Applying lcr through gst India JDE

Hi Experts

Question is regarding the gst calculation through lcr

created all the gst set ups in DV 9.2

AAI is created ,gst rule ,cost rule, liking is done

link between item, address no and cost  is also done .

Is there any other esu for P75I791? Which will help to calculate gst ?

After all the above activity

We have created the po and when trying to receive the po through lcr then the system is not getting calculated

lcr is activated through the po too .

we can see only  blank screen  ( if we apply any other lcr the pertaining to purchase same can be seen )
