Mapping with useOneAsMany

[former_member275873]

Hi All,

I am trying a scenario from Sravya' blog(/people/sravya.talanki2/blog/2005/12/08/message-mapping-simplified-150-part-ii) wherein the source structure is

Header 1..1

--MatDescr 1..1

Item 0..N

--ItemNo 1..1

--MatGroup 1..1

Target Strcutre

Header 1..N

--MatDescr 1..1

--MatGroup 1..1

--Item 1..1

-

---

ItemNo 1..1

The target strcutre will have N records for each ItemNo in source structure.

If I use the useOneAsMany fucntion then the context for MatDesc and ItemNo would be same. The context for MatDesc is HEADER but wihin the context of ItemNo, there is no such context as HEADER. How can I put the Context of ItemNo to that of MatDesc.

The structre for function mapping is:

MatDescr

ItemNo useOneAsMany MatDescr

ItemNo

Kindly let me know, how can I fill up the data in the HEADER(Target message) for each value of ItemNo.

Thanks,

Amit

Hi Amit,

<i>how can I fill up the data in the HEADER(Target message) for each value of ItemNo.</i>

Select the ItemNo field in the source. Change the context of ITemNo field in source to Header. Map the field ItemNo to Header in target.

Hi Sumit,

The context for ItemNo does not contain Header. The context contains 2 values: Item and Datatype name.

Do I need to do any more settings for the HEADER value to appear in the context of ItemNo.

Hi Amit,

<i>The context for ItemNo does not contain Header. The context contains 2 values: Item and Datatype name.</i>

I just went through the blog. Context for Item No ..Header wont be present.

Everything is explained in the blog in a wonderful way. Read the same 2-3 times u will understand.

Incase you have doubt with <b>7.useOneAsMany</b>- in the blog..then heres what you need to do..

We have 3 fields in source..

1) MatDesc - Let the context be whatever is the default one.

2) ItemNo - Change the context to Item.

3) ItemNo - Let the context be whatever is the default one.

Sumit
