BAPI Sales Order Create Code

Bapi Sales Order Create Code

We saw in the earlier example as to how to create a sales order from the SE37 interface. Now we need to create a program and call the BAPI to create sales orders. Later we will discuss ways to call a BAPI from a non-sap system.



Given an appropriate name to the program. Please follow the naming conventions as per your company. ABAP programs should always start with a 'Z' or a 'Y'.



Enter suitable description.



Create a $tmp objects or create a transport request. Transport requests would be covered in the later tutorials.



Follow the menu path EDIT----->Pattern



Enter the name of the BAPI as shown below.



The inserted BAPI is shown below.



We now need to get the import parameters, export parameters and the tables.
Note: Take care that the data declaration in the program for the above mentioned parameters matches exactly as given in the BAPI. To ensure that please open the BAPI using transaction SE37 and copy the exact names of the parameters from the BAPI structure.

If this is not followed your program will give an 'ABAP DUMP'.



Check the Import parameters



The following figure shows the import parameter BAPISHEAD and we need to declare a structure in our ABAP program as follows.

Data: st_BAPISDHEAD like BAPISDHEAD, " Sales Order Header Data

Make sure you follow the ABAP naming conventions.



Similarly for tables pick up the names from the function module.

Data: st_BAPISDHEAD like BAPISDHEAD, " Sales Order Header Data
ta_BAPIITEMIN like BAPIITEMIN occurs 0 with header line, " Ln item
ta_BAPIPARTNR like BAPIPARTNR occurs 0 with header line, " Partner
d_BAPIRETURN1 like BAPIRETURN1, " Bapi return msg
d_vbeln like bapivbeln-VBELN. " Sales Order Number






The complete program is given below. Please make sure that you use the data specific to your system. In the following some of the values are hard coded. You need to use variables and pick up the values.

Please note in the following program, sold to party (SP) has been entered as 'AG' and ship to party (SH) as 'RG'.

SP--------AG
SH--------RG

Order type 'OR' as 'TA'

Please use TA instead of OR

Also if you set the
* CONVERT_PARVW_AUART = 'X' parameter to 'X' you can use sold to party as SP and ship to party as SH.

REPORT ZEX_BAPISALESORDCRT .

*-------------------------Data Declaration-----------------------------*
Data: st_BAPISDHEAD like BAPISDHEAD, " Sales Order Header Data
ta_BAPIITEMIN like BAPIITEMIN occurs 0 with header line, " Ln item
ta_BAPIPARTNR like BAPIPARTNR occurs 0 with header line, " Partner
d_BAPIRETURN1 like BAPIRETURN1, " Bapi return msg
d_vbeln like bapivbeln-VBELN. " Sales Order Number


* Move the data to create sales order in the repective parameters------*
move: 'TA' to st_BAPISDHEAD-DOC_TYPE, " Sales document type
'15493' to st_BAPISDHEAD-PURCH_NO_C,
'00010' to ta_BAPIITEMIN-ITM_NUMBER,
'Y-351' to ta_BAPIITEMIN-MATERIAL,
'1100' to ta_BAPIITEMIN-PLANT,
'1' to ta_BAPIITEMIN-REQ_QTY,
'AG' to ta_BAPIPARTNR-PARTN_ROLE, " Sold to Party
'0000007777' to ta_BAPIPARTNR-PARTN_NUMB.
* Append the internal tables-------------------------------------------*
append ta_BAPIPARTNR.
clear ta_BAPIPARTNR.
append ta_BAPIITEMIN.
clear ta_BAPIITEMIN.
* Move ship to party---------------------------------------------------*
move: 'RG' to ta_BAPIPARTNR-PARTN_ROLE, " Ship to party
'0000007777' to ta_BAPIPARTNR-PARTN_NUMB.
* Append the internal tables-------------------------------------------*
append ta_BAPIPARTNR.
clear ta_BAPIPARTNR.


* Call the Bapi to create the sales order

CALL FUNCTION 'BAPI_SALESORDER_CREATEFROMDAT1'
EXPORTING
ORDER_HEADER_IN = st_BAPISDHEAD
* WITHOUT_COMMIT = ' '
* CONVERT_PARVW_AUART = ' '
IMPORTING
SALESDOCUMENT = d_vbeln
* SOLD_TO_PARTY =
* SHIP_TO_PARTY =
* BILLING_PARTY =
RETURN = d_BAPIRETURN1
TABLES
ORDER_ITEMS_IN = ta_BAPIITEMIN
ORDER_PARTNERS = ta_BAPIPARTNR
* ORDER_ITEMS_OUT =
* ORDER_CFGS_REF =
* ORDER_CFGS_INST =
* ORDER_CFGS_PART_OF =
* ORDER_CFGS_VALUE =
* ORDER_CCARD =

* ORDER_SCHEDULE_EX =
.

if d_vbeln <> space.
write: 'Sales order No. ', d_vbeln.
endif.

