Nested search or loop

[german_avanzato]

Hi Experts,

I'm trying to determine the price of a product.

For this task, I need to summarize the cost of all his components.

Something like this:

Product                Component               Cost    

A                              aa11                        12

A                              bb32                         1

A                              cda                           43

B                              sdf                           13

B                              bb32                         1

Cost product A = 56

Cost product B = 14

But in some case, one or more of the component of the product, is another product:

Product                Component               Cost    

A                              aa11                        12

A                              bb32                         1

A                              cda                           43

A                              B

A                              C

C                              aa11                         12

C                              sdf                            13

C                              ccc                            4

B                              sdf                           13

B                              bb32                         1                   

B                               C                             

B                              hfsdf                         315

B                              hgf1                         45

Cost Product A = 488

Cost Product B = 403

Cost Product C = 29

So in this case, first I need to determinate the price of C, after that; the price of B, and finally the price of A.

Not always is the same sequence, but always can be solved.

I don´t know how to approach to this problem in QV.

Any suggestion?

Thanks
