Open-To-Buy Data
Merchandise planning data, in particular, Open-To-Buy (OTB), can be used by the SAP Assortment Planning for Retail application to help set planning targets.
To access OTB-related figures in SAP Assortment Planning for Retail, this data must first be imported into the DDF module in your back-end system, as described in the Integration section below. Once the OTB-related figures are available in your back-end system, SAP Assortment Planning for Retail can access this data directly as follows:
My Assortment Lists (Version 2) SAP Fiori app: When building an assortment list, you have access to summarized planned values of that assortment list's product hierarchy level and validity period.
Plan Options Workbooks: When planning options, the overall option plan monetary values are aggregated and you can compare them to the OTB-related figures.
By default, SAP Assortment Planning for Retail is configured to consume merchandise planning data from the SAP Merchandise Planning for Retail application, another add-on to the SAP Customer Activity Repository.
If you are determining the OTB using the SAP Planning for Retail, rapid-deployment solution, the OTB-related figures (KPIs including planned sales, open orders, and purchase quantities) are stored in SAP Business Warehouse (SAP BW) InfoProviders. To access these figures from SAP Assortment Planning for Retail, this data must first be imported from the SAP BW system to your back-end system, as described in SAP Note 2208191 
.
To consume merchandise planning data from the SAP Merchandise Planning for Retail application, do the following:
Verify that in the Define SAP BW Application for Merchandise Planning Customizing activity, under
