Why a contract is not generated for an amendmend operation on Salesforce.

[Vishala]

Question:

On an amendment quote, clicking on contract button, contract is not getting created for the amendment operation.

[Vishala · Accepted solution]

Answer:

For this particular case, 

The Quote parameter (which is a lookup field) for the associated master contract of the
 amendment quote (Contract.SBQQ__Quote__c) is somehow NULL for this case. This is a 
required parameter for the amendment to work properly. This value cannot be NULL

Once the value fixed on the quote, amendment process worked fine.
