Permit classification for WBS element (for PM order)

Hi!

I've set up an automatic permit based on classification and it is working already correctly (for the field CSEVPERMIT-ILART).

I would like to set up an another automatic permit, but for the WBS element (CSEVPERMIT-PSPEL). However this field is a numberic(8) field, so it allows only numbers (like 12345678), which is the ID of the WBS element in the database (which is the PRPS-PSPNR).

But I have to set up the automatical permit based on the "useful" ID of the WBS element (PRPS-POSID).

I have to set it up with the following mask: L++++++T* (if the WBS element matches the mask, then the permit have to appear in the order's permit list).

Is there a way to achive this?

Thank you
