Hi shyam,
If that is not the standard behaviour then why for our case system is behaving like this. we have assigned CI for GR/IR G/L in G/L master and also in derivation rule with business transaction.Even then why system is deriving the CI of the expenses for that GR/IR line item while doing the MIGO.So far the document spliting concept is not configured in our system.No new G/L.
