# How to Resolve Proposal Compatibility Issues

> Guidance for troubleshooting and resolving proposal compatibility issues within fabric Dropship.

If a proposal is failing due to compatibility errors, it may be caused by several common issues. Use the guide below to identify and resolve the problem.

## Are you using the most up-to-date version of the merchant’s template?

**Cause:**\
Suppliers must use the merchant-defined import template, and merchants may update their templates at any time. Using an older file can cause compatibility failures.

**Resolution:**\
Always download a **new blank template** in Dropship before creating each proposal. This ensures you are working with the latest template version and merchant requirements.

## Do the items exist on another active proposal?

**Cause:**\
fabric Dropship does not allow items to be created on a new proposal if they already exist on another active proposal (for example, not completed, declined, or archived).

**Resolution:**

* If the new proposal includes updated attributes for items already in an active proposal:
  * **Archive the original proposal and the failing proposal**, then create a new proposal containing the desired items.
* If the new proposal does *not* include updates:
  * **Archive the failing proposal** and contact your merchant partner to confirm the anticipated approval of the original proposal.

## Are the items already permitted to the merchant?

**Cause:**\
If items were previously approved by the merchant, fabric Dropship does not allow a new product proposal for those same items.

**Resolution:**

* Review whether the approved items require enhancements or updates.
  * If updates are needed:
    * Archive the failing proposal and create a **cost update proposal** or **attribute update proposal**.
  * If no updates are required:
    * File a ticket with **fabric support** for assistance.

## Were the items previously requested for deletion?

**Cause:**\
Even if deleted, fabric Dropship maintains a record of the item. Attempting to resubmit it can cause compatibility failures.

**Resolution:**\
File a ticket with **fabric support** to reinstate previously deleted items.

## Are failures due to invalid or unexpected values?

**Cause:**\
Merchants define proposal rules and required values. If a field is populated with an unsupported value, the proposal will fail.

**Resolution:**

1. Review the merchant’s file and use one of the **expected values** shown in the dropdown or listed in the **Expected Values** tab.
2. If you do not see a dropdown or expected values tab, **download a new version of the merchant’s template**.
3. If expected values are still unclear or missing, file a ticket with **fabric support** for further assistance.
