK, I will continue with customer scripts.
Regarding the address fields names, we could set them up in SystemParameters, so each installation could have the correct ones to their needs. Currently, having Address 1,2,3,4,5 it is not clear enough for most users. Our DB has many changed fields (City name in field 2 or 3 or 4). Our final users say it is not clear enough, and I do think so. So if it's a parameter, everybody will be happy.
Sorry, I'm having problems commiting changes...
So files are attached here, until I fix the commiting problem.
