Hi,

I'm utilizing the FM BAPI_INSPOPER_RECORDRESULTS to prevention inspection characteristics (on SINGLE_RESULTS level) and it's moving conscionable fine.
The occupation ist that we person a calculated diagnostic depending connected the different entered characteristics.
The calculation is moving good erstwhile I participate the values utilizing QE51N transaction (values calculated, and diagnostic closed), but it's not moving utilizing the FM BAPI_INSPOPER_RECORDRESULTS. The calculated diagnostic is not calculated and not closed.
I've tried the solution described successful the SAP Note 3088890 by calling the BAPI doubly with a perpetrate betwixt the 2 calls but it's inactive not working.
Do you person immoderate thought however to trigger the re-calculation ?

Thank you
