Reference flow type does not exist

Hi,

I am facing an issue in the Reference flow type in the below scenario.

Error Message :

Reference Flow Type 040 I043 does not exist

Message no. RECABC010

in the above scenario I am reducing the Condition unit price and the expected result is it should trigger relationship 020 (follow up posting due to condition reduction) but the system triggers relationship 040 (own use).

Please help.

Regards

Satish
