Requisition Account Generator is not calling the custom process

Hi All,

I have customized the Requisition Account Generator.
I created a new Default Account Generator process and loaded the process into the database by using the WFLOAD command and then i went to the GL--> flexfield--> Key--> Account
and queried the PO Requisition Account Generator and mapped the new process that was created.

When i create a requisition , i see that the standard requisition account generator is being called and created a charge account even when the custom process is mapped .

Please let me know how to get the custom process to be called instead of standard.

We are using R12 instance
