## Retry-only Process

RETRY_ONLY is the internal name of the Retry-only error process. The purpose of this error handling process is to alert an administrator when an error occurs in a process and prompt the administrator to retry the process in error.

#### 'Initialize Error' Function Activity

The Initialize Error activity calls a PL/SQL procedure named WF_STANDARD.INITIALIZEERRORS. This procedure determines if the item type of the errored process has an item type attribute defined with an internal name of WF_ADMINISTRATOR. If it does, it sets the performer of the subsequent notification activity, NTF with RETRY Only, to the role stored in WF_ADMINISTRATOR. If it does not, the subsequent notification activity remains set to the default performer, System Administrator.

By checking for an item attribute called WF_ADMINISTRATOR in your errored process' item type, the Initialize Error activity lets you specify who you want a notification to be sent to in the case of an error in your specific process without modifying the error process.

For example, suppose you have a requisition approval workflow and you want the purchasing administrator, not the system administrator, to resolve any problems that arise from this workflow. You can define an item attribute called WF_ADMINISTRATOR in the item type that owns your requisition approval workflow and set WF_ADMINISTRATOR to the purchasing administrator's role, which may be PO_ADMIN.

#### 'NTF with RETRY Only' Notification Activity

The NTF with RETRY Only activity sends the Retry As Only Option message to a performer (the System Administrator or whatever role is stored in your item type's WF_ADMINISTRATOR item attribute). The message indicates that an error has occurred in the specified process and prompts the administrator to retry the activity that errored. The error process then transitions to the Retry function activity and ends the Retry-only error process.

> Note: The notification message's embedded URL link displays the process in error in the Workflow Monitor with full administrator privileges. You can perform actions such as retrying, skipping or rolling back part of your process within the Workflow Monitor to resolve the error.

The subject and body of the Retry As Only Option message are as follows:

    Subject: Error in Workflow &ERROR_ITEM_TYPE/&ERROR_ITEM_KEY

    	&ERROR_MESSAGE

    Body: An Error occurred in the following Workflow.

    	Item Type = &ERROR_ITEM_TYPE

    	Item Key = &ERROR_ITEM_KEY

    	User Key =&ERROR_USER_KEY

    	Error Name = &ERROR_NAME

    	Error Message = &ERROR_MESSAGE

    	Error Stack = &ERROR_STACK

    	Activity Id = &ERROR_ACTIVITY_ID

    	Activity Label = &ERROR_ACTIVITY_LABEL

    	Result Code = &ERROR_RESULT_CODE

    	Notification Id = &ERROR_NOTIFICATION_ID

    	Assigned User = &ERROR_ASSIGNED_USER

    	&MONITOR

The NTF with RETRY Only notification activity has a dynamic timeout value assigned to it. It checks the item type of the process in error for an item attribute that has an internal name called ERROR_TIMEOUT. ERROR_TIMEOUT must be an attribute of type NUMBER. The Workflow Engine interprets the timeout value of this attribute as a relative offset from the begin date of the activity, in the unit of MINUTES. If ERROR_TIMEOUT contains a null value, a value of zero, or is not defined at all, then NTF with RETRY Only has no timeout.

#### 'Error Still Active' Function Activity

The Workflow Engine initiates the Error Still Active function activity if the NTF with RETRY Only activity times out.

The Error Still Active activity calls a PL/SQL procedure called WF_STANDARD.CHECKERRORACTIVE. The purpose of the Error Still Active activity is to determine whether the errored process is still in error before continuing with the error handling. If it is, Error Still Active returns TRUE and the Workflow Engine transitions back to the NTF with RETRY Only notification activity to send another notification to the administrator. If the errored process is no longer in error, this activity returns False and the error handling process ends, as modelled in the process diagram.

#### 'Retry' Function Activity

The Retry function activity executes the PL/SQL procedure WF_STANDARD.RESETERROR to clear the activity that was in error and run it again. This procedure calls the WF_ENGINE.HandleError API to rerun the activity.
