SAP Error Message - Details

• Message type: E = Error

• Message class: FKKBIX - Conv.Inv.: Billing (Invoice Preprocessing)

• Message number: 055

• Message text: Dependency is not assigned for billable item (reference &1)

What causes this issue?

Billable items with the record types "Payments", "Taxes" and "Texts" are
attachments to billable main items. To ensure that grouping across
record types is correct, the fields PY_GROUP, TAX_GROUP and TXT_GROUP
must be filled correctly. If a dependent billable item does not have a
value in the grouping field, it is not possible for this item to be
assigned. The system therefore terminates processing of the entire
source transaction.

System Response

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