OM/PA: Tool/Report to compare pers. subarea/EE grp&subgrp values?

Question

My understanding is that IT1008 (pers area/subarea) and IT1013 (Employee group/subgroup)on the OM side default over to the PA side when an original action takes place like a new hire (when integration is turned on).  The problem is when a change is made to the 1008/1013 data on the OM side, perhaps there is an error or the user decides to change the EE subgrp on the position, for example (instead of delimiting and creating a new position).  The data can be changed on the OM side, but then when the action is run on the PA side, such as a category change action, the new information does not default over.  The old values reamin in the fields.  Only if the current values are deleted and then the user hits <ENTER> do the new values appear.  I am puzzled why SAP standard does not automatically default in the changed values on the position when a PA action is run.  Is it because it is best practice to create a new position when these values change and then enter int he new position number during the PA action?  We have a situation here where many employees area changed from one employee group to another (temporary to casual and back) in the summer.  It does not seem efficient to create new positions for all of them just to change one field value.  What is the recommended way to handle this kind of situation?  We would like to understand the best paractice for this procedurally.
This leads me to ask - is there a way to run a program that syncs personnel area/subarea and EE group and subgroup data from OM -> PA if it is out of sync?  Are there any standard reports that compare this data and print out a log of what is out of sync so that users can make corrections?  Your advise is greatly appreciated!
Thanks!

Answer 1

To clarify, I do not want to create IT1008 and IT1013.  I am wondering if I change data on one of those infotypes (which we have set-up on the position) such as employee group, subgroup, or personnel subarea, if there is a way to send those changes over to PA automatically without having to create a new position with the new information and then running an action on the PA side and inputting the new position number on infotype 0001.  We are really asking if there is a way to simply transfer changed data on IT1008 or 1013 over to the PA side from the OM position.
Example:  HR User goes into position 30000135 and changes the employee group from 2 to 5.  On the PA side, when the user goes to view infotype 0001 the employee group still says 5.  Even if the HR user goes to do a category change action on the PA side, when infotype 0001 comes up. the employee group is still 2.  This value needs to be changed to 5.  If the HR users want to keep the personnel subarea and employee group and subgroup as output only in infotype 0001 so that data entry clerks cannot change it there (so that it can only be changed in OM via the position), how can this work?
Will you please provide detail on how to use the function module 'BAPI_HRMASTER_SAVE_REPL_MULT' if it is used for this purpose?
Thanks!
