EBKN-PS_PSP_PNR proviede in BI as posid

Hi,

I created a view of eban and ekbn in the sourcesystem (I didn't find something in the content).

But I have the problem, that I get WBS-element only as a numeric field in BI (comes from EBKN-PS_PSP_PNR)  for example 00010487 not like I need it for example E/000250-ERG.

Now I'm not able to work with this infromation, I need the 'external' wbs-Element.

Could somebody help me, I don't know where and how I have to do something.

Thank you in advance, Kind Regards Manuela
