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 _______________________________________________ rules-users mailing list rules-users(a)lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users

Hm, that was my first thought too - but doesn't such a rule fire 2 times if there are 2 facts (one with 7000 and another one with 7001)? Because this would be wrong: if both facts exist, the rule should only trigger once, with the 7001 fact. The 7000 fact would need to be ignored in that case. Probably I wasn't clear when I stated my problem :-) Sorry Thanks! -- CU, Joe _______________________________________________ rules-users mailing list rules-users(a)lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users

Just to make sure that I correctly understood it: The "roleCd == "7001" && > $rcd" part of the last pattern could also be written as "roleCd == "7001" && != $rcd". That && > is just to make sure the last pattern matches for the 7000 fact if there is a corresponding 7001 fact.

Thanks again! -- CU, Joe _______________________________________________ rules-users mailing list rules-users(a)lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users
