QVD file not loading when combined with mapping tables

Thu, 21 Nov 2013 06:24:48 GMT

Hi,

In data model script, I created two Mapping tables:

1) ProdColorPrimary:

MAPPING LOAD

%PRODUCT_KEY, RGB(Red,Green.Blue)

from ..\ProdColorPrimary.xlsx

2) ProdColorSecondary:

MAPPING LOAD

%PRODUCT_KEY, RGB(Red,Green.Blue)

from ..\ProdColorSecondary.xlsx

Then I tried to loaded PRODUCT.QVD file with new field (%PRODUCT_KEY) from this mapping table following syntax given below:

3) PRODUCT:

LOAD DISTINCT

DW_PRODUCT_FAMILY_ID as %PRODUCT_KEY,

MARKET_NAME AS [Market],

AT_PROMO_FLG,

DISPLAY_PRODUCT_GROUP_NAME AS Product,

applymap('ProdColorPrimary',%PRODUCT_KEY,RGB(128,128,128)) as PrimaryColor,
applymap('ProdColorSecondary',%PRODUCT_KEY,RGB(0,128,255)) as SecondaryColor

          FROM
          Data\PRODUCT.qvd (qvd)
          WHERE exists(%PRODUCT_KEY,DW_PRODUCT_FAMILY_ID)

While loading these files, I below following error.

[ Error:

Field not found - <%PRODUCT_KEY>

PRODUCT:

LOAD DISTINCT

DW_PRODUCT_FAMILY_ID as %PRODUCT_KEY,

MARKET_NAME AS [Market],

AT_PROMO_FLG,

DISPLAY_PRODUCT_GROUP_NAME AS Product,

applymap('ProdColorPrimary', %PRODUCT_KEY, RGB(128,128,128)) as PrimaryColor,
applymap('ProdColorSecondary', %PRODUCT_KEY, RGB(0,128,255)) as SecondaryColor

          FROM
          Data\PRODUCT.qvd (qvd)
          WHERE exists(%PRODUCT_KEY,DW_PRODUCT_FAMILY_ID)

]

The Product table is not loaded in application. In my mapping tables I have %PRODUCT_KEY present only for products which has specific colors defined. The colors for which default colors needs to be used is not defined in these mapping tables.

Kindly help me in understanding the issue.

Does commenting WHERE exists(%PRODUCT_KEY,DW_PRODUCT_FAMILY_ID) would help?

Please suggest.

Thanks !

Hi,

Try this.

PRODUCT:

LOAD DISTINCT

DW_PRODUCT_FAMILY_ID as %PRODUCT_KEY,

MARKET_NAME AS [Market],

AT_PROMO_FLG,

DISPLAY_PRODUCT_GROUP_NAME AS Product,

applymap('ProdColorPrimary',DW_PRODUCT_FAMILY_ID,RGB(128,128,128)) as PrimaryColor,
applymap('ProdColorSecondary',DW_PRODUCT_FAMILY_ID,RGB(0,128,255)) as SecondaryColor

          FROM
          Data\PRODUCT.qvd (qvd)
          WHERE exists(%PRODUCT_KEY,DW_PRODUCT_FAMILY_ID)

You can not use the new field name in same load statement, so use the original field name.
