I have the same problem: app shows me always 0s as items number but when I click on hyperlink-ed 0's I see the associated documents.
I applied the note 2151498 - W2/ SP06/SP07 corrections for the app MM_PURDOC_LIST 'My Purchasing Document Items' without success.
Debugging "PDOCITEM_GET_ENTITYSET" method of "CL_ME2STAR_OD_DPC_EXT" class relative to odata service "/sap/opu/odata/sap/ME2STAR_OD_SRV/PDocItem", I noticed a selection query on "CDS_M_M2S_PD_ITM" view to get CNTF, CNTK, CNTL fields. All the fileds return 0 as value. No OSS note found on SAP portal regarding it.
Any idea how to solve it? Does it need to open an OSS note?
Thanks so much
Luca
