LDB in HR

[Former Member]

hi friends,

I am having a doubt, why LDB (HR PNP...) is used in HR, and why not Open sql statements for Reports.

what is the difference between LDB and open sql statement, in what way it is benificial ?

if possible any one send me documents how to use LDB in HR ? to this mail id venkee_12345@yahoo.co.in

thank u HR consultants

Hi,

You can use open SQL statement also instead of LDB in HR for reports.

But using LDB, we get more benefits

1. Bulild in Standarad selection screen

2. Automatic Data retrieval by just declaring infotypes

3. Automatic Authorization check which is very imop in HR.

Hope this helps.

The biggest advantage of an LDB is that it 'preselects' the structure within a relationship which could be cumbersome if one has to design joins (and chances are one could go wrong!) but with an LDB you get the same structure as you get in other SAP std. PA modules/programs/reports etc.

LDB - is a SET of programs which provide u its own selection screen and commands to deal with HR data.

Hence for HR u can prefer LDB instead of SQL..

u can acheive the same thing via SQL but LDB is more easier as u need not write much code.

u have to specify in the attributes of the program ,LDb name..

like PNP,PCH etc..

here is a sample program using LDB -

REPORT ZPPL_PREVEMPLOYERS message-id rp

line-size 250

line-count 65.

*Program logic :- This Report is used to Download all the Previous
