How To Fix RY090 - Error in the hierarchy; elementary transaction &1 is a Bermuda option

RY090 - Overview

• Message type: E = Error

• Message class: RY - Messages for RM Basis

• Message number: 090

• Message text: Error in the hierarchy; elementary transaction &1 is a Bermuda option

What causes this issue?

Elementary transaction &V1& is a Bermuda option. However, at least one
previous elementary transaction has a different transaction form.
The hierarchy for Bermuda options is restrictive. It must not contain an
elementary transaction with a transaction form other than that for
Bermuda options above the Bermuda option itself.
Your hierarchy must have the following structure:
Bermuda option
,,|_Bermuda option
,, |_Bermuda option
,,,,,, |_Underlying,,
It must not be structured like this:
Elementary transaction
,, |_Bermuda option
,,,, |_Bermuda option
,,,,,, |_Underlying
An exception is the complex transaction (transaction form 200). If the
first elementary transaction is a complex transaction, then the Bermuda
option(s) below this level can be depicted as subtransactions. The same
restrictions as for non-complex transactions apply to the
subtransactions themselves in terms of transaction 063 (Bermuda option).
<ZH>Note:</> The system determines the number of the elementary
transaction for a generic transaction (transaction RCA00) by assigning
numbers, starting with 1, on each level of the hierarchy tree, starting
from the top and working downwards. In the external data transfer, this
number matches the NGIDNR, the sequential number for a GID in the FGET.
Example
Number,, Tree
1,,,, Elementary transaction (top level)
2,, ,, |_ Elementary transaction (second level)
4,,,, |_Elementary transaction (third level)
5,,,, |_Elementary transaction (third level)
7,,,, |_Elementary transaction (fourth level)
3,,,, |_ Elementary transaction (second level)
6,,,, |_Elementary transaction (third level),,

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?

Either choose a different transaction form for the elementary
transaction, or correct your hierarchy for the generic transaction.
