SAP HANA QUERY

Hi Experts,

I have the below SQL query and i have tried to convert it into HANA SQL Script, but i have a challenge with one line of Code. The line of code where a temporary table will be dropped and the select query starts again;

SQL QUERY;

     DROP TABLE [dbo].[wtx29]

    SELECT ROW_NUMBER ()over (PARTITION by vpm2.InvoiceId,OVPM.DocNum order by OVPM.CardName) as T ,

    VPM2.U_DocNum ,VPM6.TaxbleAmnt ,VPM6.WTSum,OVPM.CardCode,OVPM.CardName,OVPM.DocNum,ovpm.DocDate,

    vpm6.TxblAmntFC,vpm6.WTSumFC,opch.NumAtCard,OVPM.Comments,ovpm.DocTotal,ovpm.DocTotalFC,vpm2.InvoiceId

    into wtx29

    FROM OVPM INNER JOIN VPM2 ON VPM2.DocNum =OVPM.DocEntry

    inner join VPM6 on VPM6.DocNum = OVPM.DocEntry 

    inner Join OCRD ON OCRD.CardCode =OVPM.CardCode

    INNER JOIN OPCH ON OPCH.CardCode = OCRD.CardCode

WHERE  ovpm.Canceled <>'y'

DELETE FROM wtx29

WHERE T>1

SELECT * FROM wtx29

HANA SQL QUERY

CREATE COLUMN TABLE "WTX1" AS (SELECT ROW_NUMBER() OVER (PARTITION BY VPM2."InvoiceId",OVPM."DocNum"

ORDER BY OVPM."CardName") AS "T", VPM6."TaxbleAmnt", VPM6."WTSum", OVPM."CardCode",

OVPM."CardName", OVPM."DocNum", OVPM."DocDate", VPM6."TxblAmntFC", VPM6."WTSumFC",

OPCH."NumAtCard", OVPM."Comments", OVPM."DocTotal", OVPM."DocTotalFC", VPM2."InvoiceId"

FROM OVPM INNER JOIN VPM2 ON VPM2."DocNum" = OVPM."DocEntry"

INNER JOIN VPM6 ON VPM6."DocNum" = OVPM."DocEntry"

INNER JOIN OCRD ON OCRD."CardCode" = OVPM."CardCode"

INNER JOIN OPCH ON OPCH."CardCode" = OCRD."CardCode"

  WHERE OVPM."Canceled" <> 'y');

DELETE FROM "WTX1" WHERE "T" >1;

SELECT "T",* FROM "WTX1" WHERE "DocNum"='1004179';

DROP TABLE "WTX1";

Do i bring my drop table in the HANA query below or at the beginning? if i put it at the beginning it tells me Table not known.

Anyone who can tweak this query for me will be much appreciated.

Regards
