• Message number: 062

• Message text: Im target CoAr &1, no.rg. &2 overlaps in area &3 ( from CoAr &4 )

What causes this issue?

Documents from CoAr &V4& are converted so that they are stored in
target CoAr &V1& in number ranges &V2& in area &V3&.
This area overlaps with another area, in which other documents are
stored. For details on this second area, see the next message in the
log.

System Response

When simulating the document conversion, the system has found that
certain document intervals overlap. As intervals must not overlap, the
control tables for document conversion have to be adapted accordingly.

How to fix this error?

Using the next message, check in which area the numbers overlap and
adapt document conversion (using the maintenance view for tables
CNV_NRIV_O and CNV_NRIV_N) so that all overlaps are removed.
