Hi,
The message C171 comes from material Ledger. If C171 arises, then it
is completely correct, otherwise it would lead to an inconsistency in ML
currency. In this case something is not correct with the currency types
in ML. It assumes that the currency types are in ML different than at
the beginning. Examine the currency types to this order item with
transaction OB22 and/or CKM9 and table CKMLV and correct them, so that
MR11 can book.
They can look at themselves order history with CKMLOH and examine
therein the vouchers in all currencies. and correct them, so that MR11
can book. They can look at themselves order history with CKMLOH and
examine therein the vouchers in all currencies.
Always activate the material ledger for a complete company code
and copy all currencies from FI. This is the only way to ensure
the reconciliation with FI.
In addition, it is recommended that you activate the material
ledger for a complete company code because the invoice
verification can neither store invoices that contain materials
from plants the material ledgers of which are active nor more
materials from plants the material ledger of which is not active.
Please take a look in the note 425487, it describes the issue extensive.
