MESSAGE:Transactions to accounts payable must include a vendor.

Create a vender "PettyCash"???

I appreciate you for bringing this to our attention, @Hawkins Bag.

When posting to Accounts Payable it will automatically prompt you to enter the vendor’s name.

In the meantime, we can use the Verify and Rebuild data utilities. Having said that, we can verify and correct the most typical data errors in your company file. Please make sure your QuickBooks Desktop for Mac is up to date as well.

Here’s how:

1. From the File menu, click Utilities.
2. Select Rebuild Data, then select OK to close all windows.
3. Follow the on-screen instructions to back up your data.
4. When the tool finishes, select OK.
5. Select Show in Finder to locate backup, then click OK.
6. Once the rebuild’s finished, click OK.
7. Click Verify Data, then select Rebuild Now once QuickBooks finds an issue with your company file.

Let me know in the comments if you need further assistance with your transaction. I’m just one post away from assisting you. Have a great day!

I have done that, but thanks for the suggestion. 

I have tried this and even reached out by phone. Nothing seems to fix my problem.I cannot split out the expenses, as I have done in the past. I can save the check only if I have it expensed to one item.
