Hi Indrashis,
For each Billing doc , there will be Multiple Condition Documents.
Means, each record in 13_VDHDR or VDITM will have multiple Condition Docs.
Even if you enhance 11 VAITM with KNUMV field(Doc. condition) , you will not get all condition docs.
Because of this you have 2LIS_13_VDKON datasource.
That’s what I told you in above, for each record in VBRK, you will get multiple records in KONV.
VBRK - KNUMV
Pass KNUMV into KONV Table and get Condition Value (KWERT ).
