Here are the steps that you will need to follow to catch record numbers 1,5,11,15,21,25,31,35.....so on.
Step1: Create an expression T/F and define a variable to count the number of records, say we name it as "CNT"
CNT (int) = CNT+1
Step2: In the same T/F, at the end of all the ports define a flag, say we name it as
flg_VALID_ROW (string(1))=
IIF((SUBSTR(TO_CHAR(CNT),-1)= '1' or
(SUBSTR(TO_CHAR(CNT),-1)= '5'),'Y','N')
Step3: Next define a Filter T/F, where you can catch hold of the record using flag = 'Y'
Filter Cond'n: flg_VALID_ROW = 'Y'
