I have configured these below configuration in my mikrotik core router but the problem is here
my outgoing traffic is going properly based on the PBR but my incoming traffic is not coming properly
based on my incoming filter rule.Sometimes it's coming properly but sometimes it's not coming
properly .

Sometimes my IDEA traffic is coming on VODAFONE and sometimes VODAFONE traffic is coming on IDEA link

What exactly are you tryig to achieve? If you need simple load balancing, maybe you should try advertising all 4 pools to both Voda and Idea and using prepend to balance traffic. Maybe if you explained your requirement in some more details, we could help.
