How To Fix CNV_20100536 - Table T8G17 is excluded from phase CONVERSION, but build up afterwards

CNV_20100536 - Overview

• Message type: E = Error

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

• Message number: 536

• Message text: Table T8G17 is excluded from phase CONVERSION, but build up afterwards

What causes this issue?

The assignment of account intervals to an Item Category (table T8G17)
will be rebuild in phase "Postprocessing programs DURING system lock"
dependent on the mappings (accounts- and item category mapping as of
activity 'Specify Item Categories'.
Therefore table T8G17 must not be converted in phase CONVERSION, hence
is excluded from the conversion in phase CONVERSION.
In the postprocessing phase table T8G17 is newly buildup for the target
chart of accounts and new account intervals are build up from scratch
(activity 'Build Item Category Customizing').
If you have specified in the mapping phase to retain the original chart
of accounts unchanged (by setting the <ZH>Copy Rows</> indicator), then
also in T8G17 the entries of the original chart of accounts remain
unchanged.
