Hi @jimpatel ,
Please try this code to create a calculated column in Table 1. When you use this code, please make sure the data type of [True/False] is text.
VAR _List =
VALUES ( 'Table 2'[True/False] ),
'Table 2'[Part number] = EARLIER ( 'Table 1'[Part number] )
IF ( "TRUE" IN _List, "TRUE", "FALSE" )
Result is as below.
