link « Organize Delta Initialisation » does not diplay in DataMamager

Hello Experts,

I would like use delta initialisation to retrieve data from BW cube to BPC.

When I go to the DataManager -> Organize, I cannot see the link « Organize Delta Initialisation» but just 2 links« Organize Package List » and« Organize Package Link List ».

Note : for the releases

SAP BW :  7.31 SP05

SAP BPC NW 10 : SP05

EPM Add-In :  Version 10.0.0, Build : 5102

Does someone have any idea to display this link « Organize Delta Initialisation» ? Why I do not see this link ?

Thank you in advance.

Regards,

Son
