How to change bucket capacity for a certain date range (duration)?

Question

Hi,
I need to update the bucket capacities of Resource at Vendor location in APO live cache for a particular period using BAPI_RSSRVAPS_CHANGEMULTI.
Here I am executing BAPI by passing -
Import Parameters:
LOGICAL_SYSTEM
COMMIT_CONTROL
PLANNING_VERSION
Tables:
RESOURCE_HEAD
(RESOURCE = Resource  " Test123
LOCATION = Vendor Number/Loctaion
CAPACITY_A = 5000.000
NUM_OF_PERIODS = 001
PERIOD = 02    " Day Wise
UTIL_BUCKET = 100.000 )
RESOURCE_HEAD_X
(All corresponding fields X)
RESOURCE_QUANMODEL
(RESOURCE = Resource  " Test123
VERSION = 01
ENDDA = 02/25/2011
BEGDA = 02/21/2011
QUANMODEL = 8000 )
RESOURCE_QUANMODEL_X
(All corresponding fields X)
[ I have a capacity variance:
Resource = Test123; Capacity Varient = 01; Valid From = 02/21/2011
Valid To = 02/25/2011; Bucket Util Rate = 100.000; Qty/Rate definition = 8000 ]
Now, while I execute /SAPAPO/RES01 to display Capacity for that resource-Location-PlanningVersion, Its showing that 'Bucket Capacity' and 'SNP Bucket Capacity' get changed into 5000. But this change happend for all the days and not only for the duration I passed into Bapi (From BEGDA to ENDDA).
How to change bucket capacity for a certain date range (duration)? Any help please.
Thanks
Roy

Answer 1

I did it myself. Hence closing the thread.
Solution:
1. Get RESUID from /SAPAPO/RESKEY table by passing Resource as NAME.
2. Call Function Module /SAPAPO/CRES_QUANPROF_UPDATE
3. Call Function Module /SAPAPO/CRES_SAVE_FROM_BT
For further help, change manually a single record in the 'capacity profile' in TXN /SAPAPO/RES01 and debug both the FM mentioned above.
