SAP package modifications

Dear Experts,

We are configuring pos to is-retail integration scenarios in PI system by using SAP Packages. But now the requirement is we have a field u201Cdescription " at target system which needs to display the data from source IDOC as per the condition - Level 1 description needs to be concatenated to the Category description of sub level. We need this requirement because of POS will accept only 3 level hierarchy.

Ex: in standard IDOC - WPDBBY01

E1WPW02-BEZEICH.Traverse the next E1WPW02 segment and check if the HIERARCHIE is 03, if yes take the value of BEZEICH and append it to the earlier E1WPW02-BEZEICH.

Thanks and Regards,

Srinivas
