Problem Processing R Script in HANA Stored Procedure

Hello Community,

I have a stored procedure with very simple R code and output to a table with two columns.  The stored procedure is created successfully, and the R commands run fine in R separate from HANA, but there seems to be some problem with how the script is being processed.  Various errors are returned like END not found, "variable name" not found (see log excerpts below) depending on changes made to the very simple R script.

Can you help me shed some light on why this is happening?

System Details

• SAP HANA running on AWS instance
• RServe running on separate AWS instance
• R version 2.15.3
• Rserve version 0.6-8.1

Stored Procedure Code

CREATE PROCEDURE "SCHEMANAME"."STORED_PROCEDURE_TEST" (OUT results "SCHEMANAME"."RTEST")

LANGUAGE RLANG AS

/********* Begin Procedure Script ************/

BEGIN

v <- c(2,3,5,7,2,3)

w <- c(2,3,5,7,2,3)

results <- as.data.frame(cbind(w, v))

END;

/********* End Procedure Script ************/

Stored Procedure Call

CALL "SCHEMANAME"."STORED_PROCEDURE_TEST" ("SCHEMANAME"."RTEST") WITH OVERVIEW;
