Lets assume we have the following use case:

The contract contains 100 contract lines. Contract fulfillment lines can be created using the 'Autocreate Fulfillment Lines' menu option. After that, mandatory purchasing attributes such as Procurement BU, Requisitioning BU, and Buyer must be manually defined for each fulfillment line, that is so time consuming repetitive actions. Is there any way to default these attributes somehow? Are there any available options for this, to automate it?
