Please create an ECS environment for the foreign currency valuation run

What causes this issue?

For posting the foreign currency valuation, an
ECS environment has not been defined.
For error handling, postings of a foreign currency valuation use
suspense accounting and error correction (ECS). If an error
occurs while processing the foreign currency valuation, the error
messages
are displayed in the ECS transaction and the posting can
then be postprocessed manually.
For more information about the ECS environment and error correction, see
SAP Library.

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

How to fix this error?

Assign an ECS environment to the foreign currency valuation:
<DS:SIMG.FAGL_FCV_ECS>IMG</>
For the foreign currency valuation, ECS environment FAGL_FCV is shipped
as sample settings.
We recommend you copy these settings from the delivered customizing.
