Fetching order data from liveCache

Hi,

I am trying FM PAPO/OM_PEG_CAT_GET_ORDERS to get order data from liveCache

I am giving the following inputs

1. PEGID which I am getting from /SAPAPO/DM_MATERIAL_GET_PEGID for a given product location.

2. ATP category in IT_CATEGORY = BM and CC

3. V_SIMSESSION = 000

4. IV_IONODE_PEG_SEL = 0

But I am getting LC_COM_ERROR and no output.

What parameters am I missing ?

Regards,

Yogesh
