KE4I +/- Settings Issue

Hello All Experts,

I am facing an issue in KE4I +/- signs in COPA, went through this thread below link –

http://scn.sap.com/thread/1898438

One of the answers by Ajay sir says below comment -

Suppose you have Cond Type ABCD and PQRS in SD... You have mapped both of them to same value field VV100 in KE4I....

Let’s assume ABCD has a +ve value in the SD Pricing procedure (100 USD) and PQRS has -ve Value (-20)... In this case,

1. a. If you don’t tick +/- indicator in KE4I - The value posted in VV100 will be 120 instead of 80

1. b. If you tick +/- indicator - Then it will be 80 USD in VV100

I have doubt as below –

1. If I have single condition type assigned to single value field how this +/- will work if I TICK this? (Can someone provide an example)
2. What is the driving factor that which condition type should TICK +/- for ABCD or PQRS condition type?
3. I have case where I have 6 different condition types assign to same value fields and they are randomly TICKED +/- in KE4I what does that mean then?   

Sadly this making me very much confused couldn’t measure the system behavior. Expert’s guidance will be very much helpful on this.

Thank you.

Regards,

Sharu.
