Hello,
There are two options to do resend/redistribute your delivery to EWM.
1 Try to edit the Delivery status using ABAP Help in Debug mode and change the status as 'A-Not Distributed Mode'. Then, Try to distribute again using VL06ID Tcode.
2 Try to change little delivery information using VL60 Tcode. And Save. System redistributes the changes. but, VL60 Tcode will lot of time to get it execute. Since, It fetches all the deliveries.
or
Try to repeat the Output type, If you are using any. This will redistributes the delivery again. But, This set up will not exist in lot of system. and suitable most of the times.
Regards,
Sathish
