Limit PO price is shown as Zero in SUS

HI,

We are creating a Limit PO in ECC with some limit value. we are getting following problems,

1. In SUS portal, the PO price is Zero.

2. The UOM picked is piece(ST), whereas the PO unit is AU (activity Unit).

Where am I wrong? How to populate the price in SUS portal PO.

Is there any mapping for UOM of ECC & SUS? Any table mapping where we need to update/change the UOM mapping.

Request your help.

Thanks & Regards
