HANA DB - Table - Not able to delete records!!!

Dear All,

I have created a table at HANA DB and imported records into that. Following is the SQL used to create the table:

CREATE COLUMN TABLE "HCM"."HCM" ("COL1" NVARCHAR(21) NOT NULL ,

      "COL2" NVARCHAR(30) NOT NULL ,

      "COL3" NVARCHAR(30) NOT NULL ,

      "COL4" NVARCHAR(30) NOT NULL ,

      "COL5" NVARCHAR(30) NOT NULL ,

      "COL6" NVARCHAR(30) NOT NULL ,

      "COL7" NVARCHAR(30) NOT NULL ,

      "COL8" NVARCHAR(30) NOT NULL ,

      "COL9" NVARCHAR(30) NOT NULL ,

      "COL10" NVARCHAR(30) NOT NULL ,

      "SIGNDATA" DECIMAL(20,

      2) CS_FIXED,

      PRIMARY KEY ("COL1",

      "COL2",

      "COL3",

      "COL4",

      "COL5",

      "COL6",

      "COL7",

      "COL8",

      "COL9",

      "COL10")) UNLOAD PRIORITY 5 AUTO MERGE

However, I am not able to delete records from the table. How can I delete records from a table(OLTP) in HANA DB?

I thought it should be straight forward as we do for other RDBSM - Oracle or SQLServer, using DELETE FROM ***..

Thanks in advance for the help!
