Message text: Priority set more than once at B level for G/L acct &1 &2 in CoCd &3
The system found that in the mapping table for
<DS:TX.CNV_20100_TX_BSEGMENT>B segment</> merges the priority indicator
was set more than once for G/L account &V1& &V2& (that will exist after
the merge) in company code &V3&.
Consequently, it is not clear which settings from which company code
will take priority in the merge.
The system issues an error message and will not allow you to continue with this transaction until the error is resolved.
Either set the priority indicator only <ZH>once</> for the given G/L
account in the mapping table for B segment merges, or check the settings
of the new account manually after the merge.
