• Message number: 182

• Message text: External transaction control is not permitted for order/schedule line

The order or item/schedule line can not be changed together with
external transaction control.

System Response

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?

This could be because the order or item/schedule line has a status that
does not permit changes at the same time as external transaction
control is being used. Another possible reason is that the
order/item/schedule line is being used in a scenario (for example,
transportation planning) and so external transaction control may not be
used in this case either.
For more information on the restrictions when using external
transaction control, see the documentation for the methods you are
using.
