SAP Error Message - Details

• Message type: E = Error

• Message class: ATP_BOP_VDM -

• Message number: 044

• Message text: Exception and fallback behavior are not consistent.

What causes this issue?

You are trying to set up a BOP variant and have chosen the exception
behavior <ZK>Stop Completely</> and the fallback restriction <ZK>Trigger
Fallback for Failed Material-Plant Combinations</>: this combination is
not allowed.

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?

Choose a valid combination of exception behavior and fallback
restriction. The following combinations are allowed:
Choosing exception behavior <ZK>Stop Failed Material-Plant Combinations
</> and fallback restriction <ZK>Trigger Fallback for Failed
Material-Plant Combinations</> will lead to the BOP run being fully
executed for all material-plant combinations without exceptions. If
there are requirements which cannot be confirmed as defined by the
confirmation strategies <ZK>Win</> or <ZK>Gain</>, their respective
material-plant combinations are removed from the BOP run and an assigned
fallback variant is triggered with a global restriction/filter on these
material-plant combinations.
Choosing exception behavior <ZK>Stop Completely</> and fallback
restriction <ZK>Trigger Fallback Without Restrictions</> will lead to
the BOP run stopping completely whenever there are requirements which
cannot be confirmed as defined by the confirmation strategies Win or
Gain. The fallback variant will be executed for all material-plant
combinations which are selected by the filter criteria defined in the
fallback variant without further restriction.
Choosing exception behavior <ZK>Stop Failed Material-Plant Combinations
</> and <ZK>Trigger Fallback Without Restrictions</> will lead to the
BOP run being executed for material-plant without exceptions. If there
are requirements which cannot be confirmed as defined by the
confirmation strategies <ZK>Win</> or <ZK>Gain</>, their respective
material-plant combinations are removed from the BOP run. The fallback
variant will be executed for all material-plant combinations which are
selected by the filter criteria used in the fallback variant without
further restrictions. Note that this combination of exception behavior
and fallback restriction may lead to the same requirements being checked
again in the fallback variant, although it has already been checked
successfully before. The corresponding business documents will then be
updated with the last result in a sequence of fallback variants.
