BOPF Transient Attributes

[Former Member]

I have one question though that I am not able to figure out; probably I can get some thoughtful insights. In regards to BOPF, SAP provided transient attributes don’t get persisted to the database rather they are volatile in nature that get loaded into the context during the run-time; the BOPF framework takes care of this loading and syncing. But the question that baffles me if they are not stored at the DB level; how are they getting retrieved? Are they loaded from the buffer? What is the high-level mechanism that is working behind the scenes? Thanks. Regards, Tanmoy

Hi,

You have to fill the attributes yourself with your own abap logic.

Use Determinations for that.

Hi Tanmoy,

The high level mechanism behind filling of transient field is Determination.

In determination, we have 2 types

i) Persistent - Can change the persisted field values => Exclusive Write

ii) Transient - Can not change the value of node => Read Only

When we create transient determination using Business Object Builder, we have to choose 'Fill transient attribute of persistent node' option.

It does not look like we are moving in the right direction. Thanks.
