[rules-users] Binding a variable with an OR pattern

Hi all Trying to do the following: as one pattern of a rule, I want to bind a variable to a fact with code "7001", or (if such a fact does not exist) to one with the value "7000". Until now, I haven't been able to formulate this in one single rule, as simple as it sounds - probably I'm just overlooking something basic ... Currently I have 2 rules: rule "R7012: UpdateInstrumentsIssuerFrom7001" agenda-group "TRANSFER_TO_LIVE" salience 100 when sirole : SourcingInstitutionRole(sourcing_Status == SourcingStatus.IMPORTED, roleCd == "7001" ) insti : Institution ( ids != null, ids.sspFI == sirole.institutionProviderId ) instr : Instrument ( ids != null, ids.sspFI == sirole.providerId, issuer.issuerId != insti.id ) then tlog.info("Modify issuer of {} to {} (from role code 7001)", instr, insti); modify (instr) { issuer.issuerId = insti.id } end rule "R7012: UpdateInstrumentsIssuerFrom7000" agenda-group "TRANSFER_TO_LIVE" salience 100 when sirole : SourcingInstitutionRole(sourcing_Status == SourcingStatus.IMPORTED, roleCd == "7000" ) insti : Institution ( ids != null, ids.sspFI == sirole.institutionProviderId ) instr : Instrument ( ids != null, ids.sspFI == sirole.providerId, issuer.issuerId != insti.id ) not SourcingInstitutionRole(sourcing_Status == SourcingStatus.IMPORTED, providerId == instr.ids.sspFI, institutionProviderId == instr.ids.sspFI, roleCd == "7001" ) then tlog.info("Modify issuer of {} to {} (from role code 7000)", instr, insti); modify (instr) { issuer.issuerId = insti.id } end This seems to work, but I would have expected that it should be easy to do this in one single rule !? But I just can't come up with a rule that does what I want... How would I formulate such as rule? -- CU, Joe
