hi,
our pre-OpenERP system of filing customers and suppliers is using unique numbers for each supplier or Customer. There is no such thing in the Address book/contacts of OpenERP. Would you suggest to use tags for such a thing? or write a Module which adds a customer/supplier number entry to this?
An example. If I tag a Customer in our OE Address book now with it's customer number, will this tag still be with him through out an entire CRM process lead, oportunity, quotation, Sales Order, then a manufacturing order, etc ...?
We do not use all of these Modules yet, but I would like make sure I don't Set up a System of tags now, which will not 'stick' throughout all following processes,
