SAP Treasury, just like any other applications from FSCM (Financial Supply Chain Management), works with Business Partners. If Business Partners are not yet implemented in your ERP, one of the first tasks of any SAP Treasury implementation project might be to implement those Business Partners master data.
Business Partners can either be created manually from scratch (using transaction BP for example) or from customers and / or vendors master data (using transactions FLBPD1 – Create Business Partner from Customer and FLBPC1 – Create Business Partner from Vendor). In this latter case, a logical link will be established between the Business Partner and the corresponding customer or vendor master data. Note that in case this link would not be created initially (because the Business Partner is initially created manually from scratch or because the Business Partner is created before the corresponding customer or vendors master data), it can still be created at a later stage using transactions FLBPD2 – Link Business Partner to Customer and FLBPC2 – Link Business Partner to Vendor.
Business Partners are role-based. SAP Treasury relies on Business Partner role TR0151 (Counterparty) to define general settings of the partners as well as so-called standing instructions.
From a Treasury perspective, key general information includes the partner identification data, its address and its bank account information.
Standing instructions are key company code dependent settings affecting how partner’s payments and correspondence should take place and defining what Treasury transactions are allowed with the partner and what derived flows should be applied (typically used to compute and post tax amounts on interests earned).
