GLSU Error Message 1002 during parking documents

Hi,

My users had met an error message as beblow in excel GLSU add-in.

Error during GLSUpost

Error 1002 during GLSUpost

Invalid column number 1.

After the error happened, the expected document number was not returned in excel file. But when check in FBV2, the documents were already parked.

This would cause the duplicated documents in system.

Did you run into such problem before? Please throw some light to me.

Thanks!

Emma.
