ATP Orders deletion

Hi All,

I tried to delete the ATP order of one single product through program /sapapo/sdorder_del. But its not deleting.

I checked the same order in va03 of R/3 system to check whether any product having the same ATP orders and i got 3 products.

Then i checked these 3 products in WUF in APO system to check whether any LC orders are linked to the ATP order (which i want to delete).

I got the 2 LC orders..

Do i need to delete this LC orders first?

So please help out in deleting the ATP order.

With Regards,

Santosh G C
