Map/Apply Map error

Thu, 13 Jan 2011 13:32:00 GMT

Hi,

I am trying to map one field from one table and add this field to another table by using ApplyMap.

The problem is that I have to construct a new Key using two fields from the table to be able to link the tables.

Not sure if this is possible of how to do it, but I have given it a try (see code below).

I get the following error message when I do the load for the MAP1: Field not found <t_cwar>

Anyone how knows how to do this? Thanks in advance.

Script:

// *******Inventory Value**********
ItemInventoryValue:
LOAD
"t_cwar"&'-'&"t_item" as WarehouseItem,
"t_mauc_1" as MAUC1;
SQL SELECT *
FROM erplndb.dbo.twhwmd217100;

Map1:
MAPPING LOAD "t_cwar"&'-'&"t_item" as WarehouseItem, MAUC1 Resident ItemInventoryValue;

// *******Inventory Figures*******
ItemInventory:
LOAD "t_cwar" as Warehouse,
"t_item" as ItemNo,
"t_cwar"&'-'&"t_item" as WarehouseItem,
"t_qhnd" as Inv_OnHand,
"t_qhnd"*ApplyMap('Map1',WarehouseItem,0) as OH_Inv_Value,

etc.

Hi, you need to make this change


// *******Inventory Value**********
ItemInventoryValue:
LOAD
 "t_cwar"&'-'&"t_item" as WarehouseItem,
 "t_mauc_1" as MAUC1;
SQL SELECT *
FROM erplndb.dbo.twhwmd217100;

Map1:
MAPPING LOAD WarehouseItem as WarehouseItem_MAP, MAUC1_MAP Resident ItemInventoryValue;
//The _MAP sufix it's to avoid the autoconcatenation with the 1st table

// *******Inventory Figures*******
ItemInventory:
LOAD "t_cwar" as Warehouse,
 "t_item" as ItemNo,
 "t_cwar"&'-'&"t_item" as WarehouseItem,
 "t_qhnd" as Inv_OnHand,
 "t_qhnd"*ApplyMap('Map1',WarehouseItem,0) as OH_Inv_Value,

but, i'm not following the reason you are loading the same table twice

Hi,

one thing is load only the field "WarehouseItem". It seems to be an Copy/Past error.

Map1:
MAPPING LOAD

WarehouseItem,

MAUC1

Resident ItemInventoryValue;

Where are your ApplyMap line in the script?

If I try MAPPING LOAD WarehouseItem as you suggest I get the error message: Warehouse item cannot be found.

The apply map is in the last line in table number two:

"t_qhnd"*ApplyMap('Map1',WarehouseItem,0) as OH_Inv_Value,

I have two tables:
1. Inventory value
2. Inventory quantity

I need to combine them into one and I have to use the combination of Warehouse and Item to get the right key.

Hi,

There is another problem, in the applymap you are using an alias instead of the original fields

"t_qhnd"*ApplyMap('Map1',WarehouseItem,0) as OH_Inv_Value,

replace with

"t_qhnd"*ApplyMap('Map1',t_cwar&'-'&t_item,0) as OH_Inv_Value,

The solution suggested works, but i'm not sure if the mapping table will auto-concatenate with the 1st one, because both share the same fields
