• Message number: 678

• Message text: Processing of predoc chain &1 (&2) leads to a negative overall quantity

What causes this issue?

Item &v3& is part of a predecessor document chain, that is, it refers
either to a predecessor document or is a predecessor document itself or
both.
Items of a predecessor document chain are aggregated during processing.
The aggregation must not lead to a negative value for the overall
quantity after the aggregation.
The system tried to process one or more items of the predecessor
document chain that has item &v1& as its highest level predecessor
document. Processing of all items of this chain would lead to a negative
overall quantity after aggregation. Therefore all items that belong to
this chain could not be processed.

System Response

The system cannot process item &v3& for accounting principle &v2&.

How to fix this error?

Change the revenue accounting items of the predecessor document chain,
so that the overall quantity of the items in this chain is still
positive after aggregation.

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.
