link sales of former product to succeeding product

[Anonymous]

Hi there, 

I am trying to link sales on one product (A) to the sales of another product (B) where product (A) is the predecessor of product (B). 

Both of these products are maintained in the same table which contains ~ 30K records. 

A variant of this would be to add product (C) which is the successor of product (B). In essence all 3 products are the same, yet next iterations / improved versions of the 1st version. 

The sales for each of these products are maintained in a different table, which is linked by the product ID. Please see below examples of tables and the intended output.

Note that succeeding products B&C have multiple predecessors. This is not the norm, mostly it'd be one product succeeding one, but it does occur. 

the periods 4 and 8 show overlapping sales of the predecessor and successor. For these periods, the total value could either be the sum of the overlapping sales or the max for example of the predecessor / successor values. 

I've not listed the table which contains the sales. It's a 'typical' sales table though with product id, quantities and dates. 

So, in short I'm looking for a way for power bi to create the last table for me. (labelled 'intended output/ result). 

Thanks

Hi @v-xuding-msft 

thanks for your response. in the meantime I've had someone in our office help out. I can't explain really how, but I've got my successors correctly linked to my predecessors and are able to work with the output now. 

again, your intended help is well appreciated.
