Thanks for the quick reply, QueenC.

Unfortunately, none of what you mentioned solved my problem.  Your comment about "has already been listed" is a consideration.  How can I de-list these two?

We have over 110 employees, and the IIF file is over 1,300 lines.  Not near the 10K limit.

Both employees are active and not duplicated. I did read the 2020 post about an inactive employee and knew that wasn't the issue here.  I tried making them inactive, then active again, it did not change the outcome.

I've tried the IIF dozens of times, it is always the same two employees.

Doing their payroll manually does not create or indicate any problems.

I am now using a small test IIF file with just these two employees and loading into a copy of our QB.

I changed the name of one of the employees in QB and in the IIF file.  No joy.

Every line for these two fail to load, which indicates to me a problem with their employee record, but I cannot find anything there that is missing or out of the ordinary.

The employees are active employees and not found in any of the List menu dropdowns (i.e. Other Names List, Item List, etc).

Nothing about these two are unique.  I noticed both of them have a space in their Last Name (for Jr, III, etc) or a last name like "St John" but we have many others that share that characteristic.  Getting desperate to find the cause and fix it.

Hope you can help.
