I have a requirement to extract a structure of WBS from ECC into BW. In BW, there will be authorizations setup on this hierarchy. These authorizations will use the technical node IDs as reference.(lets say untill level 4 out 7 of the hierarchy).
Therefore, with any change made to the structure in ECC (adding new nodes ) until level 4 , upon extraction in SAP BW, the technical reference of ALL nodes in the hierarchy will get updated.
What I would like to achieve is a only a delta transfer of the hierarchy after the initial load. So that there the entire hierarchy does not get refreshed each time.
How do I achieve this? Is this possible?
