Function Modules...In SAP CRM

[Former Member]

Hi,

In SAP CRM 5.0 i observed that there are different types of standard function modules available.

Some FM names are ended with ...OW , EC, etc(i,e CRM_ORDER_I_MAINTAIN_MULTI_OW etc )....I just want to know what is the significance of this type of FMs. Like this if any other such FMs are also exists then please share.

It would be great if anybody can explain me about the above.

Thanks

Hi Sudhansu,

This is related CRM one order concept.

CRM Order is consisted by following four layer.

And each have specified function module

Layer short Long

-UserInterface Layer UI UserInterface

-Interaction Layer IL Interaction Layer

-Object Layer OB Object Buffer

OW Object Workarea(?)

-Database Layer DB Database Buffer

DU Database update

And other function has specified name also.

Other short Long

-Event EC Event Call

-Customizing Data CB Customizing Buffer

-Archive AC Archive

...

If you develop BAdI, you should use the FM on Object Layer because of

to keep data consistansy.

Hi Masayuki,

Thanks for the info. It would be great if you can explain how these layers are interlinked. And how one can decide which FM of these layers to use in different scenarios?

If you have any document related to this then please share!
