Hierachy Load error from R/3

Hi All,

I got an error while loading hierarchy from R/3 to BW. error is

<i><b>Diagnosis</i>

The hierarchy level of the parent node must be one larger than the

hierarchy level of the actual node. This is not the case for the node

with ID 00092826 and its parent node with ID 00092827 .

<i>System response</i>

<i>Procedure</i>

Correct the hierarchy level of the node or of the parent node in your

source system.

<i><b>Procedure for System Administration</b></i>

Can anybody help how to solve this error and where to correct this hierarchy in R/3.

This is an urgent issue.all my dependant loads are stopped due to this error.

Thanks in advance

Narendra.
