How To Fix PPECHK325 - Alternative line &1 is assigned at start &2

PPECHK325 - Overview

• Message type: E = Error

• Message class: PPECHK - iPPE Consistency Check

• Message number: 325

• Message text: Alternative line &1 is assigned at start &2

What causes this issue?

You have modeled the production line with iPPE. In the master data, an
alternative line exists that in turn contains parallel line segments
(stations). The parallel stations do not have a reporting point at the
start, however, a reporting point exists at the start of the production
line.

System Response

This constellation can also lead to problems during confirmation. A
reporting point is inherited along the stations from the back to the
front. It can therefore be inherited at multiple parallel stations. The
reporting point relationships in this case are no longer linear. As a
result, the sequential posting cannot be executed during confirmation.

How to fix this error?

Remove the assignment of the reporting point at the start of the
alternative line.
