What and Where can i find Location Name to be passed when using Bom_Bo_Pub.process_bom for creating

Hi, I wanted to try and use the api to create the Bill of Material . The problem which i am facing is , i am not sure from where and which table and what value should i be passing for location name when using the above said api.

I am passing a value that appears from the front end to the api and when i do that i get the following error message.

----------------------------------------------------------------

:1:BOM_INVENTORY_COMPS_INTERFACE

1:You must specify an existing location in the column LOCATION_NAME. (LOCATION_NAME=....C1153) (REVISED_COMPONENT_NAME=TEST_ASSEMBLY_COMP1A)

----------------------------------------------------------------------------------------

The locations (Stock Locators ) are existing in the system and got to know that mtl_item_locations is the table which holds the data.
