I am posting this error after searching many related errors in sap scn and other places but none of them were close to my issue.
Issue which I am facing is there is an existing scheduling agreement in system and for that existing agreement few new line items are getting added through an IDOC type - BLAORD. As scheduling agreement is coming from some other system via an IDOC.
Now IDOC is getting failed with error - 'conversion factor could not be determined' message number ME897. Since this inbound IDOC is associated with SAP AIF so which line item has exact issue is not visible and there are close to 1000 line items in agreement.
Though, at initial check I see base unit of measurement and order unit of measurement conversion ratio is maintained for almost all material.
Could I have any suggestion on this if anyone has faced similar issue.
