In our scenario we purchase equipment,
P.O >> Goods Receipt (maintaining serial number and generating equipment master)
Then in equipment master under serial data stock information is updated (Plant,storage location,batch,master batch,last movement date).
But when I sell this equipment the last movement date is updated and all other data disappear.
That I want prevent,because our batch-classification contains lot of information like engine no. engine serial,model etc.
How to prevent this so batch can stay as it is
