Dynamic Action It0021 - IT0019

Question

Hi All,
I am able to create records in IT0019 whenever a child is maintained in IT0021.
But on deletion of child record in IT0021 the corresponding record in IT0019 should also be deleted.
Is this possible?
Regards,
Swati

Answer 1

The step determines what should be done. It can have 6 values:
P - check conditions under which something is done
I - maintain infotype record
W - set default values for new record
V - Reference to another step
F - call a routine
M - send mail
The variable function part
The variable function part must always be seen together with the action because the action determines what happens in the variable function part. We got 6 different actions: P, I, W, V, F and M.
P: Plausibility checks, which allow you to check certain conditions.
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:
= equals
< less than
<= less than or equal
> greater then
=> greater then or equal
<> not equal
Consecutive checks must be linked by a logical AND. Logical OR links must also be indicated by a /X.
The variable function part with action I Calls an infotype for processing
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. The possible actions are INS, COP, MOD, and DEL.
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 D (/D). A slash S (/S) will also suppress dialog.
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.
Example:
Infotype Field .... Ind. Variable function part
.... I INS,19,01/D
Step: Create a Dates record, subtype 01, run in the background
.... I DEL,14,M559
Step: Delete Rec. Payments/Deds. record with subtype (wage type) M559.
0007 .... I INS,8,,,(P0007-BEGDA),(P0007-ENDDA)
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.
The complete syntax can be :
Action - INS, MOD, COP, DEL
Infotype
Subtype
Object-ID
Start date 
End date
/D Action in background
W
Default values for new record
Called after the I statement and used to assign values to screen fields while creating or copying another infotype record through the I statement 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.
F: Call a routine
Calls a FORM routine (subroutines in ABAP) during your action. The routine may reside in or out the module pool MPNNNN00.
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
  Infotype Field ..... Ind. Var.function part
  0016 PRBZT F PROBATION
  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.
V
Cross-reference to another step
Lets you treat collectively a number of fields for which you want to define a common dynamic action 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.

Sends SAP Office mail
Enter the name of the feature which defines the characteristics of the mail.
