Error while exceuting a SAP HANA Procedure

Question

Hi HANA Gurus,
I am new to HANA SQL Scripting and I have created the following procedure
CREATE PROCEDURE "RAJ_HANA"."CURSOR_FOR_LOOP" LANGUAGE SQLSCRIPT
AS
VAR_EMNO INTEGER;   
CURSOR EMP FOR SELECT EMPNO FROM "RAJ_HANA"."EMP";
BEGIN  
FOR EMP_CUR AS EMP DO
FETCH EMP INTO VAR_EMNO;
INSERT INTO "RAJ_HANA"."EMP_1" VALUES(:VAR_EMNO) ;
SELECT * FROM "RAJ_HANA"."EMP_1";
END FOR;
END;
Error:
Could not execute 'Call "RAJ_HANA"."CURSOR_FOR_LOOP"' in 41 ms 684 µs .
SAP DBTech JDBC: [150]: statement cancelled or snapshot timestamp already invalidated: [150] "RAJ_HANA"."CURSOR_FOR_LOOP": line 8 col 1 (at pos 147): [150] (range 3): statement cancelled or snapshot timestamp already invalidated
Please help

If you want to copy data between two tables why use a cursor at all. This seems rather inefficient.  You can bulk insert data by embedding the select into the insert.  Here is an example:
insert into "SP8DEMO"."playground.sp8.data::PurchaseOrder.Header"
  select * from "SP7DEMO"."playground.sp7.data::PurchaseOrder.Header";
In your case I believe you could accomplish the same with
INSERT INTO "RAJ_HANA"."EMP_1" (EPMNO) SELECT EMPNO FROM "RAJ_HANA"."EMP";
