          T1.ARTICLE_ID = T2.ARTICLE_ID;

  var_out = SELECT ARTICLE_ID,CATEGORY,SALE_PRICE,COLOR_CODE,AMOUNT_SOLD,FAMILY_NAME FROM :JOIN1;

OUT3 = SELECT ARTICLE_ID,COLOR_CODE,CATEGORY,FAMILY_CODE FROM "vinoth"."ARTICLE_COLOR_LOOKUP";

And what exact error message do you get?

Some things what can be seen from the code:

• The last three statements are not closed with a semi-colon (JOIN2 = ...; var_out = ...; END;).
• The select for JOIN2 refers to T3.FAMILY_CODE. But this table (T3 aka JOIN1) has no such column. It has just a column FAMILY_NAME.

Hi,

I think your problem is that T3 don't have FAMILY_CODE, the X does (see bold).

JOIN2 = SELECT T3.ARTICLE_ID,T3.COLOR_CODE,T3.CATEGORY,T3.FAMILY_CODE

  FROM

  :JOIN1 AS T3

  LEFT OUTER JOIN

  :OUT3 AS X

  ON

  T3.ARTICLE_ID=X.ARTICLE_ID

  var_out = SELECT ARTICLE_ID, COLOR_CODE,CATEGORY,FAMILY_CODE
