Depends on one field, other field (lookup select box ) refering a grp , should show the options

[VinushaN0004809]

for a catalog item, Sap system is reference field and approval by is lookup selectbox (referring a grp)
if sap system is A,B,C, then approval by should be particularly 3 grp members need to show as option in approval by field and D,E,F as Sap system then other 3 persons need to show in approval by field ...like this there are 10 set ...how can i implement this

there is a field called "SAP SYSTEM" ( referring to "cmdb_sap_system" table ) 

other field called "approval by"( it is selectbox and, in autopopulate - it will fetch the "cmdb_sap_system"  table and populate the "approval group" 

The "approval by "  field is auto-populating the approval group but it need to show group members
