Trade Spends and Dates 
Trade promotion date ranges are used to track the dates of specific activities relating to the trade promotion.
You can perform the following tasks:
Associate a date range to a trade spend combination so that the Date Range field is automatically filled in a new trade promotion once the trade spend values are populated.
Automatically pre-populate trade spends and set default values for the start and end date of the trade spend in trade promotion planning
Add a product, product category, product group, or product segment, and specify effective dates
Effective dates can be different from the trade promotion start and end buying dates. You can also define default date ranges for the effective dates.
Add a trade spend and a trade spend exception to a trade promotion and specify start and end dates
A trade spend exception is a trade spend that is specific only to a product, product category, or product group. By default, the trade spend start date is the Effective From date and the trade spend end date is the Effective To date.
In Customizing for Customer Relationship Management (CRM) you have performed the following tasks:
Defined additional date ranges by choosing
Related a combination of spend type, spend category and spend method to a date range by choosing by choosing Relate Date Range
Defined if you want the trade spend date information pre-populated in trade promotion planning by choosing by choosing Spend Method, Take Rate, Off Invoice Cap and selecting the pre-populate indicator
Defined if you would like to integrate funds management functions by mapping the relevant expense type to the trade spend by choosing
Defined default date ranges for the effective dates by choosing
Trade spend dates are defaulted automatically to new trade promotions when the dates maintained for the trade promotion in the Dates assignment block are within the date range related to the trade spends in Customizing.
The Date Range for the trade spends in the planning page is defaulted after the trade spend values have been selected if the date range has been related to a trade spend in Customizing.
If no customizing has been done, the system searches for the Buy or Plan date range. Otherwise, it is left blank and can always be modified.
Note
Data is only pre-populated when initially creating the trade promotion. If you delete the default data, you must manually maintain it.
You can also use this function for deals.
You can add a product, trade spend, or a trade spend exception to a trade promotion even if it has the status Released.
You can also add a product retroactively to a released trade promotion. However, you cannot add an off-invoice trade spend retroactively.
You withdraw a product or a trade spend from a trade promotion by specifying an end date that is earlier than the trade promotion buying end date.
Note
The product or trade spend becomes read-only and you cannot add it again.
You must regenerate conditions manually at the product level to reflect the new end date. The planning grid in SAP NetWeaver Business Intelligence (SAP NetWeaver BI) is updated. If the effective to date is between a planning period, an average trade spend is shown based on prorating.
You can include additional date ranges to your trade promotion in the Dates assignment block.
If you change the dates in the Dates assignment block for the trade promotion, and you have not modified any of the dates in the Planning assignment block, then the changes will be synchronized to the trade spends automatically.
