I have populated data in Item Branch Category 1 in t_src_sales_tmpl table. After 'EBS Full Dowload' data is populated into t_ep_e1_it_br_cat1 (Item Branch Category definition table) and is also updated in mdp_matrix. Now I want to add this level 'Item Branch Category 1' into worksheet. However I cannot view the level in worksheet editor [Worksheet Designer --> Aggregation. In the Available Levels box]. Is there anything that I need to do to make a level visible in 'Available Levels' of the Worksheet?
