BTE 1120 for posting to controlling

Hello,

I have been working on activating BTE 1120 to modify the WBS element before the document is posted. I have been able to successfully modify the value on field PROJK and it is shown in FB03, once the document is posted. However, it looks like the integration with Controlling is not catching my change. The line item posting to the WBS I forced using the BTE is not displayed in the controlling document or visible in report CJI3.

Has anybody had the experience of using this BTE to modify CO objects like cost centers, WBS, etc..? Have your changes been successfully reflected in the CO document?

I have read several discussions related to the use of this BTE, but no one has really discussed its integration with CO.

Thanks!

César.
