Profit center Time dependent and other Time Dependent Master Data

Question

Hello Friends . I ticked one of the attribute of 0Vendor -
Attribute = Profit center Time dependent. Now I get
Date To and Date From Field. I read that we need to set this in BI via routine. Can u Suggest the below
Date From Field = GO live Date
Question 1 : If I set Date To FIELD to be Month end like for oct 10/31/2007 and make a routine that will increase the Date To FIELD to November 11/30/2007. Will it spoil the load since I read in SAP Expert that we cannot have same date to field. But i guess we can have it, Like If i load it today Date to will be 10/31/2007 and tomorrow load will also have 10/31/2007 . so it will have monthly snap shots of master data
Question 2 : what is advisable if I create Daily snap shots of master data like Date To FIELD will be Loading Date . Will that logic in routine to create daily loading date set to Date To FIELD will overburden the system and make the system die in few months or it is ok. we will have about 12 fields which will be time dependent.
Question 3: If you have any routine that set Date To field please email me at [email protected]
Please help

Answer 1

Soniya,
If you really need to do it, Quarterly is a better option than monthly so that you can reduce the number of records in master data.
For the time stamp, you will have to write some code.
Since you are going to use 0PROFIT_CTR object, the business content on this is still based on the old data flow. You have multiple places to write this code. The best place is to create a transformation between your Infosource and the InfoObject. Once you have the update rule, you can write a start routine.
you have to populate the date from and date to field.
date to = first day fo the current qtr.
date from = last date of the current qtr.
to get the first date and last date you can use the following logic.
1. pass current date and fiscal variant to fm DATE_TO_PERIOD_CONVERT.
2. get the first period and last period from the output of 1. (for example, the current date is converted to period 003, and year 2007, then for this value the first period will be 001, and last period will be 003 and so on)
3. use fm FIRST_DAY_IN_PERIOD_GET to get the first date of the period.
4. user fm LAST_DAY_IN_PERIOD_GET to get the last date of the period.
