Change mapping of webi work only once

Hello,

I'd to change the universe of a webi in BO with the get/post/put actions (raylight).

When I use the method to change the universe for the first time, it work pretty well. I can the see update on BO.

But when I tried to do it again, STATUS 404 appears. It's weird because I can still get information about this webi when I do :

GET - biprws/raylight/v1/documents/XXXXX/

My process :

STEP 1 : GET - biprws/raylight/v1/documents/AAAA/dataproviders/mappings?originDataproviderIds=DP0&targetDatasourceId=BBBB

STEP 2 : POST - biprws/raylight/v1/documents/AAAA/dataproviders/mappings?originDataproviderIds=DP0&targetDatasourceId=BBBB

STEP 3 : PUT - biprws/raylight/v1/documents/AAAA

About my BO Version :

SAP BusinessObjects BI 4.1 Support Pack 5

I searched on internet but i didn't find nothing.

Kind regards ,

Cyrille.
