Hi All,
When a service confirmation order is created , the serial number entered is validated against the serial number maintained in R3 against the material .
In my case , even though i have done the required customization and serial number is maintained in R/3 , i get the error message 'invalid serial number' even though i enter the correct serial number . Upon debugging i found that the BAPI 'CRS_SERIALNR_CHECK' carries the required validation and it is called correctly from CRM side. I have also set the serial number profile to 04 (Check against SAP ECC).
Thanks,
