Excel Add In : [Table] does not have a reference data source

Hello all,

I am trying to import a new COA through excel add-in. We always used this way for previous COA. But we get an error now as soon as I click on OK to open the table in Excel (Add table > Main Account > OK > ERROR!)

Can someone help ? I have found only one proposition : to reference MainAccount table in MaintAccountTemplate table, but it doesn't work ...

We are on Dynamics AX2012 R3 CU8.

Many thanks

Nicolas
