We just recently went live with SAP HANA version. i have noticed that when i create a document using FB01 or FBV1 and enter a CC different to the OKB9 default, the system overwrites and replaces it with the OKB9 CC. this was never an issue with ECC 6 version. i have checked for any substitutions or user exit and there is nothing. does anyone know why this is happening and if we there is anything else we can do to fix this?
