Hi Ömer,
I am curious on which source system and plug-in release you are. I am on SAP_APPL 6.06 and PI_BASIS 7.31. In my system the DataSource looks as follows:
The Transfer Method is in my case 3: PSA and IDOC. It might be different in your case.
Please have a look at SAP Note 1313068 - tRFC transfer of pure IDoc hierarchies to PSA and implement it if necessary.
Anyway, I found for your reference another Hierarchy DataSource 0MATERIAL_LPRH_HIER with Transfer Method 1: IDOC Only. This should be more familiar to your case.
Please have a look at the following screenshot:
You can observe that I also used rule type Hierarchy Split in this case. However, the difference is the handling of IOBJNM.
If you have loaded your data in the PSA and you analyze segment Hierarchy Nodes, then you will observe the Business Content Characteristics 0CO_AREA and 0COSTELMNT. You will have to intervene here: replace the Business Content Characteristics by your custom Characteristics.
You have to create a small routine with coding like this:
case source_fields_3-iobjnm.
when '0CO_AREA'.
result = 'ZCO_AREA'.
when '0COSTELMNT'.
result = 'ZCOSTELMNT'.
when others.
result = source_fields_3-iobjnm.
endcase.
I hope that this will be sufficient to let it work in your case. If not, please let me know.
Best regards,
Sander
