Composite Provider Delta in SAP BW 7.4

[Former Member]

Hi everyone!

I have a task of creating a DTP with delta extraction from composite provider to ADSO, composite is a union of 3 ADSO with infocube template.

help.sap.com says:

In delta mode, the DTP supports CompositeProviders (object type HCPR) as sources if they are made up entirely of InfoCubes or of DataStore objects (advanced) that are modeled like standard InfoCubes or standard DataStore objects (classic). The target of the DTP must be a DataStore object (advanced). A combination of InfoCubes and DataStore objects (advanced) as PartProviders of a CompositeProvider is not supported for DTPs in delta mode.

But in my DTP data extraction mode is greyed out.

Any help with creating a working delta will be appreciated.
