Same Period Last Year Not Working With Filter

I think best thing is to do is create 2 filters

- One with your actual measures with Filter

SalaryWithCC(WithoutWPS)  = CALCULATE(SUM(ZFAGLFLEXA_FI_DOC[NEWHSL]) ,FILTER(ZFAGLFLEXA_FI_DOC,ZFAGLFLEXA_FI_DOC[RCNTR] <> "" ),FILTER(GLMapping,GLMapping[GLGroup_Index]="3"),FILTER(ZCEPCT_PRFT_TXT,ZCEPCT_PRFT_TXT[INCGRP1]="INCGRP1") )

- After that you should create Last Year Measure

SalaryWithCC(WithoutWPS) Last Year = CALCULATE( SalaryWithCC(WithoutWPS), SAMEPERIODLASTYEAR (Calendar[Date]))

Make sure that your calendar is marked as "Date Table"
