Absence request does not show in MSS approval lane

Hello

We are implementing the ESS/MSS Absence Request using HR Renewal (lastest version).

The ESS portion is working fine (the employee can make a leave request).

The backend customizing is also working fine (using transcation PTARQ we can send the mail, validate the requests an so on). Since the requirement are simples, we're not using the workflow, but the simple state/event mode.

However, we can not get the absence requests to show in the MSS Approval lane. It seems that by default, the Approval lane does not check those request (not workflow), and that i should use the POWL.

thus my question : could someone explain to me how to make this ?

or how to put the HRMSS_LR_APPR_G in a CHIP (will it check our request ?) ?

thanks

Guillaume
