I am facing one problem while saving PO in SRM.
Firstly, i get the po details using FM 'BBP_PD_PO_GETDETAIL'
Then, i update one header field.
Then, i pass the header to the FM 'BBP_PD_PO_UPDATE'
After that i am using 'BBP_PD_PO_SAVE' by passing the guid.
Lastly, I am using 'commit work and wait'.
But, when i check the PO that field is not updated.
I am not getting where things are going wrong..
