I found this error when im trying to export report to excel.
This message is for C/AL programmers:
The call to member LeftHeader failed. Microsoft Office Excel returned
the following message: Unable to set the LeftHeader property of the
PageSetup class
Do you have any default printer set?
Yes printer is set for the PC.
some time back I read a MS support case that this problem will arise when we dont have access to default Printer…
Problem sorted. Default printer was not recognized by the server. now its ok i gave the another working printer as a default printer
Thanks for sharing the solution
