Note: The following description of the Inquiry process applies if SAF (Store and Forward) is disabled or POS SAF is enabled. If On-Device SAF is enabled, a modified process applies. See :magic-link[POS Inquiry with On-Device SAF Enabled]{id="pos-inquiry-with-saf-enabled"} for more information.

In normal cases, Simplify will respond to a POS request in a timely manner.  If this does not occur (timeout), the POS will need to send an Inquiry message to Simplify requesting information from Fusebox about the transaction. An **Inquiry** message should contain all elements of the original transaction. 

-   Inquiry processing is required for the following situations:
    -   No response to a financial request.
    -   Field 1010 in the financial response contains one of the following:
        -   \*SLR STAND-IN.
        -   \*SLR COMMUNICATIONS ERROR.
- After sending an **Inquiry** message, Elavon highly recommends that the POS wait for a response and continue processing based on the response. *The **Inquiry** message should be resent until it receives one of the following*:
    - Fusebox approval for the original transaction
    - Fusebox decline for the original transaction
    - Fusebox no record response (Field 1010 = NO RECORDS FOUND).

:::::notice{important}

If the POS stops sending **Inquiry** messages for a transaction before receiving a Fusebox response, *the transaction will need to be reconciled manually*.
:::::


- The possible outcomes at the POS after sending an **Inquiry** message are as follows:
    - The POS receives a normal transaction response. (Transaction Type = original).  This response indicates that the **Inquiry** message and the original transaction were both processed online by Fusebox.  The POS should treat this response as a normal response to the original transaction.
    - The POS receives a no record response. (Transaction Type =22 and Field 1010 contains NO RECORDS FOUND).  This response indicates that the original request was NOT processed by Fusebox.  The POS can proceed in accordance with corporate policy.  E.g. a **Void Request** can be sent for the transaction.
    - If the **Inquiry** message times out at the host, the POS will receive a host down response (Transaction Type = 22 and Field 1010 contains "\*SLR COMMUNICATIONS ERROR." or "\*SLR SWITCH TIMEOUT.")  The POS must then re-send the **Inquiry** message until it receives a host response
    - If the POS times out before receiving an **Inquiry Response**, it must re-send the **Inquiry** message until it receives a host response.
- The **Inquiry** message can be re-sent by Simplify or through a back channel.  All rules for Inquiry processing apply regardless of how the **Inquiry** message is re-sent.
- The **Inquiry** message can be sent any time before the Gateway Batch Close.

The following table shows a sample of fields in the **Inquiry** message that may need to match fields in the original transaction.

|0002|	Transaction Amount|
