Please check that the column you are mapping to has a space in the column name or a special character.
The column's internal name is used for performing the column mapping
therefore the column mapping list needs to have the column's internal name
specified.
If the column has a space in the name SharePoint uses the
characters "_x0020_" to represent a space so you need to specify this in the
column mapping list when entering the 'To Column' names as below:
The table below represents examples of characters that could be in a column's internal name and how to represent them in the column mapping list:
space |
_x0020_ |
& |
_x0026_ |
' |
_x0027_ |
- |
_x002d_ |
{ |
_x007b_ |
} |
_x007d_ |
