IN operator in Crystal Report
({i_NonPfcIncDetStt.TeamCode} IN ['ABC','DEF']) perhaps?
Yep, use the brackets not parens.
For fancy, you can put the to-match strings in a delimited string variable, and then use SPLIT.
@toMatchList
"ABC,DEF,MDV,HLV,ILY,TLA,OMG,LOL,GOD,ETC"
({i_NonPfcIncDetStt.TeamCode} in Split(@toMatchList, ","))
For extra-fancy, you can do pattern matching.
