How To Fix UCFP001 - &1 &2 occurs more than once

SAP Error Message - Details

• Message type: E = Error

• Message class: UCFP - Messages for Period Initialization

• Message number: 001

• Message text: &1 &2 occurs more than once

What causes this issue?

You assign a source document type that posts with deferred taxes a
unique target document type that the system uses to adjust deferred
taxes for that source document type.
The document type assignment must be one-to-one. This is not the case in
the current settings because document type &V2& occurs more than once.

System Response

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?

Define a one-to-one document type assignment: Assign a unique target
document type to each source document type in such a way that each
target document type points to one source document type only.
