variable function part

Definition

The variable function part, which depends on the

indicator for step , can have the following meaning:

P - Plausibility checks

You can enter values for specific infotype fields. Field names must be entered in full. Literals and constants can serve as comparison values. These must be enclosed by inverted commas. Variables can also be used.

The old value of a field can be used for comparison; the field name must be preceded by PSAVE-.

If fields of other infotypes are used for comparison, these must be stored in the module pool of the current infotype.

The following comparison operators are supported:

Consecutive checks must be linked by a logical AND. Logical OR links must be indicated by a /X.

If the result of the comparison operation is not "true", then the following commands (I, F, W etc.) are skipped over until a field is reached or a new comparison operation takes place.

Examples
Infotype Field ..... Ind. Variable function part
0007 STAT3 P PSAVE-STAT3='1'
The step is taken if the value in the P0007-STAT3 field changes from 1 to 0.
0007 P P0013-ALVKZ<>'0'/X
0007 P P0013-RVKZ1<>'0'/X
0007 P P0013-RVNUM=SPACE
The first three conditions are linked by an OR; at least one of these conditions must be met. Condition 4 must always be met.
The step is taken if the following holds true:
P0013-KVKZ1 not equal to 0 or P0013-ALVKZ not equal to 0 or P0013-RVKZ1 not equal to 0, and P0013-RVNUM empty.

I - Maintain infotype record

Enter the step, infotype, subtype, object ID, start and end dates of the record and an indicator which defines whether the step is to be run in the background.

Use commas to separate selection criteria just like the separator in the matchcode. If an entry is missing, the system inserts a comma.

Separate the indicator for suppressing dialog from other entries by a slash.

Constants, such as those for subtypes, are not enclosed in inverted commas.

Variable entries are also permitted. Fields containing such values must be put in brackets.

Examples

:

Infotype Field .... Ind. Variable function part
Step: Create a Dates record, subtype 01, run in the background
Step: Delete Rec. Payments/Deds. record with subtype (wage type) M559.
Step: Create a Basic Pay record (0008) without subtype and object ID. The start and end dates are the same as those in the current Planned Working Time record (0007); specify these two fields only if they are filled because the dynamic action was triggered by this infotype.

W - Default values for new record

Literals or variables are used as default values.

Set the defaults for the infotype, subtype, object ID, start and end dates using an I step and not a W step.

Do not set defaults for Q fields of an infotype because the values for these fields are derived from the corresponding P fields.

Examples
Infotype Subtype ..... FC Ind. Variable function part
0021 2 04 W P0015-BETRG='10000'
When a Family/Related Person record (0021) record with subtype 2 (child) is created, an Additional Payments record (0015) with a default amount of 100.00 is created.

V - Cross-reference to another step

Here, you can combine fields to groups. The variable function part contains the value in the field which follows the "field" column. Steps which are specified only for the following field are also triggered for each of the other fields.

Examples
Infotype Field ..... FC Ind. Variable function part
0016 PRBZT 06 I DEL,0019,01/D
Infotype 0019, subtype 01 is deleted in the background when the field PRBZT or PRBZH in infotype 0016 is changed or created (function code 06).
The following entries are equivalent:
0016 PRBZT 06 I DEL,0019,01/D

F - Call a routine

You can call internal (module pool) as well as external routines.

If you call external routines, type the program name in brackets after the routine name. Do not specify 'using' parameters. When calling an external routine, all data must be declared in a common part. You can use the fields of structure RP50D to return values from the routine. These are not used in the standard system and can only be populated via the routine and then can be used for defaults (W-Commands).

This allows customer-specific routines to be formulated with all the above steps.

Example

1:

0016 PRBZT I INS,19,01
0016 PRBZT W P0019-VTRMN=PRBEND
Module pool MP001600 contains the PROBATION routine. This routine uses the entries in the fields P0016-PRBZT and P0016-PRBEH to determine the end of the probation period which it stores in the field PRBEND.
The system creates a new 'Dates' record with the reminder date = PRBEND.
Example

2:

Infotyp ..... Ind. Var. function part
0001 F GET_DATE(ZPUDYN01)
0001 I INS,19,01
0001 W P0019-VTRMN=RP50D-DATE1
The GET_DATE routine in program ZPUDYN01 calculates a date and enters this date in the RP50D-DATE1 field via "TABLES RP50D" in ZPUDYN01. This date can be user-defined in GET_DATE: if necessary, user-defined infotypes can be read afterwards.

M - Send a mail

Enter the name of the feature which defines the characteristics of the mail.

Example
Infotype Field ..... Ind. Var.function part
A mail is sent when the field SACHP is changed. The characteristics of the mail are defined in feature M0001.

In the standard system, feature M0001 is provided as a model. The documentation on feature M0001 explains how to define the characteristics of a mail.

&ADDITIONAL HINTS&

The table strings T001P, T503 and PSPAR are filled with the values which are valid on the record start date.

The old values of the infotype are stored in the field string PSAVE . The structure of this string is the same as the Pnnnn structure (nnnn=infotype). The structure is filled with (valid) values only when the delete, change and create functions are used.
