User Exit to default operations in IW31

Question

Hello Everyone,
I have the following requirements
1. I need to dafault the Operations in IW31 transaction. I have tried with the following code
1. I used cmod to open up user exit EXIT_SAPLCOIH_020.
2. Then i used cmod to open up user exit EXIT_SAPLCOIH_003
(IWO20001 PM order: User exit to pass routing to order).
Here in INCLUDE ZXWOCU03, I entered the following code
IF NOT CAUFVD_IMP-AUART = 'SM03'.
( Use above to filter order types and PMActTypes)
SEL_TAB-PLNTY = 'A'.
SEL_TAB-PLNNR = 'SAFE_INS'. "***This is the name of the task list
SEL_TAB-PLNAL = '01'.
APPEND SEL_TAB.
ENDIF.
Using the above code the Operations are getting defaulted even before entering the Maintenance Activity type (PMActType) and Base Start Date. My requirement is i want an User-Exit which fills Operations based on Order Type and Maintenance Activity Type(ILART). 
2. I also want an User-Exit to change the Control key values in the Operation tab in IW31 transaction.
Note:The version is 4.6C
Thanks in advance!
Regards,
Sandhya

Dear Saket Tiwari & Dëv Päträ
I think I've given you the not clearing impression. i mean that T-Code OLMB is for "Inventory Management and Physical Inventory" configuration. (I think that you already know about it)
1) Go to T-Code >> OLMB > Physical Inventory > Default Values for Physical Inventory  &
                             OLMB > Physical Inventory > Field Selection for Physical Inventory
    Pre-settings for entering physical inventory documents
Reason for inventory difference
     The default value you specify here is only displayed when you enter an inventory difference
     without reference to the corresponding document. But you can also change the default value.
2) and You can control "Filed selection for Physical Inventory" such as MIGO filed selection.
I think that before finding Technical Enhancement Spot, You can consider Configuration Control for your process.
I hope that my options will be helpful for your project.
