Finding Common list of Vendors for selected Plants

Question

Dear All,
I need a report where user will select Plants and for those plants I have to show only those vendors which are common to all plants. I want this to be done in Bex or using BO WEBI Report.
I have created a Query which has Plant, Vendor and a key figure as No. of Vendor. It gives me data something like this.
                  Plants
Vendor       P1      P2     P3      P4
V1               1         -       1        1
V2               -         1       1        -
If I select P3 and P4, result should be V1. If I select P1, P2 it should not give me any vendor as it has no common vendor.
Your help is appreciated.
Thank you.
Regards,
Prakash Sahu

hi,
Create a CKF on top of No of vendor such that for the example provided by you it takes the plant values from variable and then populate such that in below case when P3 & P4 are entered it returns a value1 other wise 0 (boolean logic).
Then on top of it write a condition that it should show only those records for which the CKF is showing non zero value.
Plants
Vendor P1 P2 P3 P4
V1 1 - 1 1
V2 - 1 1 -
If I select P3 and P4, result should be V1. If I select P1, P2 it should not give me any vendor as it has no common vendor.

Arvind.
