Plant Maintenance Data Load issue

Dear Experts,

I am assigned to project to support Plant Maintenance Module, the client have the PM Standard Objects active in Production, but it seems who ever activated it didn’t load any data. Now the user is requesting to load this data and initiate the Delta.

My issue is when I attempt to full load or Initial Load any of the PM data loads it gives me 0 records, Data Sources like (2LIS_17_I0NOTIF, 2LIS_17_I3HDR, 0PM_OM_OPA_1, 0PM_OM_OPA_2, 2LIS_17_I3OPER, 0PM_OM_OPA_1, 0PM_OM_OPA_2, 2LIS_17_I3HDR, 2LIS_17_I3OPER, 0PM_MEASUREMENT)

Can you please help?

Regards,

Mohammed
