ICBOM01.rpt giving connector error when processing CSV_FILE

SOLVED

ICBOM01.rpt gives connector error when processing CSV file made by ICCOMP.DLL

V2020
I get no error if I suppress the sub-report so I know it is that sub-report showing BOM details

Error happens on server with O365 and another server with no Office installed

All the SAP crdb*.DLL appear in C:\Program Files (x86)\SAP BusinessObjects\SAP BusinessObjects Enterprise XI 4.0\win32_x86

Seems to have started for no reason
