COR1 Batch Number

Hi all experts,

i want to do the enhancement in cor1 by passing batch number from the general data screen

To the material screen.

I am using user exit PPCO0007 to do the enhancement; however, i can't find the fields or table that store this value or pass this value to.

I believe PPCO0007 is using HEADER_IMP LIKE CAUFVD as structure to store data, but still i can't find the field that have the batch value.

Please help and guide me.
