Human Activity in SAP PO BPM

[Former Member]

Dear Experts,

Can we use human activity in SAP PO BPM?

Is it possible to use SAPUI5 page to cater this human activity?

Is it possible to use Java WebDynpro page to cater this human activity?

If not complex pages, atleast can we use simple human interation page that contains just the subject, description, approve/reject buttons?

We have SAP PO 7.4 SP9.

Thanks.

Yes Saravanan,It can be done using Java Webdynpro.

You can have approve/Reject buttons or any other button according to the requirement.

Refer the below document

Thank you Raghuraman.

When I followed the steps in the link you provided, at the last step for UI Generation [ after step 22 ], I get the error:

Task ui generation could not create component.

See error log for details.

How to check what has caused the error?

[former_member186851 · Accepted solution]

See the log and please post the exact error.

I guess problem with JDK

This is the error I can find in the NWDS .metadata folder's log file. I can't figure out the issue from this log.

Hi,

You get this error when you try to deploy the process?

[Former Member · Accepted solution]

No, i get this error when i tried to create webdynpro component. When I followed the steps in the link you provided, at the last step for UI Generation [ after step 22 ].

- Saravanan N

[former_member186851 · Accepted solution]

In the component select ->Webdynpro component and try once.

Raghuraman,

This issue got solved when we opened firewall config for PO server port 5xx13 / 5xx14 / 5xx04.

[former_member186851 · Accepted solution]

Fine Nagaraj,Please close the thread

[Former Member · Accepted solution]

Raghuraman,

In the lane's [ also human activity's ] potential owner, it could not list any user in the system. Any idea what the reason could be?

- Saravanan N

[former_member186851 · Accepted solution]

please post the screenshot..you will get it in the properties

[former_member186851 · Accepted solution]

you should assign as per the screenshot below.

Select the potential owners check box and give the owner.

And users should be created using userprofile.

[Former Member · Accepted solution]

Thanks. Thats what exactly am doing.

What I mean is:

In the Potential Owners --> Choose One or more UME Principles --> Choose --> Principles popup, I could not fetch any userid / role or group.

The userid I am using has got spml read/write permission as well.

- Saravanan N

[former_member186851 · Accepted solution]

Nagaraj have you configured "SAP as JAVA" system in Preferences.

[Former Member · Accepted solution]

Yes, SAP AS Java server is configured. I have already deployed the BPM without the human activity.

- Saravanan N

[former_member186851 · Accepted solution]

Apart from that no other settings Nagaraj.

You are getting an error or no user is displayed.

[Former Member · Accepted solution]

No error in the NWDS UI, just no user is displayed.

But in the NWDS logs, I find this error shown below. But as mentioned earlier, I have already configured SAP AS Java and deployed the BPM without human activity. Now, I am trying to add the human activity and trying to fetch the list of users to assign, but no user is fetched:

Any looping selected in any of the activity Nagaraj?

[Former Member · Accepted solution]

Raghuraman,

Yes, this human activity is one of the activities that are inside a for loop. Please note that the error message I posted above is at design time and not runtime.

[Former Member · Accepted solution]

Hi All,

I could not figure out what the issue is. As a workaround, I passed the "Potential Owner" in the data and assigned it dynamically by - Use an expression.

Thank you Raghuraman and Maximiliano for your inputs.

- Saravanan N

[former_member186851 · Accepted solution]

Nagaraj try assigning potential owner to entire process or to the whole lane..

[Former Member · Accepted solution]

Raghuraman,

I tried that as well, but didn't work. Same error.

Hi,

Is it possible to use SAPUI5 page to cater this human activity?

Yes.

Is it possible to use Java WebDynpro page to cater this human activity?

Yes.

If not complex pages, atleast can we use simple human interation page that contains just the subject, description, approve/reject buttons?

Yes.

Examples:
