Data type Enhancement

[former_member189441]

Hi,

Can we use Data type Enhancement to extend our own Data types that are created by us or only to extend standard data type?

If so, if we extend the data type1 which is having 2 fields with Enhanced type with 1 more extra field can i use the data type with 2 fields in one mapping and data type with enhanced field in another mapping OR is it something like once if we enhanced the structure we can use only enhanced structure every where and we cant use the old data type structure??

Thanks,

Murali

Hi Abhishek,

Thanks for the clarification.

I have the DT dtructure as follows before enhancement

DT1                 occurence
   Row              0..unbound
       Field1        1
       Field2        1

After enhancing the sructure it has to act like the below structure

Structure - 1

DT1                 occurence
   Row              0..unbound
       Field1        1
       Field2        1
       Field3        0..1

when i tried to create DT enhancement in which way i have to create the Enhanced structure to replicate the above structure

Structure - 2

DT1                 occurence
   Row              0..unbound
       Field1        1
       Field2        1
DTE1
       Field3        0..1       

or

Structure - 3

DT1                 occurence
   Row              0..unbound
       Field1        1
       Field2        1
DTE1
       Row
            Field3        0..1       

Hi Abhishek,

i just mentioned the structure-1 to explain how my enhanced structure should act like..

You mean that i have to create enhanced structure as Structure-2 and it acts in the similar way of Structure-1 ?? correct me if i am wrong..

Thanks

me if i am wrong

1) You create the main Data type (DT_Main) in IR with the fields you want.

2) Due to requirement change you have to add some more fields

3) IR --> Right-click --> New --> Data Type Enhancements (DT_Enhance)

4) In DT_Enhance there will be a section where you have to select the name of the structure (DT_Main) which you want to enhance.

5) Now in DT_Enhance, you will create just one field Field_3 (occurence 0..1)

6) Save --> Activate

7) Check DT_Main .....you will find the structure as:

DT_Main                 occurence
   Row              0..unbound
       Field1        1
       Field2        1
   DT_Ehance
       Field3        0..1

Option1

Update:

You have to create a new object (Data Type Enhancements) in IR and then in there give the DT in which you want the changes to happen....also define the additional nodes in this new object and not in the original DT directly! ......just in case you want to know the procedure!

Hi

Can I use data type enhacement without create data type. For example in external definitions where I already have an xsd.

Please help

type?

Yes we can enhance the DT created in IR.

We can then see the Enhanced Data type with additional fields.......these fields can be kept optional and so you need not worry about them when you reuse the structure.
