In my pay load we have multiple TDID=Z001 for TDLIE's are in only 2nd and 7th line item level only.
we need to concatenate these TDLINEs and pass to the 2nd & 7th line item level in target.
Note: we may not get any TDLINEs also like 1st line item level then we don't need to pass anything to target in first line item level.
