If you change budget, key person, and/or performance site data in one of the linked subawards, Cayuse Proposals will automatically update that data in the prime as well.
Subawards with Empty Budget Periods
Cayuse Proposals expects all Subawards linked to a Prime to have the same number of budget periods as the Prime (and the same dates). When you import a linked subaward or link a subaward to a prime, it will bring up a dialog asking you to match up the sub's budget periods with those of the prime.
Any empty periods will be marked as inactive, and the others synced according to your assignment, so there is no need to fill in any "blank" or "dummy" periods in your subaward.
Note: NIH no longer permits subawards that do not have the same number of budget periods as the proposal.
Using Subaward Worksheet Rows
The table on the Subaward Budget Attachment form also operates as a Subaward Worksheet, to which you can add a row or rows without a detailed Subaward behind it. You can then fill in subaward numbers manually.
To add a new Worksheet Row, click the 
button at the top of the Subaward Budget Attachment Form and scroll down and click the plus sign to the left to fill in cost data for each budget period (the total is a calculated field and can't be filled out directly).
The worksheet row will be listed on the Subaward Budget Attachment Form in a similar manner to a true subaward, but because it doesn't correspond to a separate subaward proposal, there is no link to click, and the unlink button is replaced by a delete button:
Worksheet rows are useful for what-if scenarios, placeholders, and flowing numbers into modular budgets. Proposals using modular budgets cannot also submit detailed subaward data, and by using a worksheet row, the appropriate budget data will flow from the from the table into the modular budget, where the Subaward IDCs can be excluded for determining the direct cost modules.
You can also use worksheet rows to attach additional subaward data when you're reached the limit of allowed subaward budget attachments. Depending on the form that is provided with your opportunity, you may reach this limit at 10 or 30 subawards. If your proposal exceeds this limit, you can create worksheet rows for the additional subawards so that you can calculate costs correctly. In this case, you would also attach the subaward details as part of the Budget Justification.
Warning: A Worksheet Row is not a substitute for a Subaward! Neither Grants.gov nor NIH can extract information implied in a worksheet row. For instance, NIH needs to know what the Indirect Costs are for the subcontract in order to check your proposal against funding limits, and they can only get this information if you fill out a subcontract.
