Process Infotypes

RMAC Modules - RMAC module as referred to Macro, is a special construct of ABAP/4 codes. Normally, the program code of these modules is stored in table 'TRMAC'. The table key combines the program code under a given name. It can also be defined in programs.The RMAC defined in the TRMAC can be used in all Reports. When an RMAC is changed, the report has to be regenerated manually to reflect the change.

Reading Infotypes - by using RMAC (macro) RP-READ-INFOTYPE

REPORT ZHR00001.
INFOTYPE: 0002.
PARAMETERS: PERNR LIKE P0002-PERNR.
RP-READ-INFOTYPE PERNR 0002 P0002  .
PROVIDE * FROM P0002
if ... then ...endif.
ENDPROVIDE.

Changing Infotypes - by using RMAC (macro) RP-READ-INFOTYPE.
· Three steps are involved in changing infotypes:
1. Select the infotype records to be changed;
2. Make the required changes and store the records in an alternative table;
3. Save this table to the database;
The RP-UPDATE macro updates the database. The parameters of this macro are the OLD internal table containing the unchanged records and the NEW internal table containing the changed records. You cannot create or delete data. Only modification is possible.

INFOTYPES: Pnnnn NAME OLD,
Pnnnn NAME NEW.
GET PERNR.
PROVIDE * FROM OLD
WHERE .... = ... "Change old record
*Save old record in alternate table
NEW = OLD.
ENDPROVIDE.
RP-UPDATE OLD NEW. "Update changed record

Infotype with repeat structures
· How to identify repeat structures.
a. On infotype entry screen, data is entered in table form.
IT0005, IT0008, IT0041, etc.

b. In the infotype structure, fields are grouped by the same name followed by sequence number.
P0005-UARnn P0005-UANnn P0005-UBEnn
P0005-UENnn P0005-UABnn

Repeat Structures
· Data is entered on the infotype screen in table format but stored on the database in a linear
structure.
· Each row of the table is stored in the same record on the database.
· When evaluating a repeat structure, you must define the starting point, the increment and the
work area which contains the complete field group definition.

Repeat Structures Evaluation (I)
· To evaluate the repeat structures
a. Define work area.
The work area is a field string. Its structure is identical to that of the field group.
b. Use a DO LOOP to divide the repeat structure into segments and make it available for
processing in the work area, one field group (block) at a time.

Repeat Structures Evaluation(II)

* Define work area
