First Thanking all for your continuous support for your valuable comments.

I ran all the consistency checks,cleared all queues,CCR,CPP,/sapapo/sdrqcr21 etc. Still number not comming to RRP3.

would like to what would be root cause for this, how can fix this type of issue, Please comment and provide your valuable solutions.
