Specifying One-Time Distribution Rules 
The following is a list of transactions and documents in SAP Business One where you can assign distribution rules to G/L accounts that are involved in a specific transaction/document or a series of transactions/documents. This might be required in the following cases:
You have assigned a default distribution rule to the G/L account, but in a specific transaction/document or series of transactions/documents, you need to assign a different distribution rule.
You have not assigned a default distribution rule to the G/L account, but in a specific transaction/document or a series of transactions/documents, you need to assign to it a distribution rule.
Features
In all places listed below, the distribution rules can be changed at any time (before and after the transaction/document is added), unless otherwise stated.
Note
If you specify distribution rules at both the row level and the document level, SAP Business One takes the distribution rule information from the row level.
