SAP Error Message - Details

• Message type: E = Error

• Message class: CNV20200 - Messages for development class CNV_20200

• Message number: 390

• Message text: Ref. company code &1 merged into target CoCd &2 => special priority

What causes this issue?

Reference company code &V1& is merged into the existing company code
&V2&.
By default, the settings from the reference company code would take
priority when table keys become identical because of the conversion.
In this case, however, the target company code exists already, and as a
rule special settings and data from this company code should be
transferred to the target.
These are the following:
VAT registration number (T001-STCEG)
Additional information regarding the company code (table T001Z)
Address data for the company code (ADR* tables)
Name of the related company (table T880)

System Response

How to fix this error?

assigned.
The priority routine CNV_20200_PRIO_AD_OBJKEY evaluates the priority
field for TABNAME=T001 in accordance with the logic of routine
CNV_20200_PRIO_BUKRS_TARGET.
