Hi all,

in our source system we have an hierarchy like this for example:

1.level        YEB_FI                                                       

2.level               YEB_FI_AP

3.level                   YEB_FI_AP_ACCOUNT_DIR

4.level                                  P02~300@YEB_FI_AP_ACCOUNT_DIR

i promoted first user hierarchy with dependencies, then i promoted user groups but

in target system 1.level, 2level and 3. level is ok they have relation

but 4. level is not related with hierarchy

and i cant solve this. icant carry again:
