Hi Guru's,

I have a requirement wherein we want to create a contract from opportunity as an event based integration and once the contract is created the requirement is to update the bill plan and revenue plan in each of the contract line. 

For updating the bill plan and revenue plan in the contract lines we are using multiple for-each loops but the values in the bill plan and revenue plan ID are same in all the lines.
