Hi ,

For eg : go for this BAPI: in se37

BAPI_SALESORDER_CHANGE

Short text

Customer Enhancement for VBAK, VBAP, VBEP

Description

You can use this parameter to transfer user-specific enhancments to a

BAPI. The customer has to complete the EXTENSION structure and the

system automatically continues processing it. If you have not defined

any user-specific fields, then you can transfer a blank EXTENSIONIN

structure.

Technical Information about Customer Enhancements

The following description uses an example to explain how to proceed with

customer enhancements to the SD tables VBAK, VBKD, VBAP and VBEP.

The customer has added their own fields to table VBAP using the INCLUDE

structure CUTEST. This structure contains 2 fields:

CFIELD1, CHAR 10

CFIELD2, CHAR 3.

The customer also requires that these two fields can be maintained with

the BAPI.

1. Maintain structure CUTEST in table VBAP

2. Because the BAPIs work with checkboxes, you must also define a

Field name Data element

CFIELD1 CHAR1

CFIELD2 CHAR1

3. Define these customer structures in the structures VBAPKOZ und

VBAPKOZX using INCLUDE or APPEND.

4. Add the customer structures to the BAPE_VBAP and BAPE_VBAPX BAPI

structures using the APPEND technique.

5. Adjust the following structures for customer enhancements to table

VBAK:

a) VBAKKOZ

b) VBAKKOZX

c) BAPE_VBAK

d) BAPE_VBAKX

6. Adjust the following structures for customer enhancements to table

VBEK:

a) VBEPKOZ

b) VBEPKOZX

c) BAPE_VBEP

d) BAPE_VBEPX

7. Generally, the data should be added to the BAPI interface in the

internal communication structures (VBAKKOM, and so on). There, you can process the data in the SD tables (VBAK, and so on).

8. If the EXTENSIONIN parameter contains customer data, you must

complete at least the key fields in the relevant standard

parameters.

For example:

You want to change customer field VBAP-CFIELD2 for item 20 to "XYZ" in

order 4711.

The following entries are expected:

Import: BAPIVBELN-VBELN = '0000004711' Document number

BAPISDHD1X-UPDATEFLAG = 'U' UPDKZ for doc header

Tables: BAPISDITM-ITM_NUMBER = '000020' Item number

BAPISDITMX-ITM_NUMBER = '000020' Item number

+ BAPISDITMX-UPDATEFLAG = 'U' UPDKZ for item

You must complete the EXTENSION table as follows:

STRUCTURE VALUEPART1 1234561234567890123

BAPE_VBAP 0000004711000020 XYZ

BAPE_VBAPX 0000004711000020 X
