Cost center not getting updated in BSEG table
I posted a PO with acct assignment category K and a meterial document for the same. In the PO i have give all the details of the cost center and the GL to which it need to be posted. when I checked in the financial document, the cost center given in th PO is not getting updated in the BSEG table. When i checked for the CO document and SPL created, I found the Cost center got updated in both.
Can you please advice me on why the cost center are not getting updated in the acct doc (BSEG table) when it is given in the PO.
