Change Attachment property CREATED_BY via code

For a complete list of my blogs regarding content management, please see here.

In our CRM social integration project we extract the picture of one tweet from twitter website  and store them in CRM system as attachment.

We are creating attachment in CRM via the approach described in this blog.

However, we found the Create by property for an attachment is always hard coded with sy-uname, even we explicitly specify the created_by property when calling

cl_crm_documents=>create_with_table. However our requirement is it should be filled by the screen name in twitter website who posts the tweet.

After some debugging I found the created_by property could only be modified after the attachment is created.

First I query all attachments of a given tweet:

Then I use FM SDOK_PHIO_PROPERTIES_SET to change the property

ENDLOOP.

I have put the code into a utility class and test it:

And that's done:

Never forget to activate internal mode, or else you will fail with an error message that created_by field is read only.
