Autofill requires data in the cell immediately to the left for it to work. Otherwise, it doesn't know how far down the page to fill. It will work correctly if you have contiguous blocks of data i.e. no blank rows &/or no blank columns in your data table.
You can also use Fill from the Home Tab --> Editing block and "Fill" option.
In this case you have two options...
1. Delete the column "CM" to get back to a contiguous block or...
2. Move the "thing" you have in "CN2" over to "CM2" use Fill, the way you always used to, then - with the range still highlighted - drag that range back over to column "CN"
Thanks for your reply, this is a report run out of the Dynamics AX system, that takes up all the hidden columns. the CM info is blank on AX when I copy over, this is run as a report and because when it is usually hidden, it seemed to take the next unhidden column as a autofill reference, but it no longer does.
that's my issue, is it a change in the software? or can I fix it through the settings/code
Hi Sam Not sure I can answer this as I don't use Dynamics but, sounds as though it might be Dynamics settings - if it's just been updated and was working for you before. Also, reports that are created from other systems (such as Dynamic AX, Dynamics 365, SQL, Vector etc.) may be set up to add or remove columns. My previous response should solve the problem but will need to be carried out every time you get a new report. If it can be fixed at source (Dynamics) that's the thing you should do. If not, you will need to think of using Power Query in Excel and creating a template - but that takes a little more effort. :-(