 ABAP TIPS


Since your web browser does not support JavaScript, here is a non-JavaScript version of the image slideshow:

 ABAP TIPS
Always specify your conditions in the Where-clause instead of checking them yourself with check statements. The database system can then use an index (if possible) and the network load is considerably less.


 ABAP TIPS
For all frequently used Select statements, try to use an index. You always use an index if you specify (a generic part of) the index fields concatenated with logical Ands in the Select statement's Where clause. Note that complex Where clauses are poison for the statement optimizer in any database system.


 ABAP TIPS
If there exists at least one row of a database table or view with a certain condition, use the Select Single statement instead of a Select-Endselect-loop. Select Single requires one communication with the database system, whereas Select-Endselect needs two.


 ABAP TIPS
It is always faster to use the Into Table version of a Select statement than to use Append statements.


 ABAP TIPS
To read data from several logically connected tables use a join instead of nested Select statements. Network load is considerably less.


 ABAP TIPS
If you want to find the maximum, minimum, sum and average value or the count of a database column, use a select list with aggregate functions instead of computing the aggregates yourself. Network load is considerably less.


 ABAP TIPS
If you process your data only once, use a Select-Endselect-loop instead of collecting data in an internal table with Select Into Table. Internal table handling takes up much more space.


 ABAP TIPS
Use a select list or a view instead of Select * , if you are only interested in specific columns of the table. Network load is considerably less.


 ABAP TIPS
For all frequently used, read-only tables, try to use SAP buffering. Network load is considerably less.


 ABAP TIPS
Whenever possible, use array operations instead of single-row operations to modify your database tables. Frequent communication between the application program and database system produces considerable overhead.


 ABAP TIPS
Whenever possible, use column updates instead of single-row updates to update your database tables. Network load is considerably less.


 ABAP TIPS
Instead of using nested Select loops or FOR ALL ENTRIES it is often possible to use subqueries. Network load is considerably less.


 ABAP TIPS
Use the special operators CO, CA, CS, instead of programming the operations yourself. If ABAP/4 statements are executed per character on long strings, CPU consumption can rise substantially.


 ABAP TIPS
Some function modules for string manipulation have become obsolete and should be replaced by ABAP/4 statements or functions: STRING_CONCATENATE... -> CONCATENATE, STRING_SPLIT... -> SPLIT, STRING_LENGTH -> strlen(), STRING_CENTER -> WRITE...TO...CENTERED, STRING_MOVE_RIGHT -> WRITE...TO...RIGHT-JUSTIFIED


 ABAP TIPS
Use the CONCATENATE statement instead of programming a string concatenation of your own.


 ABAP TIPS
If you want to delete the leading spaces in a string, use the ABAP/4 statement SHIFT...LEFT DELETING LEADING... .Other constructions (with CN and SHIFT...BY SY-FDPOS PLACES, with CONDENSE if possible, with CN and ASSIGN CLA+SY-FDPOS(LEN) ...) are not as fast. In any case, avoid using SHIFT inside a WHILE-loop!


 ABAP TIPS
Use the SPLIT statement instead of programming a string split yourself.


 ABAP TIPS
Use the strlen( ) function to restrict the DO loop to the relevant part of the field, e.g. when determinating a check-sum.


 ABAP TIPS
Use "CLEAR f WITH val" whenever you want to initialize a field with a value different from the field's type-specific initial value.


 ABAP TIPS
Try to keep the table ordered and use binary search or used a table of type SORTED TABLE. If TAB has n entries, linear search runs in O( n ) time, whereas binary search takes only O( log2( n ) ).


 ABAP TIPS
A dynamic key access is slower than a static one, since the key specification must be evaluated at runtime. However, for large tables the costs are dominated by number of comparison needed to locate the entry.


 ABAP TIPS
If you need to access an internal table with different keys repeatedly, keep your own secondary indices.With a secondary index, you can replace a linear search with a binary search plus an index access.


 ABAP TIPS
LOOP ... WHERE is faster than LOOP/CHECK because LOOP ... WHERE evaluates the specified condition internally. As with any logical expressions, the performance is better if the operands of a comparison share a common type. The performance can be further enhanced if LOOP ... WHERE is combined with FROM i1 and/or TO i2, if possible.


Always use Pretty Printer and Extended Program Check before releasing the code. Do not leave unused code in the program. Comment the code thoroughly. Align the comments and the Code. Follow the SAP Standards and SAP Best Practices guidelines. It’s a good practice to take a dump of the code on your local drive.
