How to edit 'Modified By' field from MDM?

[Former Member]

Hi All,

I hope this message finds you well. Coming to my query.

We have developed portal application on MDM repository in web dynpro java. In which there are two fields which are automatically filled (not editable) based on the user id. PFB

In our case, these fields are populated in two ways. 1) user id (the one who create/edit the record) 2) WebService user id which was assigned to web services in NWA.

Sometimes the record is automatically updated with the use of web services, in that case 'Mofified By' field is populated with web service user id.

Can you please help me on how to manipulate this field so that the field is populated with whatever i assign? Is it possible dynamically?

And how does the automatic population works? By using logon id? Can anyone explain me how it works?

Please let me know if you do not understand the query. Any help will be highly appreciable?

Thanks & Regards,

Manoj

Well i don't think you can edit those basic fields by your self. You could either let the webservice forward the ticket so that the logged on user is set or you could just create a custome field "modified by" where you could pass a string (e.g. UserId).

Hi Tobias,

Can you elaborate on the part 'let the webservice forward the ticket so that the logged on user is set'?

If the standard web service forward the ticket, will the logged on user be automatically set? How is it done?

Thanks & Regards,

yes,

when you generate the ws, there is an option to accept logon ticket. you have to tick that checkbox

Yes, as Jun mentioned you can set this on design time generation of the service. Take a look at this -->Defining Security Settings - SAP NetWeaver Master Data Management (MDM) 7.1 - SAP Library

Hope this helps,

Thank you both.. One more question.

What if the webservice were used in BPM worlflow? It requires no users, right? Then in that case what would happen?

[former_member191044 · Accepted solution]

Then the SAP_BPM_Service user would trigger that but i don't think this user will have permissions on your MDM Repository so it probably would lead to an exception.

are u using the ws generated by mdm ws generator?

how can it require no user? you want to populate the correct user,  and you don't ask for user account to run the ws, you are making your life hard......

Say this application is for privileged client. We do not want to ask them to provide account credentials for every WS that we use. Except for SSO. So that they will concentrate on what-needs-to-be-done rather than providing credentials for WSs.

We created a user in portal (say Web_Service) as well as in MDM repository, and we configure this for every web service in NWA as a custom value.

then what is your what-needs-to-be-done?
