Hints for S2S Submission
- Attachment Types: Streamlyne mirrors Grants.gov in the Attachment form types it uses to collect proposal attachments. To locate which Attachments Form is used, check in the S2S panel. As an example, this HHS proposal uses two forms to collect attachments:






- Attachments must be uploaded as flattened PDFs for ALL SPONSORS accepting proposal submissions via Grants.gov, unless otherwise instructed/allowed by sponsor. To flatten a PDF, print to PDF using your Print to PDF options (Adobe or Microsoft). Refer to these NIH Instructions, which give more detail on creating or testing flattened documents. https://www.era.nih.gov/files/How_to_Flatten_PDFs.pdf
- Special Characters: Grants.gov does not accept all UTF-8 special characters in file attachment names. Applicants are able to enter all special characters from the UTF-8 character set when submitting applications and information to Grants.gov. However, if the grantor’s system is not yet compatible with these special characters, the grantor system may produce garbled or missing text in the application. As a result, the application may be rejected. *In Streamlyne, this applies to the file name and any corresponding description for thatfile in both Proposal and Personnel Attachments sections. It is known that underscores (_) and hyphens (-) are safe characters to include, but ampersands (&) and slashes (/) are problematic. It is best to exclude any special characters, though.
- Allowable Greek Characters and Where as of December 2025

- File names for attachments cannot be more than 50 characters for all Grants.gov submission. Some specific sponsors have limits which are lower (USDA Capacity grants have a 45-character limit).
- Sponsors sometimes require a different Grants.gov (R&R) budget form for subs than for the prime/lead organization. Iowa State’s budget will generate from the Streamlyne budget, but the sub budgets are uploaded using the correct R&R budget form, which is embedded in the Subrecipient Budget Attachment Form in the S2S Forms Panel. Please refer to the Entering Sub Budgets in Streamlyne Tip Sheet, found on the OSPA Streamlyne page, for step-by-step instructions.
- If the S2S Lobbying form is generated by the answers in the Questions tab (rather than this form being filled in and uploaded separately), the registrant and the identity of the individual performing the services will need to be NA, which can be found in the Streamlyne address book as ID# 106976. This will need to be selected for both fields, or Grants.gov errors will be generated.

- Some sponsors require a full nine-digit Postal Code for the PI/Key Persons, and some may want a Fax number. It is recommended that the Person Details are checked to ensure that these fields are complete. These address items will be pulled into the SF424 form as well as the RR Senior/Key Person Profile (or other forms depending on the sponsor). If the sponsor does not have the same requirements as Grant.gov, these errors may not be generated until after submission.

- Change/Corrected Application

- The Prev. Grants.gov Tracking ID is generated in the Sponsor & Program Information field.

- The Original Institutional Proposal ID is generated in the Institutional Fields Conditionally Required:


- External Person in ISU budget
- Highlighting of Invalid Special Characters

- The warning below is generated with NIH S2S submissions. It has been checked by Streamlyne and does not cause submission issues. This warning can be ignored.

- PHS Human Subjects form



- The Data Management and Sharing Plan is required with all research proposals unless otherwise directed by the FOA. This document is attached under PHS Research Plan Other Plans:

- Effort for the PI must be entered for each budget year.



- AFRI project type form must be uploaded as a fillable form (not flattened) which is an exception to the standard grants.gov rules. To ensure you are uploading in the correct format, follow these steps:
- Download a fresh copy from Streamlyne by selecting and opening the AFRI Project Type form.

- Complete the form by selecting the appropriate boxes to match the project’s type.
- Save it to your computer without changing the name
- Upload it to the User Attached forms section by selecting Choose File and selecting Add. A description can be added.
- In Streamlyne, both a Project Abstract and a Project Summary Attachment Type are available as Proposal Attachments. In addition, there may be alternative locations to attach a Project Abstract or Summary in these proposals, such as in the S2S section of the Questions Panel. When the number of locations available for upload, or the labeling of the Attachment type doesn’t match the FOA, determining how to include this/these documents in a DOD S2S can be confusing. This has been a known issue in DOD proposals but could show up in other types of submissions.
