Reading Target field Values in Mapping Runtime

[sahana_ps]

Hi all,

I have a requirement ,

source                target

A                           X

B                           Y=X+Z+W

C                           Z=X+Y

D                           W

Kindly can some one help me,how this can be achived in mapping?

source                target

A                           X

B                           Y=X+Z+W

C                           Z=X+Y

D                           W

source                target

A                           X->A

B                           Y=X+Z+W->A+A+D+D

C                           Z=X+Y->A+D

D                           W->D

Hi Sahana,

This might sound lil wierd but there is another way of handling this situation. Use three different Message mapping and club them in operation mapping.

In first mapping just map X and W field.

In second mapping map Z field and in third one map the Y field.

this is quite simple solution.

thanks and regards,

Hi,

are you sure about that ?

B                           Y=X+Z+W

C                           Z=X+Y..... so Z=X+X+Z+W    !!!!!    so 2X = -W... (in mathematic) 

does "+" is "add" or "concatenate"?

Else as X comes from A, W comes from D... in your mapping use the sources A and D, and do not try to use your targets... Or if you have have to the same value, reuse the rule ! and point it to two target fields

Hi Sahana,

You can achieve your goal with value-mapping, where the X, Y, W, Z  will be stored in configuration time. Later you only need to concat the results in the message mapping for B and C source mapping.

In this wiki you have an easy how-to http://wiki.scn.sap.com/wiki/display/XI/Value+mapping

Also, you can check this document http://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/library/uuid/00ee347e-aabb-2a10-b298-d15a1ebf4...

Regards.
