The program searches for debit vendor items and evaluates documents with such items.

If the document includes a counter-item, whose account can not be found in the Customizing activity Specify Accounts for Deferred Tax, then the item processing is complete – the payment has not been identified.

If the document includes a counter-item whose account can be found in Specify Accounts for Deferred Tax, and which is marked as a payment account, processing continues – the payment has been identified.

If the document includes a counter-item whose account can be found in Specify Accounts for Deferred Tax, and which is not marked as a payment account, processing continues – a payment is searched for through an interim account.

Within interim accounts the program continues to search for the payments with special algorithm following the tree structure as shown in the following graphic:

The following rules apply:

• All the items cleared together on interim accounts are tracked.
• Tracking continues through credit items of cleared documents all the way to a document the counterpart of which is included in the Customizing activity Specify Accounts for Deferred Tax, and marked as a payment account.
• If several payments are found (that is, several entirely different business transactions have been cleared on an interim account), these are classified on the basis of compatibility with symbol variable. If it is not possible use the symbol variable (for example, the field is empty), individual payments are processed, starting with the last one and going back.
