Macros in HR-ABAP

Most commonly used Macros in HR ABAP ?

Macro contains some part of source code which it will be useful for number of applications.( Like function modules )

Generally we use two macros in HR ABAP
RP-PROVIDE-FROM-LAST
RP-PROVIDE-FROM-FRST

The macro RP-PROVIDE-FROM-LAST retrieves the last(latest) data record which is valid in the data selection period.
The macro RP-PROVIDE-FROM-FRST retrieves the first(start)data record which is valid in the data selection period.

For every macro, whether the operation was successful or not will be checked with PNP-SW-FOUND.
If PNP-SW-FOUND = 1 , then the operation is successful. ( same as sy-subrc but the value is in reverse case)

The macro RP-READ-INFOTYPE retrieves all the data record(s) which is valid in the data selection period.

If SY-SUBRC = 0 , then the process is successful.

All the Macros are stored in table TRMAC

Whenever you are using the macros like

RP-PROVIDE-FROM-LAST or
RP-PROVIDE-FROM-FRST,

check whether you have included logical database PNP in program attributes.

It is not necessary to include logical database PNP/PNPCE in your program when you are using the macro like

RP-READ-INFOTYPE A B C D E , where

A corresponds to PERNR which describes for which personnel number you require records.

B corresponds to INFOTYPE which describes from which infotype you require records.

C corresponds to data structure of the declared infotype (internal table like P0000 for infotype 0000) where all the records of the particular personnel number will be stored.

D corresponds to Start date.

E corresponds to End date.
