Quote with crmid and quoteid = 0

[joebordes]

If you don't need the quote, set the DELETED column to 1 in vtiger_crmentity (and vtiger_crmobject). That should hide it from everywhere

If you need the quote, then you will have to increment the vtiger_crmentity_seq and use the number to set it in all 4 tables (at least)

vtiger_crmentity
vtiger_crmobject
vtiger_quotes
vtiger_quotescf

and the vtiger_quotes bill and ship if they exist (I don't remember)

let us know how it goes
