Sales Inquiry

[Former Member]

Hi all,

I am working on a research project on implementing Multi-agents into a SAP R/3 system using abap.

I am new to abap and want to know a few things.

I have taken a small business transaction of creating a sales inquiry.

I am trying to display VBAK table using selection-screen statments. for eg:

tables: VBAK.

selection-screen begin of line.

selection-screen comment (33) text-001.

parameters: 001 like VBAK-VBELN.

selection-screen comment (33) text-002.

parameters: 002 like VBAK-vkorg.

selection-screen end of line.

it is giving me error which says: the field "002" cannot be changed. -

<b>Please let me know if this is the right approach to access the tables and insert data into them.</b>

Thanks,

Apurv.

Jawle,

Give some name to the parameters and that error will not come.

Something like p_vbeln.

Jawle,

That was about the parameter.

You can use SELECT statements to fetch the data into internal tables. <b> You should never update / insert / delete of the tables in SAP.</b> There are some BAPI's that will be provided, you should do any updation only using those.

Thanks Ravi,

Is there any BAPI documentation from where I can implement those for the updation of data base?

Jawle,

Go to the BAPI transaction and choose SALES and DISTRIBUTION and under that you will be able to see the functions / BAPI pertiaining each business object.
