Issue: Promoting Headers removes all other rows
I have a table with a about 186 rows. The headers are on the first row.
When I promote headers, all rows but the first row of data disappears.
= Table.PromoteHeaders(<table>)
Not sure why?
A table definition in Excel should work just fine. Power BI will read that meta data and pull the entire table contents, based on the current size of the table.
NOTE: This statement is only valid for rows of course. Dynamic columns are not well supported.

what's your row delimiter? Got some sample data?
Show the data before promotion. And share your full m code (view/advanced editor + copy/paste)
Hey thanks. I think I figured out what was going on.
Not sure if there is a workaround but if you set a dynamic named range in excel and injest the data into power query, at first it show the entire dataset. But the moment you try and run a function or anything on the dataset, it somehow drops all the rows.
I made the dynamic named range with this formula in excel.=$CG$7:INDEX($CG$7:$CU$2102,COUNTA(CG8#)+1,COUNTA($CG$7:$CU$7)-1)
What it does is expand or contract the named range based on the row and column count.
My ultimate goal was to set up a process where I can "enrich" certain data from using the info from this named range. Since the size of the table changes, I figured it would be good to have a dynamic named range. The issue is that PowerQuery doesn't seem to play well with Dynamic Named ranges.
I can't use a table because I need the spill functionality to adjust the size of the range.
Not sure if there are any good workarounds.
