  Causes:
  
  
  Billing Block Reason: The contract has been assigned a billing block reason that prevents billing from being processed. This could be due to various reasons such as:

  Issues with the customer account (e.g., credit limit exceeded).
  Contract is in a status that does not allow billing.
  
  
  
  Contract Status: The contract may be in a status that does not permit billing, such as "Blocked" or "Inactive".

  Review the specific reason for the block and determine what actions are needed to resolve it.
  
  
  
  Resolve Issues:
  
  If the block is due to pending approvals, ensure that all necessary approvals are obtained.
  If the block is related to customer account issues, check the customer’s credit status and resolve any outstanding issues.
  Ensure that all contract terms and conditions are met.
  
  
  
  Change Contract Status:
