SAP Note 11604 - Value transfer from other area cannot be deselected.

Symptom

Program : SAPMA07C
For a depreciation area, which is not the balance sheet depreciation
area, a value transfer area (by default: balance sheet depreciation
area) is always set. This specification can only be overwritten but
never be cancelled, that is, it cannot be initially set.

Cause and prerequisites

Depreciation areas with an initial value transfer area can only be
posted by special transaction types. The 'ordinary' transaction
types, without restriction of the areas do not allow an account
assignment in such areas.

Solution
If you nevertheless want to manage such a area, you can only achieve
this by changing the control table under bypassing the Customizing.
The following example program may be helpful for this:
REPORT ZZWRTAFB.
TABLES: T093A.
PARAMETERS: BPLAN LIKE T093A-AFAPL. <<< chart of depreciation
PARAMETERS: BEREICH LIKE T093A-AFABE. <<< depreciation area
SELECT SINGLE * FROM T093A
WHERE AFAPL = BPLAN
AND AFABE = BEREICH.
IF SY-SUBRC NE 0. WRITE: 'WRONG INPUT'. STOP. ENDIF.
CLEAR: T093A-WRTAFB, T093A-XWRTID.
MODIFY T093A.
