I am processing contract in RE-FX system whose contract category in configuration is: External. Now when i perform the periodic posting(RERAPP), it updates customer Recon acc as well as Revenue G/L account but no updates appears in cost center. And when i am processing with Contract Category: Internal, it is updating cost center and G/L only which i have maintained in configuration, But not updates are appearing in customer recon account. Now business requirement is, they want to debit customer recon and want the values to be updated in cost center also. Please let me know what can be done for mapping it with SAP RE-FX.
