Formulas used must be written in AdvPL syntax for the system to interpret them.

Procedures

Creating formulas:

Indication of a field from another file

• • Formula:

SE1->E1_Valor = value of currency 1 from SE1 - Bills Receivable File.

Operation between fields or fixed parts (alphanumeric)

Used to set data by gathering information that is in different fields or with a part considered fixed. Its complement is referenced by the name of a field.

• • Formulas:

LEDGER ACCOUNT = SA1->A1_CONTA + SE1-> E1_NATUREZ

HISTORY = “Concerning a trade note payment” + SE1->E1_NUM

Mathematical operations with or without condition are used to obtain a value represented in several fields, as well as some information whose mathematical formulas must be applied to a certain field.

• • Formulas:

SALES PRICE =

IIF(DAY(Dbase)=15,B1_PRV2*0,10,B1_PRV1)

TOTAL OF COMMISSION PAID TO A BILL =

(SE1->E1_COMIS1+SE1->E1_COMIS2+SE1->E1_COMIS3+ SE1->E1_COMIS4 + SE1->COMIS5)

Operation with UserFunction and system fields.

Practical Application

Use of the field Term Formula of product register to create a UserFunction.

...

UserFunction FORMPRZ()

Return

2. In Formula Register, a userfunction must be associated with a formula to calculate the delivery term:

...

Code

...

001

...

Description

...

Delivery Term Formula

...

Formula

...

EXECBLOCK("FORMPRZ",.F.,.F.)

At this moment, the userfunction is run for test (validation). If there is any inconsistency, the formula cannot be saved.

3. After registering the formula, the userfunction must be changed to define how the delivery term is calculated. Example:

UserFunction FORMPRZ()

// The minimum delivery term for every 100 units is the period entered in

...

Return Max((QUANTITY/100)*SB1->B1_PE,SB1->B1_PE)

4. In the Delivery Term  field, enter the code of the formula registered, in this case 001.
