Not able to get sc_req_item table on trigger created

[mishrarakes]

1. On Submit, Assign ticket to Data Warehouse(create new group) group. 
2. Create Security checkbox on the SCTASK (only Visible on the SCTASK, not on the catalog form).
3. If fulfiller checked the security checkbox before closing the SCTASK then trigger an approval to the Security(create new group) group 
4. If security team approves the request then create new SCTASK and assign it to ServiceNow team else close the RITM.

I have created the frontend form for this the  problem I am facing is 

1) Not able to get  "sc_req_item" on the table inside trigger record created due to which I am not able to create SCTask on RITM , can some one help please, I have to do this with flows only, I tried with business rule and it worked.

The scope(Application) is already global .

@mishrarakes 

this is by design and expected behavior for flow designer

[sc_req_item] Table not available on Trigger of Process Automation Designer 

You will have to proceed with business rule only here.
