Enhancement - sales order item

Question

Hi friends,,
We have enhanced the 2lis_02_vaitm datasource with new field lfsta and gbsta(delivery status) from vbup table.
The field is populated and we are getting the values in the BW
The problem is,the changed values of delivery status is not picked.
Say, on 22th july the delivery status is pending,and the value is 'A'-pending in the gbsta field,this is coming to my bw.
The delivery is completed on 25th,and the filed value is changed to 'C'-delivery completed , when i run my delta on 26th july,the changed value is not picked,so my value 'A'-pending remains in the data target for this completed delivery..
And one of the note suggested the following suggestion to pick the delta of the user defined fields.
•     Add the required fields to the the SD communication structures using the Append method and use the LIS customer exits to fill the field.
            For information on enhancing the communication structures, see the documentation for the enhancements MCS10001, MCS50001 and MCS60001 (provided in transaction SMOD).
After you enhance the communication structures (for example MCVBAP), you can then enhance the extract structure (for example MC11VA0ITM) with the relevant field in the Customizing cockpit (transaction LBWE), provided that the comunication structure is available in the selection.
            To display a delta, you must make sure that you can determine the status in the user exit before and after the document change.
            This varies from case to case and depends on from which table the field is filled.
            For example, you may occasionally have to obtain the information from the internal document tables (such as xvbap and yvbap).
Q1.I want steps to enhance my communication structure to include lfsta and gbsta.
Q2.By doing this,will the changed values of my lfsta and gbsta will come to the bw in the delta load?
Q3.What is the meaning of the statement “To display a delta, you must make sure that you can determine the status in the user exit before and after the document change.””??
q4.How can i see the values of xvbup and yvbup table?
Thanks & regards

Answer 1

Hi Ragu
Answering your Q 1
If your data source in Non-LO cockpit:-
1. Go to RSA6, click on data source and go to extract structure.
2. In extract structure maintenance you will find Append structure button on upper right corner, click on that.
3. Name the new append structure, insert required fields.
4. Activate the structure & also activate the extract structure.
5. In LBWE go to datasource maintenance and uncheck the Hide check box for newly added fields and Save the data source.
6. Write code in user exit in CMOD to populate newly added fields.
If your datasource is LO cockpit datasource then
Option 1- Enhance in LBWE
1. check in LBWE- Maintenance -> check if your required field is available in pool (right hand side).
2. If it is available then send it to left hand side.
3. Save and you will find the new field as part of your extract structure.
4. In LBWE go to datasource maintenance and uncheck the Hide check box for newly added fields and Save the data source.
5. No need to write user exit code for these fields.
Option 2- Append & user exit code
If your required field is not available in LBWE Manitainance then follow all steps given above in "If your data source in Non-LO cockpit".
Ans for Q 2
You need to test it after enhancement of extract structre & writing the user exit code if needed.
Ans for Q3
User exit code should take  care of this. Take help from your ABAP person to do the coding.
