Hi
When I am performing STC ( Single Transaction check ) for financial transaction I am getting following error message. 
Error Message 1- Internal Basic Key figure is empty
Message no K-308
Error Message 2 -
Message no K-249
End of the day processing job message log shows assignment of valuation rule not found for product type 51 A- (transaction - KLNACHT)
Can anyone advise what could be the root cause for this issue.
