Arvind,
I understand your requirement...
I have gone through datasource 2LIS_04_PKKANBAN but couldn't find many fields of table PKHD in this DS. i.e PKNUM,PRVBE,-PKSTE.
In my earlier post i was talking about only the 2LIS_04_PKKANBAN data source.
Rest of the data source which i had mentioned can be used as it is... only enhance the above data source with the business required fields.
In the above 3 field PRVBE already part of data source, for rest 2 fields you need to enhance the data source.
Hope its clear now... let me know if you need more info.
Regards
KP
