start and end dates update IW31 tcode

[uirji_netweaver]

Hi

I have an requirement that when work order is released system should take the basic start date on the work order (AFKO-GSTRP) at the time of release and set the constraint “Must Start On” (AFVV-EINSA) for the 1st active operation (i.e. operation is not deleted) and set the basic start date as the date on the operation constraint (AFVV-NTANF). 

i have found the exit (IWO10009 ),but my question is how can i update the basic start date as date of operation in Date tab.

is there any FM available for update?

Please help me.

Regards

Niru

You can achieve this by using fm CO_BT_AFVG_UPDATE in the exit IWO10009 (or in BAdi WORKORDER_UPDATE). Another fm CO_BO_OPR_OF_ORDER_GET helps you to get runtime values of operation fields.
