Answer 1

i need ur help regarding the Sales order item category redetermination.
         we are having two item categories YNAE and YNAG and it contain schedule  line categories CP and CB ( i.e for item category  YNAE schedule line category is CP and 
         for item category  YNAG schedule line category is CB), for YNAG Purchase Requisition is automatically created becz of functional setting on save and it is working fine.
         For every line item in sales order line item level item category YNAE will be determined by default as per functional settings.
         Now my requirement is that, if sales order line item doesn't contain 100% confirmed quantity, than i needs to change the default line item category YNAE to YNAG
         which i am trying to do it in USEREXIT_PRICING_PREPARE_TKOMP becz in this exit i am getting the values in XVBAP and XVBEP and  it is working fine .
         But schedule line category is not getting redetermined automatically what i mean is, if i change the item category to YNAG from YNAE in user exit corresponding schedule line category CB of YNAG is getting determined automatically at the schedule line level and if ichange the schedule line categories in XVBEP in exit USEREXIT_PRICING_PREPARE_TKOMP, changes are reflecting at the schedule line level but Purchase requisation is not getting created for schedule on SAVE and its delivary dates are also not getting determined properly. If press the option ATP check at the schedule line level than very things will getting corrected in the order.
i am using UPDKZ = U  in both xvbap and xvbep for changes
I feel that i am not doing this in proper way, do u have any idea about how to redetermine item category. please let me know if u have any idea .
