Hi all!
Have an issue, need to create some groups and perform aggregation based on the matrix below:

For example Group 1 will aggregates the data with BU number 6888+1411+1360-4920-1402-1310 etc.
Same for Groups 2,3,4.
In the end i need to have four separated aggregated tabs: 3911,3925,2934,3986 based on the coefficients above.
Hope it is not too confusing. Thanks for your help!
