change the automatic mapping for dimension /measure ( Planning Model)

Hello Everyone,

I added a new source file ( excel file) to existing Planning model and when i open the imported file it shows on the left hand the new excel file with its objects ( dimensions and measures) and right hand side panel shows the existing model dimensions and measuers.

Problem here is that the objects are mapped wrongly and I see no option to change the mapping i.e Dimension from excel is mapped to wrong dimension of existing model and also the measure ( from excel ) is displayed as dimension and there is no option to change it .

Have anyone faced similar problems, it would be great if you can advice. Thank you in advance!

Best Regards,

Anita
