Try this:
1) Open the BOM template in excel.
2) Insert new columns (How many ?)
Note: Be sure your columns are on the inside left of $END column.
3) Highlight the 4 default columns RMB on the columns and chose "Hide"
4) Click in the cell that you plan to add your own custom columns.
5) If you look at the upper left corner (lower of the toolbars) there is a box that tells you the cell name
Ex: You pick cell "E1" this box says "E1"
6) After you pick the cell you want click and have found the above mentioned box. Then type a name in this box for a new name for this cell.
Note: The name can
***NOT*** have spaces in it. Although this is legal "No_Name".
7) You don't have to add text in these cells, just make sure the names are right.
8) Save the worksheet under a new name and that's it.
You have now added a new name to these cells, and if you have these same names in your part or assembly it will show up in the BOM.
If you or anyone that reads this, need an example let me know,
I hope this helps, Scott Baugh, CSWP
