PSCD_TRM_RETURN_PROCESSING: BRF Tax Validation/Calculation (New)

Use

As of SAP ECC 6.0, Industry Extension Public Sector, Enhancement Package 03 , Business Function TRM: Return Processing (PSCD_TRM_RETURN_PROCESSING), you can use the Business Rules Framework(BRF) to map rules for the validation and calculation of object-based and form-based taxes in the system. For object-based tax, the tax liability constitutes an object (such as, vehicle tax). Taxes for which the taxpayer has to submit a tax return (such as income tax) are known as form-based taxes. The BRF is called in the single and mass transactions for calculating object and form-based tax and also for the validation of forms from the application for processing tax returns. Information on the latter can be found in the release information PSCD_TRM_RETURN_RROCESSING: Processing Tax Returns (New).

Each application used in the BRF is assigned to an application class. This ensures that different applications do not affect each other.

SAP delivers the following application classes that contain all implementing classes that you can use for the tax validation and calculation.

TRM_TEMPLATE_FORM for form-based tax

TRM_TEMPLATE_OBJECT for object tax

TRM_TEMPLATE_OBJECT_TIME for object tax with time-dependent data

You can copy these implementing classes into your own application classes in IMG activity Copy Implementing Classes. The name of the implementing classes in the following list are the names in the application classes delivered.

In addition to the expression and action types that are available in the BRF as standard, there are a number of additional functions that you can use.

Context Information

When calling the BRF for the tax calculation, the system writes the data that it needs for the calculation and validation in a buffer by default which you can access. You can also load more data from each table to the context buffer. You can then access this data the same way.

Container of the context is an event. To define events in Tax and Revenue Management (TRM) always use the implementing class 0FICAEVENT.

Actions

Actions map manipulations of datasets and are used to map rules in the BRF. SAP delivers the following actions for tax validation and calculation that you can use as well as the actions that are available in the BRF as standard.

Description of Action	Implementing Class
Get context data	0FICAIN001
Create billing document	0TRMBI001
Create additional item of billing document	0TRMAI001
Set block	0TRMSL001
Issue message	0TRMMSG001
Create inbound correspondence request	0TRMIC001
Set date of receipt	0TRMSR001
Define form rules	0TRMFO001
Define values for revenue distribution	0TRMRD001
Implicit registration	0TRMIR001
Start workflow	0TRMWF001

Expressions

In an expression, data of the application or data of objects related to the application (for example, business partner data) are processed in accordance with a rule (such as a calculation rule) you can define yourself. Once the system has processed the data, the expression returns any primitive type (such as a date) as a result. SAP delivers the following expressions for tax validation and calculation that you can use as well as the expressions that are available in the BRF as standard.

Description of expression	Implementing class
Calculate
charges	0TRMPEN001
Calculate interest	0TRMIN001
Read fact value	0TRMRF001
Request from/to date of a period	0TRMRP001
Request XML value	0TRMRX001
Gradual calculation	0TRMPC001

Time-dependent expressions

You can create expressions that are time-dependent, this means that they return different values for different time segments (time slices). Implementing classes available as standard in the BRF were copied and enhanced for this so that they provide time-dependent return values. The following implementing classes for time-dependent expressions are available for this.

0TRMAO001 (and/or of Boolean expressions)

0TRMFM001 (calling a function module)

0TRMCE001 (CASE expression)

0TRMPM001 (truth tablle)

0TRMAO001 (Boolean expression with three variables)

0TRMFB002 (SAP formula interpreter)

0TRMRE001 (range expression)

If you use an expression with implementing class 0TRMTSM001, you can multiply a value by the length of the time slice in which it is valid. Define the corresponding time unit for this (for example, month or year).

With an expression with implementing class 0TRMTSA001, you can use time slices to aggregate, for example, map the total of all time slices. The return value of the expression is then no longer time-dependent.

If you use a time-dependent expression in the action when creating billing documents, you can create your own billing document for each time slice.

Events

Events P300 and P301 are available when creating additional items for the billing document. For more information, see the documentation on the sample function modules.
