Q5. What Is Logical Data Base?

Logical data bases are unique packages used to examine the facts and make it available within the programs. Other than retrieving the information authorization checks are handled, can be capable of retrieve records from multiple tables.

Q6. Explain The Program Flow When We Use Logical Database Pnp Or Pnpce?

If you operate any of the LDBs, this system glide is as underneath

Report XXXXXX.

Data announcement

START_OF_SELECTION.

GET PERNR.

Retrieve the records from inner tables to output inner tables

END_OF_SELECTION.

Display the records retrieved above.

From GET PERNR to END_OF_SELECTION ; it's going to loop with the employee numbers

decided on from the choice display.

 

Q7. What Are The Time Related Infotypes?

All the 2 collection Infotypes.

Q8. Why Do We Require Infotypes For Hr Module?

As all different modules uses standard SAP tables concept to shop the records. HR module makes use of the brand new and distinct idea to keep the records i.E., Infotypes. Data is scattered b/n Infotypes by using depending above the type of records and this makes to easily get right of entry to similar statistics of all personnel at one stretch by minimizing the retrieval time. As HR records is totally time dependant and have more range information to save and retrieve for a selected cause.

Q9. Explain Get Pernr Concept When We Use Logical Data Base?

You want to apply LDB PNP to use the GET PERNR occasion, as soon as GET PERNR event triggers all of the Infotypes declared by means of the use of INFOTYPES declaration may be fetched data to the respective internal tables. If you specify Infotypes by using INFOTYPES assertion then inner tables are created with Pnnnn shape. 

Ex:- INFOTYPES: 0001, 0002, 0006.

Internal tables p0001, p0002, p0003 are created and may be used inside the software.

To retrieve the statistics from repetitive structures we use DO… VARYING command as under

DATA: BEGIN OF WAGETYPES,

LGA LIKE P0008-LGA01,

BET LIKE P0008-BET01,

ANZ LIKE P0008-ANZ01,

EIN LIKE P0008-EIN01,

OPK LIKE P0008-OPK01,

END OF WAGETYPES.

GET PERNR.

RP_PROVIDE_FROM_LAST P0008 SPACE PN-BEGDA PN-ENDDA.

DO 20 TIMES VARYING WAGETYPES

FROM P0008-LGA01

NEXT P0008-LGA02.

IF WAGETYPES-LGA IS INITIAL.

EXIT.

ELSE.

WRITE: / WAGETYPES-LGA, WAGETYPES-BET.

ENDIF.

Infotypes will have three systems PAKEY, PSHD1, PSnnnn [ nnnn is Infotype number]. PAKEY(Key fields) and PSHD1(Control Fields) is same for all the Infotypes. Fields within the PSnnnn structure relies upon at the Infotype makes use of, like 0000- Actions will the fields precise to motion of an employee 0002-Personal Data may have fields precise to the private information fields(name, DOB, and many others..) of an employee.
