How To Fix FARR_INB_MAIN080 - Item &1: Processing of predecessor chain leads to a negative quantity

SAP Error Message - Details

• Message type: E = Error

• Message class: FARR_INB_MAIN - Messages for Inbound Processing

• Message number: 080

• Message text: Item &1: Processing of predecessor chain leads to a negative quantity

What causes this issue?

Item &v1& is part of a predecessor document chain. It refers either to a
predecessor document or it represents a predecessor document itself.
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 attempted to process one or more items of the predecessor
document chain that has item &v2&<(>,<)> which represents the
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 &v1& for accounting principle &v3&.

How to fix this error?

Correct the sender component documents on which the predecessor document
chain is based, so that the overall quantity of the items in this chain
is still positive after the aggregation.

Procedure for System Administrators

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

  Cause:
  
  
  Negative Quantity Calculation: The error typically arises when the system attempts to process a transaction that results in a negative quantity for an asset or item. This can happen due to incorrect data entry, such as:
  
  Incorrectly entered acquisition or transfer values.
  Incorrectly defined predecessor relationships between assets.
  Manual adjustments that lead to inconsistencies in the asset history.
  
  
  
  Configuration Issues: There may be issues with the configuration of the asset accounting module, particularly in how predecessor chains are defined and processed.
  
  
  Data Integrity Issues: There may be inconsistencies in the underlying data, such as missing or incorrect entries in the asset master records or transaction history.
  
  
  Solution:
  
  
  Review Predecessor Chain: Check the predecessor chain for the specified item. Ensure that all predecessor and successor relationships are correctly defined and that they do not lead to negative quantities.
  
  
  Check Transaction Data: Review the transaction data related to the asset. Look for any entries that may have been incorrectly entered or adjusted, leading to a negative quantity.
  
  
  Adjust Values: If you find any incorrect values, adjust them accordingly. This may involve correcting acquisition values, transfer values, or any other relevant financial data.
  
  
  Consult Documentation: Refer to SAP documentation or help resources for guidance on how to properly configure and manage predecessor chains in asset accounting.
