Retrieve all versions of a PO

Hi All,

Please let me know Table of Function Module to retrieve all the versions of a SRM Purchase Order, i.e GUID and its corresponding version number.

(i.e If a PO is changed and approved multiple times then we can see all the versions in t-code BBP_PD. )

I tried FM BBP_PD_PO_GETDETAIL, the output internal table E_VERSION returns only one version of the document.

Thanks,

Sameer Tapre.
