CREATING CUSTOM ORACLE WORKFLOW USING AME JANUARY 27, 2015 | EFE AVŞAR | LEAVE A COMMENT
Oracle Approvals Management (AME) had rst published over ten years ago, and also big question is “Why isn’t it so popular”. I think this is all about supporting unnecessary extra extensibility which is not required for traditional approval processes. AME includes many advantages for more exibility/extensibility/functionality on approval processes. If we would like to check some of these advantages; you can create custom transaction types ,approval groups , approval types. These are de nitions called rules, attributes, conditions, approval groups, action types. Most featured functionality that AME provides us is action types like paralel or serial voting. You can use approval types like consensus (all approvers have to approve to end approval process) , rst responder wins ( rst approver nishes all process). And you can de ne these approvers dynamically , It supports; HR Organization Hierarchy Roles Users Most important one: your custom approval processes with your custom rules For further information about AME you can check these document for AME implementation : Metalink Note 336901.1 and Note 282529.1 In this case, We created a simple custom WF and PL/SQL package for AME rules and noti cation process. Custom WF contains two processes a main and a subprocess;
In main Work ow process we call AME process with only a return type approved or rejected. So! We are focussing only AME sub-process in this practice . Now check two notifcations and what function look like ;
These three functions use following package ; 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18

What we had done in package above is simple ; in getNextApprover : we used AME engine to nd existing situation of our noti cation and approvers. Then we created a role for the current approver then set it as noti cation performer . in updateAmeWithResponse : we updated current noti cation status using AME engine(ame_api2 package) and control if it is in timeout period or not , also if it is nal approver of AME approver group. Now we begin to start this WF process from this following package below for Orders which have holds (startApprovalWF procedure) . We can log this process (insertLog procedure) . We set document type attribute to set a custom OAF page for noti cation content. We also have custom business rules like timeout for noti cation process just in case our approver doesn’t give a response to it . (getTimeoutDay function). In this case our AME transaction type has the same name as Work ow item type . Package ; 1 2 3 4
