Table structure of Time Management Add-on

Hello everyone,

i have a relatively simple question. I am trying to figure out how the PTREQ* and PTARQ* tables are connected. What I dont understand yet is which of those tables (maybe PTREQ_HEADER or PTREQ_ATTABSDATA) is the leading table and how they are all logically connected.

Especially, when I have a certain personnel number how do I get all the corresponding data entries in the tables?

Does someone have an idea or maybe a papar from SAP regarding this topic?

The tables I mean:

PTREQ_ACTOR

PTREQ_ATTABSDATA

PTREQ_CKEY_MAPP

PTREQ_BATCH

PTREQ_HEADER

PTREQ_ITEM_TYPES

PTREQ_ITEMS

PTREQ_NOTICE

PTREQ_STATUS_CHK

PTREQ_STATUS_TRA

PTREQ_TYPE

PTREQ_XFEREVENTS

PTREQ_EFEREVNT_T

PTARQ_ATTS_INFO

PTARQ_DEDUCTION

PTARQ_EXTRA_INFO

Thanks in advance!

Marcus
