Hi Gurus,
We have a Sales order for which GATP is getting triggered. When we try to save the sales order it takes us to the APO availability check:delivery proposal(sales order) screen which we are not able to edit. When we check the product allocation tab,the confirmed quantity is zero. The confirmed quantity in the SO screen is also zero. Is it something to do with the product allocation for the product/location? I'm relatively new to APO, so kindly
bare if these are basics..
