Out of memory Error while querying SQL Script based Calculation View

Question

Hi All,
I wanted to test the performance of Graphical and SQL Script based Calculation views.
Created Graphical (CA_GRPH) and SQL Script (CA_SQL) Calculation views.
Analytic View (AN_GRPH) for both Calculation views are the same which is Graphical based (90 Attributes and 5 Measures)
In Analytic View data foundation I have a Fact table which has 1.5 Billion records and 9 Dimension Tables –collectively 500 million records (7 Attribute Views). 9 Referential joins with cardinality N:1 and 1 Referential join with cardinality N:N.
I wanted to keep (CA_GRPH) and (CA_SQL) as a base Calculation views and leverage those to create various calculation views (Will be creating different Calc views for respective Business segments)
In order to test this I have created below calc views on top of base calc views.
Graphical Based: Created (CA_GRAPH_XYZ) by having CA_GRPH in projection with 30 Calculated Columns. – This retrieves data in 13 secs
SQL Script Based: Created (CA_GRPH_ABC) by having CA_SQL in projection view with 30 calculated columns – This errors out after 1.50 mins.
Could not execute 'SELECT "COLUMN_A","COLUMN _B"," COLUMN _C"," COLUMN _D", SUM("COLUMN _REVENUE") AS ...' in 1:50.480 minutes .
SAP DBTech JDBC: [2048]: column store error:  [2048] column store error: search table error: [1000002] Error executing physical plan: exception 1000002:

Any suggestion / help in fixing this issue will be greatly appreciated.

Hi Raj,
Thanks for your time, please find edited snap hot of Analytic View (AN_GRPH) below,
Calculation view(CA_SQL)
        /********* Begin Procedure Script ************/
BEGIN
       var_out =
     SELECT
            "COLUMN_1"
            "COLUMN_2",
            "COLUMN_84",
            "COLUMN_85;",
            SUM("REVN") AS "REVN",
            SUM("MGN") AS "MGN",
            SUM("ORD_QTY") AS "ORD_QTY",
            SUM("SYS_QTY1") AS "SYS_QTY1",
            SUM("SYS_QTY") AS "SYS_QTY"
FROM
      "_SYS_BIC"."XYZ/AN_GRPH"
GROUP BY
            "COLUMN_1"
            "COLUMN_2",
            "COLUMN_84",
            "COLUMN_85";
END
/********* End Procedure Script ************/
Later i have built one more Calculation view(CA_GRPH_ABC) using (CA_SQL)in projection. i have 30 calculated measures in this final calc view. this final calc view is throwing above mentioned error.
Not sure if i can use SQL script based calc view in graphical based calc views?
