COUNT(

    WHEN PROCESS EQUALS (

      "_STD_CEL_AP_ACTIVITIES_TABLE"."ACTIVITY_EN"

      EQUALS (("_STD_CEL_AP_ACTIVITIES_TABLE"."ACTIVITY_EN")* to ANY to 'Remove Payment Block' END )

    )

    THEN

      "BSEG"."MANDT" || "BSEG"."BUKRS" || "BSEG"."GJAHR" || "BSEG"."BELNR" || "BSEG"."BUZEI"

I haven’t used PROCESS EQUALS before, and I’m finding it difficult to understand its syntax even after going through the documentation. I want to use it in view, so if you have any insights or examples on how to use it, please let me know.
