When writing checks to vendors, the transaction appears in my register, but it's not always captured for the specific vendor. Why does this happen?

A vendor transaction report or listing only shows the bills that have been paid.  If you did not enter a bill and use pay bills to pay it, then the vendor has a credit = to the check amount.  Use pay bills, select the bill and apply the credit.  If no bill was entered then things are fine

I don't use Pay Bill. I write monthly checks to Vendors and use the "New Transaction - Checks". When searching for all payments to a specific vendor, sometimes every payment is captured under that Vendor, sometimes it's not. It is captured in the Check Register, however. I don't do anything different.

I just noticed this problem too in my personal bookkeeping QB file.  For years I have entered batch transactions (credit card, checks) or single entries, for many different companies, and the transaction always showed up under each Vendor.  But now every Vendor in the Vendor Center shows no transactions!  This has nothing to do with entering Bills and paying them.  If you pay JQ Public $20.00, then that transaction should show up in that Vendor's Information "Transaction tab".  If there are no Invoices against a Vendor, the balance will show 0.00 no matter how many checks have been paid to that Vendor, and that's ok.  I'm talking about no transactions showing at all for each Vendor!  What is wrong in this new company file (personal file).  How do we fix it.  Thank you.  Are you going to do a patch?  Thank you.

My apologies.  Date filter was not set correctly.  All good now.  Sorry.
