You can use Screener with the Universe set to "Deals" and Asset Class set to "Bonds". E.g. the following expression retrieves bond issue deals with issue date last week, by non-government issuers headquartered in the UK.
screener_exp = ('SCREEN(U(IN(DEALS)/*UNV:DEALSBOND*/),TR.NIisECM=False,' 'relativedate(TR.NIIssueDate,LW), IN(TR.NINationHQ,"GB"),' 'NOT_IN(TR.NITRBCEconomicSector,"62"), CURN=USD)')ek.get_data(screener_exp, ['TR.NIIssueDate','TR.NIIssue','TR.NIIssuerPermId', 'TR.NIIssueType(Concat="|")','TR.NITransactionStatu', 'TR.NIProceedsAmtInclOverallotSoldAllMkts(Scale=6)', 'TR.NISecurityTypeAllMkt'])
