Query on Implicit Enhancement

[Former Member]

Hello experts,

I have a query related to enhancing a function module. I am doing phase confirmation of process orders using the BAPI 'BAPI_PROCORDCONF_CREATE_TT' in a module pool program(Z program). I have added few z fields to AFRU. Now i need to enhance the bapi 'BAPI_PROCORDCONF_CREATE_TT' so that the z fields are updated in AFRU. In this bapi i see a function module MAP2I_PI_TIMETICKET_TO_AFRUD in which the z fields can be moved to afrud using an implicit enhancement. But the problem is that the function module MAP2I_PI_TIMETICKET_TO_AFRUD is auto generated and there is a comment in the fm saying 'Dont Change it Manually!!'. Now i need to know how is this function module generated or is there any other way to do phase confirmation of process orders. Pls Help.

Hello,

I think you can enhance this Function Module MAP2I_PI_TIMETICKET_TO_AFRUD by creating an implicit enhancement Implementation and add the Z-Fields of yours at the end which will not have any impact on the generated code.

Hope this helps.

Hi

I think you can enhance the function module , as implicit enhancement does not effect SAP standard . We are not changing the SAP standard, it falls into custom development.

well you CAN enhance it.

But once done, save what you got, since when it get generated again, your work will be lost.

Hi Florian,

I thought the implicit enhancement were kept even when its hooked object is deleted (as they are independant, they are hooked only at runtime), so I did a test with BDBS to be sure, and it's still there (I use 7.0 sp 13)

Hi Sandra rossi,

Thanks for the helpful response. Can you give me some more explanation on how you checked it?

Thanks in advance.

Hi Ramanan R.S.,

Function modules MAP2I* and MAP2E* are generated via BDBS transaction.

As your function module is named MAP2I_PI_TIMETICKET_TO_AFRUD, it means that there's a transfer from external to internal (because of MAP2I), and from PI_TIMETICKET structure to AFRUD structure.

But I don't recommend that you work with this one. Create your own MAP2I function module. From BAPIRET2 to BAPIRETURN for instance if you're lazy like me. Store it in your own Z function group, local package.

Before regenerating, you have to look at what was the initial mapping, as it is not stored in a database table, only in the source code. Moreover, it's possible that there were some manual changes before, so they have to be applied manually, so that means a modification of standard if you had worked on a standard one. Copying the MAP2I function module to a Z one before deleting is a very good idea!

- Create your implicit enhancement. Test it.

- In BDBS, you enter transfer from external to internal, plus these 2 names in BDBS, click Generate button.

- It says "already exists", so you have to click the Delete button

- There could be a popup "is still used", click Delete to confirm

- It proposes a default mapping between fields, that can be different from what was previously done.

- That will regenerate the function module (you can make sure by looking at its timestamp).

- Test it again, you'll see that your implicit enhancement is still there.

I admit it doesn't test the situation of a true upgrade, and I don't know any documentation that confirms that the deletion of generated repository object doesn't impact its implicit enhancement. Feedbacks welcome...
