CNV_20100251 - Overview

• Message type: E = Error

• Message class: CNV_20100 - Messageclass for chart of account conversion

• Message number: 251

• Message text: Implicit merge of G/L acct &1 with secondary CostEl &2 due to CoA change

What causes this issue?

The system found that the G/L account &V1& is converted into
&V3& (according to the mapping). However there is already a
secondary cost element called &V2&, which is also going to be
converted into &V3& in connection with the chart of accounts
change.

System Response

In effect, this means that a G/L account (&V1&) and a secondary cost
element (&V2&) are going to be merged (implicit merge). This is not
allowed.
The conversion cannot take place.

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?

The mapping table must be adjusted accordingly.
