Postscript Script Error: Error moving the Workflow Phase from Legal Review -->Supplier Draft or from Legal Review -->Draft

Hi Experts,

I am facing the following issue while moving the Workflow phase from Legal Review Supplier Draft or from Legal Review à Draft.

The following are the phases we currently have:

1. Draft.
2. Legal Review (Workflow Attached)
3. Supplier Draft
4. Waiting for Internal Approval.
5. Executed.
6. When I am moving the phase DraftàLegal Review . I am expecting once the document is approved, it should move to Supplier Draft. But its saying ‘Error Moving to Supplier Draft Phase, Supplier Draft is not a valid next or previous phase’. Same way when its rejected it should move to ‘Draft’ Phase.

When I checked the code by putting the log message in the Post Script, I found that the Post Script is getting executed twice. I am clueless why it’s getting executed twice.

In the post script for the 1^st time its saying the current phase is ‘Draft’ and in the next time its saying the current phase is ‘NULL’.

Following is the code for Post Script.

import com.sap.odp.api.common.exception.*;

import com.sap.odp.api.common.log.Logger;

import com.sap.odp.api.common.platform.*;

import com.sap.odp.api.common.types.*;

// The final step of the approval process moves

// the phase of the Project to Approved

// (if all approvals were made) or back to xxx

// (if there was a denial).

// Create a logger for messaging

logMsg = Logger.createLogMessage(session);

// If we are not approved, then change the phase backward

if (getApprovalStatus() != APPROVED)

{

home = doc.getIBeanHomeIfc();

home.upgradeToEdit(doc);

logMsg.setLogMessage("-----Current Phase is:"+doc.getCurrentPhase().getDisplayName()+"-----------");

Logger.error(logMsg);

if (!doc.getCurrentPhase().equals("Draft"))

{

try

{

home.changePhase(doc,"Draft");

}

catch(e)

{

logMsg.setLogMessage(e.toString());

logMsg.setException(e);

Logger.error(logMsg);

}

}

}

// If we are approved, change the phase forward

if (getApprovalStatus() == APPROVED)

{

home = doc.getIBeanHomeIfc();

home.upgradeToEdit(doc);

try

{

home.changePhase(doc,"Supplier Draft");

}

catch(e)

{

logMsg.setLogMessage(e.toString());

logMsg.setException(e);

Logger.error(logMsg);

}

}

logMsg.setLogMessage("Completed Workflow");

Logger.error(logMsg);

Looking forward for your help.

Thanks,

Ritik
