Hi Raj,
Free selection tab is sort the payable line items like document type ,doc date fiscal year,posting date and so on.
In free selection tab 2 option are available
1.Inculde
2.Exculde
For example you have 100 payable open item with you in that you have to pay only those are related with particular business area.in this senario you can use free selection option and select that field and give the value of business area.system will pay only this business related open items only.
Same senario but if you dont want to pay same business area related payments select the Exculde check box.system avoid the payable item in this payment run.
May be this information is useful to you
If you have any doubt feel free to ask
Regards
Aneesh
