CNV_20100261 - Overview

• Message type: E = Error

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

• Message number: 261

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

What causes this issue?

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

System Response

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

How to fix this error?

The mapping table must be adjusted accordingly.
